Abstract ：
Bamboo forest density is a factor that critically impacts the growth of moso bamboo, soil quality, and productivity. In this study, four bamboo forest density treatment groups were established under a long-term bamboo-stocking retention model, namely 1200 +/- 100, 1800 +/- 100, 2400 +/- 100, and 3000 +/- 100 plantshm(-2), while a traditional management model focused on selective logging, with a bamboo forest density of 2100 +/- 100 plantshm(-2) (CK), serving as the control group. The study aimed to investigate the impact of bamboo forest density on bamboo shoots, roots, and soil, identify key influencing factors, and determine the optimal management density for this management model. Under the novel management model, bamboo shoot yield and number exhibited a unimodal response to stand density. At a density of 2400 plantshm(-2), the bamboo shoot yield reached its highest value of 18,822 kghm(-2), with 7080 shootshm(-2). Under the density of 2400 plantshm(-2), the specific root length, specific root surface area and total nitrogen, phosphorus and potassium contents of 0-1 mm fine roots were higher, and the contents of soil organic matter, total nitrogen, available phosphorus and available potassium were also better. Correlation analysis showed that the bamboo shoot yield and the number of shoots were closely related to soil quality (water content, organic matter, total nitrogen, available phosphorus and available potassium), and the effect of root total nitrogen content on shoot yield was particularly significant (the explanation rate was 75.7%). The comprehensive growth status assessment (D3 > D4 > D2 > CK > D1) showed that there were differences in the performance of different density treatment groups. This information could help bamboo farmers improve yield while protecting soil quality.

Abstract ：
以福州“三坊七巷”历史文化街区为对象，通过声压级实地测量与主观问卷调查，系统分析其声环境特征及声景感知。研究发现：主街空间因商业活动密集，声压级在傍晚及晚间显著升高；声源构成中，主街以人类活动声和音乐声为主导，而坊内、巷内等空间则以生物声和自然声为主。其中自然声和生物声偏好度最高，机械声和人类活动声则显著偏低。此外，受访者性别、年龄及到访频率等因素对声源偏好存在显著影响。基于语义差异法和因子分析，声景感知维度可归纳为舒适性、秩序性、声音状态与变化。研究建议通过声压级管控、降噪措施及自然声景观设计优化街区声环境，为历史文化街区声景保护与提升提供科学依据。

Abstract ：
[Objectives] High-resolution remote sensing image segmentation provides essential data support for urban planning, land use, and land cover analysis by accurately extracting terrain information. However, traditional methods face challenges in predicting object categories at the pixel level due to the high computational cost of processing high-resolution images. Current segmentation approaches often divide remote sensing images into a series of standard blocks and perform multi-scale local segmentation, which captures semantic information at different granularities. However, these methods exhibit weak feature interaction between blocks, as they do not consider contextual prior knowledge, ultimately reducing local segmentation performance. [Methods] To address this issue, this paper proposes a high-resolution remote sensing image segmentation framework named CATrans (Cross-scale Attention Transformer), which combines cross-scale attention with a semantic-based visual Transformer. CATrans first predicts the segmentation results of local blocks and then merges them to produce the final global image segmentation. It introduces contextual prior knowledge to enhance local feature representation. Specifically, we propose a cross-scale attention mechanism to integrate contextual semantic information with multi-level features. The multi-branch parallel structure of the cross-scale attention module enhances focus on objects of varying granularities by analyzing shallow-deep and local-global dependencies. This mechanism aggregates cross-spatial information across various dimensions and weights multi-scale kernels to strengthen multi-level feature representations, enabling the model to avoid deep stacking and multiple sequential processes. Additionally, a semantic-based visual Transformer is adopted to couple multi-level contextual semantic information. Spatial attention is used to reinforce these semantic representations. The multi-level contextual information is grouped to form abstract semantic concepts, which are then fed into the Transformer for sequence modeling. The self-attention mechanism within the Transformer captures dependencies between different positions in the input sequence, thereby enhancing the correlation between contextual semantics and spatial positions. Finally, enhanced contextual semantics are generated through feature mapping. [Results] This paper conducts comparative experiments on the DeepGlobe, Inria Aerial, and LoveDA datasets. The results show that CATrans outperforms existing segmentation methods, including Discrete Wavelet Smooth Network (WSDNet) and Integrating Shallow and Deep Network (ISDNet). CATrans achieves a Mean Intersection over Union (mIoU) of 76.2%, 79.2%, and 54.2%, and a Mean F1 Score (mF1) of 86.5, 87.8%, and 66.8%, with inference speeds of 38.1 FPS, 13.2 FPS, and 95.22 FPS on the respective datasets. Compared to the best-performing method, WSDNet, CATrans improves segmentation performance across all classes, with mIoU gains of 2.1%, 4.0%, and 5.3%, and mF1 gains of 1.3%, 1.8%, and 5.6%. [Conclusions] These findings highlight that the proposed CATrans framework significantly enhances high-resolution remote sensing image segmentation by incorporating contextual prior knowledge to improve local feature representation. It achieves an effective balance between segmentation performance and computational efficiency. © 2025 Science Press. All rights reserved.

Abstract ：
【目的】高分辨率遥感影像语义分割通过精准提取地物信息，为城市规划、土地分析利用提供了重要的数据支持。当前分割方法通常将遥感影像划分为标准块，进行多尺度局部分割和层次推理，未充分考虑影像中的上下文先验知识和局部特征交互能力，影响了推理分割质量。【方法】为了解决这一问题，本文提出了一种联合跨尺度注意力和语义视觉Transformer的遥感影像分割框架（Cross-scale Attention Transformer, CATrans），融合跨尺度注意力模块和语义视觉Transformer，提取上下文先验知识增强局部特征表示和分割性能。首先，跨尺度注意力模块通过空间和通道两个维度进行并行特征处理，分析浅层-深层和局部-全局特征之间的依赖关系，提升对遥感影像中不同粒度对象的注意力。其次，语义视觉Transformer通过空间注意力机制捕捉上下文语义信息，建模语义信息之间的依赖关系。【结果】本文在DeepGlobe、Inria Aerial和LoveDA数据集上进行对比实验，结果表明：CATrans的分割性能优于现有的WSDNet(Discrete Wavelet Smooth Network)和ISDNet(Integrating Shallow and Deep Network)等分割算法，分别取得了76.2%、79.2%、54.2%的平均交并比（Mean Intersection over Union, mIoU）和86.5%、87.8%、66.8%的平均F1得分（Mean F1 Score, mF1），推理速度分别达到38.1 FPS、13.2 FPS和95.22 FPS。相较于本文所对比的最佳方法 WSDNet, mIoU和mF1在3个数据集中分别提升2.1%、4.0%、5.3%和1.3%、1.8%、5.6%，在每类地物的分割中都具有显著优势。【结论】本方法实现了高效率、高精度的高分辨率遥感影像语义分割。

Abstract ：
To explore the responses of morphological characteristics and nutrient content of bamboo rhizome to enclosure succession in Phyllostachys edulis forest in Wuyi Mountain, we investigated P. edulis forests with enclosure ages of 0, 4, 6, 11, 16, and 41 years. The results were as follows: (1) The rhizome number, flagella number, rhizome length, rhizome weight, the number of the healthy buds, weak buds, bamboo shoot buds, and bifurcated rhizomes increased and then decreased, the rhizome diameter and mean internode length decreased, and the number of the nodes without buds with the increase in enclosure years. Notably, the rhizome number, flagella number, the number of the weak buds and bifurcated rhizomes (4.42 roots center dot m-2, 90.83 knobs center dot m-2, 15.33 each center dot m-2, 2.75 each center dot m-2) were the most after 6 years of enclosure. The rhizome length, rhizome weight and bamboo shoot buds (2.92 m center dot m-2, 1.82 kg center dot m-2, 15.33 each center dot m-2) were the most after 4 years of enclosure. And the number of the healthy buds (35.75 each center dot m-2) was most after 11 years of enclosure. (2) The total nitrogen, total phosphorus, total potassium and soluble sugar content decreased and then increased with the increase in enclosure years. The total nitrogen content was the highest in CK (0 years of enclosure, 4.42 g center dot kg-1). The total phosphorus, total potassium, and soluble sugar content (0.43 g center dot kg-1, 4.47 g center dot kg-1, 17.63 g center dot kg-1) were the highest after 41 years of enclosure. The organic carbon content increased and then decreased with the increase in enclosure years, and it was the highest after 6 years of enclosure (529.98 g center dot kg-1). And the starch content increased with the increase in enclosure years. (3) The morphological characteristics and nutrient content of bamboo rhizomes were interrelated, and the levels of total soil nitrogen and water content significantly affected rhizome growth. (4) Rhizome growth was highest after 6 years of enclosure and lowest after 41 years. In conclusion, the enclosure measures implemented in the P. edulis forests of the Wuyi Mountain Nature Reserve facilitated the growth and structural optimization of bamboo rhizomes. However, the enclosure period needs to be kept below a certain threshold.

Abstract ：
Exploring the combined effects of multisensory interactions in open spaces can help improve the comfort of campus environments. Nine typical spaces on a university campus in Fuzhou were selected for this study. Subjects perceived the environment and then completed an on-site subjective questionnaire. At the same time, meteorological data (global radiation, air temperature, globe temperature, wind speed, relative humidity, and illumination intensity) were measured to determine the interactions between visual and acoustic and thermal perceptions. Differences in the meteorological parameters between the measuring points were described using a one-way ANOVA and Tukey's post hoc test, and a chi-square test of independence was used to determine significant associations between thermal, acoustic, and visual comfort, which in turn led to the study of interactions between visual, acoustic, and thermal comfort using a two-way ANOVA. The following conclusions were drawn: (1) the Thermal Comfort Vote (TCV) increased with the increasing Acoustic Comfort Vote (ACV) at all levels of thermal stress. (2) The highest and lowest Acoustic Sensation Vote (ASV) values for each sound type were derived from either "slightly cold" or "warm" conditions. Both the Thermal Comfort Vote (TCV) and the Acoustic Comfort Vote (ACV) were positively correlated. (3) When "neutral", the Thermal Sensation Vote (TSV) increased with increasing illumination intensity (LUX). (4) The Sunlight Sensation Vote (SSV) increased with the increasing Universal Thermal Climate Index (UTCI) when illumination intensity (LUX) was moderate and bright. (5) The highest and lowest Acoustic Sensation Vote (ASV) values for each sound type came from either "slightly cold" or "warm" conditions.

Abstract ：
The establishment of a new type of natural protected area system with national parks as the main body is an inevitable trend of current development, and it is also an important ways to build a more beautiful China. During tourist visits, the national park will promote a variety of ways to enhance the ecological values of tourists. Ecological values can strengthen tourists' sense of identity, but their impact on tourists' pro-environmental behavior is not discussed. Based on this, Wuyishan National Park, a world natural and cultural heritage, is selected as the case site, and the PLS-SEM analysis method is used. An empirical test was conducted on 358 valid samples collected in the field. The results show the following: (1) tourists' ecological values and place identity can positively affect their pro-environmental behaviors; (2) place identity plays a mediating role between ecological values and tourists' pro-environmental behavior; (3) place dependence and place identity play a chain mediating role between ecological values and tourists' pro-environmental behavior; (4) according to the PLS-MGA test, gender and age can play a moderating role on the influence of ecological values on pro-environmental behavior. Therefore, the managers of national parks should pay attention to the cultivation of ecological values and consider tourist attraction, as well as formulating marketing strategies and other policy suggestions according to the different characteristics of tourists. The findings of this study offer both practical guidance and a theoretical underpinning for advancing ecological tourism within the framework of natural protected areas, with national parks playing a central role.

Abstract ：
In this paper, the landscape of typical roadway trees and their planting parameters on Pingtan Island are investigated and analyzed in the field. A three-dimensional model of street trees was created using AutoCAD 2020, and Ansys Fluent 2022 was used to simulate the wind condition of trees with various planting parameters under high wind circumstances. The study explores the stress and adaptability of roadway trees in the wind environment under different planting parameters, such as different heights, plant spacing, lower shrub heights, and two-row and three-row planting with different row spacings. The results show that the wind resistance of street trees is connected to the planting parameters and that modifying the appropriate planting parameters can improve the wind stability of road green space. The height of street trees is more suitable between 6.0 similar to 9.0 m. The planting spacing should be not less than 1.0 times the crown and not more than 1.75 times the crown. The form of planting has an important effect on wind resistance. Two rows of planting of street trees have a better utility and wind resistance, and a row spacing of 2.0 similar to 6.0 m is more appropriate. The height of the lower shrubs should be lower than the height of the first branch, with 0.5 similar to 1.0 m being more suitable. Based on the results of the data simulation and analysis, this paper proposes corresponding tree species selections and planting strategies for road green belts on Pingtan Island from the perspective of street tree species, planting parameters, and planting forms to provide references for the upgrading and planning of roadway tree landscapes on Pingtan Island as well as in similar climatic regions.

Abstract ：
Fokienia hodginsii (F. hodginsii), belonging to the genus Fokienia of the Cupressaceae. F. hodginsii has significant application value due to its wood properties and great research value in evolutionary studies as a gymnosperm. However, the genome of F. hodginsii remains unknown due to the large size of gymnosperms genome. Pacific Bioscience sequencing, Hi-C mapping, whole-genome Bisulfite Sequencing (BS-Seq), long-read isoform sequencing (Iso-Seq), direct RNA sequencing (DRS), quantitative proteomics, and metabonomics analysis are employed to facilitate genome assembly, gene annotation, and investigation into epigenetic mechanisms. In this study, the 10G F. hodginsii genome is assembled into 11 chromosomes. Furthermore, 50 521 protein-coding genes are annotated and determined that 65% of F. hodginsii genome comprises repetitive sequences. It is discovered that transposable element (TE)-including introns is associated with higher expression. The DNA methylome of F. hodginsii reveals that xylem has a higher DNA methylation level compared to callus. Moreover, DRS reveals the significant alterations in RNA full-length ratio, which potentially associated with poly(A) length (PAL) and alternative polyadenylation (APA). Finally, the morphology measurement and metabonomics analysis revealed the difference of 14 cultivars. In summary, the genomes and epigenetics datasets provide a molecular basis for callus formation in the gymnosperm family.
