Abstract ：
The imbalance between the supply and demand of urban ecosystem services significantly impacts land resource utilization and residents' quality of life. This study innovatively examines the spatio-temporal evolution of these services at the block scale in Xiamen, China, from 2012 to 2022, addressing a gap in current research that often focuses on larger scales like watersheds. Using multi-source data, six ecosystem services, including water conservation, carbon sequestration, and habitat quality, were assessed, revealing notable deficiencies. The study also employs the GMOP-PLUS model to simulate land use and ecosystem service changes under three scenarios-Natural development (ND), Economic development (ED), and Ecological low-carbon development (EL)- projected to 2027. Results highlight a significant spatial imbalance with a "North Supply, South Demand" pattern, particularly in southern urban areas. While all scenarios show a decline in green space and ecosystem services, the economic growth scenario improves economic benefits, and the ecological conservation scenario enhances low-carbon and ecological services. This research provides novel insights and optimization strategies for urban land use planning, aiming to enhance ecosystem services and support sustainable urban development.

Abstract ：
The analysis of visibility in urban parks is an essential component of landscape spatial analysis, and it holds significant importance for human well-being, health, and the transition to sustainable urban development. LiDAR point clouds offer highly detailed and accurate depictions of the urban park environment, and the calculation of visual volume can effectively quantify the visual perception indicators of urban parks. However, current methods often overlook the sparsity of ground point clouds, leading to inaccuracies in visual volume calculations. In light of this, we propose a theory of "boundary-ground-air" integration based on the "point cloud-ray-polyhedron" method to characterize the three-dimensional visibility of urban parks. The visual volume is divided into two major parts: ground and sky. Our method optimizes the calculation of visual volume for the ground part by supplementing missing point clouds based on ground continuity to enhance the accuracy of visual volume calculations. The method involves 5 key steps: identifying the boundary between ground points and non-ground points, voxelization of point clouds, calculation of aerial visual volume, calculation of ground visual volume, and volume index calculation. This method not only enables the calculation of three-dimensional visual space at any viewpoint in different locations within the landscape but also addresses the issue of accuracy deviation in visual volume calculations caused by the sparsity of ground point clouds. Using Chating Park in Fuzhou, China as a case study, the results demonstrate that our proposed method can accurately simulate the visibility measurement of urban parks at a resolution of 1m x 1m. This research achievement can provide technical support for landscape architecture planning and smart city development.

Abstract ：
Determining the minimum sampling area is crucial for accurate and cost-effective biodiversity surveys. This study identifies the main factors (e.g., species richness and evenness) influencing the inflection point method and precision method, aiming to scientifically establish the minimum sampling area for studying the shrub layer diversity of the Pinus massoniana community on Sandu Island, Ningde. Using 64 nested samples (20 m x 20 m) from eight sampling plots, we analyzed the species-area relationship and minimum sampling area. Key findings include the following: (1) The power function model (S = 4.053A0.404) best described the species-area relationship. (2) Species richness significantly influenced the inflection point method, with rare species increasing the required sampling area. (3) Species distribution uniformity and sampling methods affected model outcomes. (4) Repeated sampling from the four corners of the plots reduced bias caused by uneven species distribution. (5) Considering cost, accuracy, and inflection points, a minimum sampling area of 142 m2 achieved 70% sampling accuracy. This study provides a methodological framework for accurate minimum sampling area analysis and offers valuable insights for biodiversity studies of P. massoniana shrub layers in island ecosystems, with implications for international research on similar forest communities.

Abstract ：
Urban parks play a key role in mitigating urban heat island effects, yet the diurnal dynamics influencing their cooling performance remain insufficiently explored. This study investigated the diurnal variations in cooling effects across different types of urban parks in Fuzhou, China. Using multiple stepwise regression, the influence of two-dimensional (2D) and three-dimensional (3D) factors on diurnal cooling patterns was assessed. Additionally, cooling thresholds were identified based on the law of diminishing marginal utility. Results indicated that the park cooling intensity (PCI), park cooling gradient (PCG) and park cooling area (PCA) generally increased with park size throughout the day, whereas the park cooling efficiency (PCE) declined. The key determinants of cooling effects varied with park types: the difference between the contribution of 2D and 3D factors to the cooling effect of small and medium parks was not significant throughout the day, whereas large parks were primarily influenced by 2D factors. Buffer characteristics significantly affected cooling effects of all park types. The threshold value of cooling efficiency (TVoE) and the threshold value of cooling benefit (TVoB) varied across park types and exhibited temporal dynamics. These findings support balanced strategies for diverse urban parks' cooling goals from an all-weather perspective, effectively addressing urban heat challenges.

Abstract ：
As unique geographical entities, island cities boast abundant ecological resources and profound cultural values, serving as critical hubs for maintaining ecosystem services in coastal transition zones. Ensuring the stability of ecosystem services is strategically significant for sustainable urban development, while the construction of Ecosystem Service Networks (ESNs) has emerged as a core strategy to enhance ecological functionality and mitigate systemic risks. Based on current research gaps, this study focuses on three key questions: (1) How to construct a Composite Ecosystem Service Index (CESI) for island cities? (2) How to identify the Ecosystem Service Networks (ESNs) of island-type cities? (3) How to optimize the ecosystem service networks of island cities? This study selects Pingtan Island as a representative case, innovatively integrating the InVEST and MaxEnt models to conduct a comprehensive assessment of ecological and cultural services. By employing Principal Component Analysis (PCA), a Composite Ecosystem Service Index (CESI) was established. The research follows a systematic technical approach to construct and optimize the ESN: landscape connectivity indices were applied to identify ecological source areas based on CESI outcomes; multidimensional resistance factors were integrated into the Minimum Cumulative Resistance (MCR) model to develop the foundational ecological network; gradient buffer zone analysis and circuit theory were sequentially employed to refine the network structure and evaluate ecological efficacy. Key findings reveal: (1) Landscape connectivity analysis scientifically delineated 20 ecologically valuable source areas; (2) The coupled MCR model and circuit theory established a hierarchical ESN comprising 45 corridors (12 Level-1, 14 Level-2, and 19 Level-3), identifying 5.75 km2 of ecological pinch points, 7.17 km2 of ecological barriers, and 84 critical nodes-primarily concentrated in cultivated areas; (3) Buffer zone gradient analysis confirmed 30 m as the optimal corridor width for multi-scale planning; (4) Circuit theory optimization significantly enhanced network current density (1.653 -> 8.224), demonstrating a leapfrog improvement in ecological service efficiency. The proposed "assessment-construction-optimization" integrated methodology establishes an innovative paradigm for deep integration of ecosystem services with urban spatial planning. These findings provide practical spatial guidance for island city planning, supporting corridor design, conservation prioritization, and targeted restoration, thereby enhancing ecosystem service efficiency, biodiversity protection, and resilience against coastal ecosystem fragmentation.

Abstract ：
Chinese fir, as a crucial fast-growing tree species in the hilly regions of southern China, exhibits spatial structure characteristics that directly influence both the ecological functionality and productivity of its stands. This study focused on Chinese fir plantations in the Yangkou State-Owned Forest Farm, Fujian Province. Using UAV-LiDAR point cloud data, individual tree parameters such as height and crown width were extracted, and a DBH inversion model was constructed by integrating machine learning algorithms. Spatial structure parameters were quantified through weighted Voronoi diagrams. A comprehensive evaluation system was established based on the combined weighting method and fuzzy evaluation model to systematically analyze spatial structure characteristics and their evolutionary patterns across different age classes. The results demonstrated that growth environment indicators (openness and openness ratio) progressively declined with the stand's age, reflecting deteriorating light conditions due to increasing canopy closure. Growth superiority (size ratio and angle competition index) exhibited a "V"-shaped trend, with the most intense competition occurring in the middle-aged stands before stabilizing in the over-mature stage. The resource utilization efficiency (uniform angle and forest layer index) showed continuous optimization, reaching optimal spatial configuration in over-mature stands. This study developed a spatial structure evaluation system for Chinese fir plantations by combining UAV data and cloud modeling, elucidating structural characteristics and developmental patterns across different growth stages, thereby providing theoretical foundations and technical support for close-to-nature management and the precision quality improvement of Chinese fir plantations.

Abstract ：
Urban parks play a crucial role in mitigating urban heat stress and maintaining ecological stability through their cold island effect (PCIE). However, studies examining how multidimensional urban morphology influences these effects, particularly from a diurnal perspective in island cities, remain limited. This study investigates 30 representative urban parks within a typical island city, exploring how two-dimensional and three-dimensional spatial morphological factors affect four key PCIE indicators: park cooling intensity (PCI), park cooling gradient (PCG), park cooling area (PCA) and park cooling efficiency (PCE) across different times of day and night. The results reveal that: (1) coastal zones exhibit significantly lower land surface temperature (LST) than inland zones, with peak LST occurring at 5:00 p.m.; (2) the four cold island indicators follow a diurnal pattern of 5:00 p.m. > 1:00 a.m. > 7:00 a.m.; (3) morphological construction factors-such as building density (BD) and built-up proportion (BP)-positively contribute to cooling effects at 7:00 a.m., while park perimeter (PP) enhances cooling performance at both 5:00 p.m. and 1:00 a.m. Additionally, vegetation characteristics surrounding parks, including the normalized difference vegetation index (NDVI) and green space proportion (GP), influence daytime cooling in directions opposite to those of the aforementioned construction-related factors. These findings offer valuable insights into the temporal dynamics and spatial determinants of urban park cooling in island cities, providing a scientific basis for scientifically informed park planning and contributing to healthier and more sustainable urban development.

Abstract ：
Acacia melanoxylon is a high-quality timber species renowned for its superior heartwood and wide global use. To assess its stability, adaptability, and productivity in Fujian Province, China, a regional trial involving 47 A. melanoxylon families was conducted across four sites. The study utilized best linear unbiased prediction (BLUP) breeding values were estimated using 5-year-old diameter at breast height (DBH) and tree height data, and genotype plus genotype-by-environment (GGE) biplots were used to evaluate families and trial sites. The biplot generated based on BLUP values for DBH revealed that the four trial sites clustered into two groups. Group 1 comprised sites ZX (Zhangpu Zhongxi State-owned Forest Farm, Zhangpu County), LX (Quanzhou Luoxi State-owned Forest Farm, Quanzhou City), and XQ (Nanping Xiqin Teaching Forest Farm, Nanping City), while Group 2 included site LS (Nan'an Luoshan State-owned Forest Farm, Nan'an City). Sites LX and XQ showed strong positive correlations with each other and moderate correlations with ZX, indicating similar family rankings. In contrast, LX was negatively correlated with LS, reflecting opposing trends in genotype performance. Site ZX exhibited high discriminative power and representativeness, identifying it as the most effective location for evaluating families. Families 38, 35, 9, 17, and 24 demonstrated a combination of high yield and stability, underscoring their potential for extensive cultivation. The measurement of DBH is more cost-effective and accurate compared to tree height, and it aligns with our breeding objectives. Therefore, this study primarily focused on DBH for selection, and the results provide a theoretical foundation for promoting Acacia melanoxylon in Fujian Province.
