摘　　要：[目的]基于江西省2000—2020年5期土地利用数据,分析生境质量时空演变特征和研究区域生境质量变化的主要因素,以期为江西省土地利用规划及区域生态系统服务优化提供参考。[方法]使用InVEST栖息地质量评估模型对江西省生境质量水平进行空间测度,利用全局Moran’sI指数分析生境质量时空关联性,并运用地理探测器模型捕捉影响生境质量的主导因子。[结果]①2000—2020年,江西省生境质量整体处于较高水平,但呈现缓慢下降趋势。②江西省生境质量具有较高空间正相关性,空间分布差异性逐渐增强。③自然—社会经济驱动体系中,土地利用类型因子中林地所占比例是影响生境质量的主控因子,各驱动因子间交互作用均为非线性增强,其中距建设用地距离和耕地比例两者交互作用最大。[结论]江西省生境质量整体水平较高,空间分布差异明显,生境质量水平主要受土地利用类型的影响。[Objective]Based on the land use data of five periods in Jiangxi Province from 2000 to 2020,the spatial and temporal evolution characteristics of habitat quality and the main factors of regional habitat quality change were studied,in order to provide references for land use planning and regional ecosystem service optimization in Jiangxi Province.[Methods]The InVEST habitat quality assessment model was used to measure the spatial habitat quality level in Jiangxi Province.The global Moran's I index was used to analyze the spatiotemporal correlation of habitat quality.The Geodetector model was used to capture the dominant factors affecting habitat quality.[Results]①From 2000 to 2020,the overall habitat quality in Jiangxi Province was at a relatively high level,but showed a slow downward trend.②The habitat quality in Jiangxi Province had a high spatial positive correlation,and the spatial distribution differences gradually increased.③In the natural socio-economic driving system,the proportion of forest land in land use type factors was the main controlling factor affecting habitat quality.The interactions between each driving factor were nonlinear enhancements,with the greatest interaction observed between the distance from construction land and the proportion of cultivated land.[Conclusion]The overall habitat quality level in Jiangxi Province was relatively high,with significant spatial distribution differences.Habitat quality level was mainly influenced by land use types.
