| 中文摘要 |
| 科学识别和掌握生境质量对土地利用变化的时空响应及其内在机制是干旱区寻求可持续发展的基础.基于1990、2000、2010和2020年4期土地利用数据,采用土地利用转移矩阵模型,动态度和状态度模型,InVEST模型,地理加权回归模型.结果发现： ①1990~2020年河西走廊未利用地面积变化最大,减少3 021 km2,耕地、建设用地和水域分别增加2 343.6、739.28和416.56 km2.研究期间建设用地的动态度和状态度指数的变化最大,这与近30年快速城镇化有密切关系. ②1990~2020年河西走廊生境质量整体处于低水平但呈上升态势,呈“南高北低”的空间分异格局. 1990~2020年研究区生境质量在空间上存在空间集聚效应,H-H和H-L聚集区增加显著. ③在自然机制和人为机制共同作用下,社会、经济、自然和科技要素对土地利用变化与生境质量之间的相互关系和变动机制产生深刻影响.研究结果可为优化国土空间布局以及内陆河流域生态一体化保护与系统治理提供科学支撑. |

| Scientifically recognizing and mastering the spatial-temporal response of habitat quality to land use change and its internal mechanism is the basis of seeking sustainable development in arid areas. Based on the data of land use in 1990, 2000, 2010, and 2020, the land use transfer matrix model, dynamic attitude and state degree model, InVEST model, and geographically weighted regression model were adopted. The research results were as follows： ① From 1990 to 2020, the area of unused land in Hexi Corridor changed the most, with a decrease of 3 021 km2 and the cultivated land, construction land, and water area increased by 2 343.60 km2, 739.28 km2, and 416.56 km2, respectively. During the study period, the dynamic attitude and state index of construction land changed the most, which was closely related to the rapid urbanization over the past 30 years. ② From 1990 to 2020, the overall habitat quality in Hexi Corridor was at a low level； however, it showed an upward trend, showing a spatial differentiation pattern of “high in the south and low in the north.” From 1990 to 2020, the habitat quality in the study area had a spatial agglomeration effect and the H-H and H-L aggregation areas increased significantly. ③ Under the joint action of natural and man-made mechanisms, the social, economic, natural, and scientific factors had a profound impact on the relationship and change mechanism between land use change and habitat quality. The research results can provide scientific support for optimizing the spatial layout of land and ecological integration protection and system management of inland river basins. |
