摘要:

了解土地利用变化对生境质量的响应特征及驱动因素可为干旱区生态保护提供科学依据。基于土地利用数据,利用InVEST模型、生境贡献率和地理探测器等方法评估土地利用变化与生境质量响应及其影响因素,并预测2030年的生境质量。结果表明:(1) 土地利用类型以未利用地和草地为主,耕地和建设用地面积分别扩张了10545 km2和1170 km2,林地、草地和未利用地面积收缩;(2) 生境质量整体水平偏低,呈持续下降的趋势,空间分布呈边缘高,中部低的特点,草地流入未利用地则生境质量明显降低,反之生境质量则显著提高;(3) 生境质量空间分布主要受高程、温度和降水的影响,且高程与降水的交互作用对流域生境质量解释力最强;(4) 2030年,生态保护情景相较于自然发展情景和经济发展情景优势显著,生境质量有所提高。未来生态保护主要从防治沙漠扩张、保护草地和水资源入手。

Abstract:

Understanding the response characteristics and influencing factors of land use change to habitat quality is essential for establishing a scientific basis for ecological protection in arid regions. In this study, we used land use data, the InVEST model, habitat contribution rate, and a geographic detector to evaluate the response and influencing factors of land use changes and habitat quality. Additionally, we predicted habitat quality for 2030. The results showed the following: (1) The land use types were dominated by unused land and grassland. The cultivated and construction land areas expanded by 10545 km2 and 1170 km2, respectively, while forest land, grassland, and unused land decreased. (2) The overall habitat quality was low and exhibited a continuous downward trend. Spatial distribution was high at the edges and low in the center. Additionally, habitat quality in grasslands adjacent to unused land decreased significantly, while overall habitat quality increased significantly. (3) The spatial distribution of habitat quality was primarily influenced by elevation, temperature, and precipitation, with the interaction between elevation and precipitation having the strongest impact on habitat quality in the watershed. (4) By 2030, the ecological protection scenario will offer significant advantages over the natural and economic development scenarios, improving habitat quality. In the future, ecological protection will primarily focus on preventing and controlling desert expansion and protecting grassland and water resources.
