内蒙古黄河流域生态环境演变研究
[目的]内蒙古黄河流域是中国重要的生态区域,深入探究其生境质量变化及其驱动因子对区域荒漠化防治、生物多样性保护以及可持续发展具有重要意义。[方法]基于 1990-2020年土地利用数据,运用GIS技术和InVEST模型评估该区域的生境质量及其变化程度,通过地理探测器分析生境质量空间异质性的驱动因子。[结果](1)该区域土地利用类型以草地为主,其次占比面积较大的是未利用地,建设用地的扩张速率最快,其变化动态度高达 1.58%;(2)生境退化度整体空…查看全部>>
[Objective]The Yellow River Basin in Inner Mongolia is an important Ecoregion in China.It is of great significance to explore the changes of its habitat quality and its driving factors for regional desertification control,biodiversity protection and sustainable development.[Method]Based on land use data from 1990 to 2020,GIS technology and InVEST model were used to evaluate the habitat quality and its degree of change in the region.The driving factors of spa…查看全部>>
