【摘要】 为进一步了解吉林省生境质量状况、空间分布及其与土地覆被类型之间的关系，基于InVEST模型中的生境质量模块，以吉林省2000年、2010年和2020年土地覆被数据为基础，在InVEST模型中对吉林省近20年的生境质量进行了模拟评价.结果表明：(1)2000—2020年间吉林省土地覆被类型发生了较大程度的变化，主要是草地、水域的转出及其他类型向建设用地的转入.(2)吉林省生境质量总体呈现出东南高西北低的空间特征，且不同等级生境质量的空间分布与其土地覆被类型有密切关系.(3)2000—2010年吉林省平均生境质量均处于“良好”等级，但有小幅度下降.(4)20年间，吉林市、白山市等地生境质量由于政府对于生态环境保护的重视有所提高，白城市、延边州等地生境质量则由于湿地退化、毁林毁草开荒等出现了一定程度的下降.更多还原

【Abstract】 To further understand the status and spatial distribution of habitat quality in Jilin Province and its relationship with land cover types.This research based on the habitat quality module in the InVEST model and the land cover data of Jilin Province in 2000,2010,2020.Overlay analysis of data using ArcGIS then simulate the results of habitat quality in the InVEST model. The results show that:(1) The land cover types in Jilin Province have undergone major changes from 2000 to 2020. Mainly the transfer of grassland and water areas to other land cover types and the transfer of other types to construction land.(2) The overall habitat quality of Jilin Province presents the spatial characteristics of high in the southeast and low in the northwest. And the spatial distribution of different levels of habitat quality is closely related to the types of land cover.(3) The average habitat quality in Jilin Province from 2000 to 2010 were all at the "good" level. But there was a slight decline.(4) In the past 20 years, the quality of habitats in Jilin City, Baishan City and other places has increased due to the increased emphasis on environmental protection by the provincial government. While the quality of habitats in Baicheng City, Yanbian Prefecture and other places has deteriorated to a certain extent due to wetland degradation, deforestation and grassland reclamation decline.更多还原
