摘　　要：利用2009、2018年分辨率为1 m的卫星遥感影像,依据地理国情监测的分类体系,获取了两个年份石家庄8个区县的地表覆盖数据,展示了该区域林地、草地和水域三类自然生态空间要素10 a间的变化情况,并采用生境质量指数、水源涵养指数两项指标对该区域的生态环境状况进行了评价。归因于该区域固有的自然地理特征,大部分地区生境质量指数处在“较差”区间,水源涵养指数处在“差”的区间,且由于石家庄城市化进程较快,十年间部分区域的两项指数有小幅降低。Based on the remote sensing image data with resolution of 1m in 2009 and 2018,and the classification system of geographical condition monitoring,the land cover data of 8 districts in Shijiazhuang in two years were obtained to show the changes of three types of natural ecological space elements of forest land,grassland and water area in the region.The ecological environment of the region was evaluated using habitat quality index,water conservation index.Due to the inherent natural geographic characteristics of the region,the habitat quality index in most areas is in the"poor"range,and the water conservation index is in the"relatively poor"range.Because of the rapid urbanization of Shijiazhuang,the two indexes in some regions have decreased slightly during the ten years.

关 键 词：地理国情监测 自然生态 生境质量指数 水源涵养指数
