摘要
运用RS和GIS技术手段,对宁夏全区2011-2015年卫星遥感影像进行处理分析,获得"十二五"期间的土地利用/覆盖变化数据,利用生态环境状况指数方法进行评价分析。通过研究可以看出宁夏全区生态环境状况指数由2011年的44.51上升到2015年的45.19,5个县区生态环境质量有所改善,整体生态环境质量稳中有升。
Using the remotely sensed images of 2011-2015 years, the land use and land cover change in Ningxia Autonomous Region during the period of the Twelfth Five-Year Plan were analyzed through remote sensing(RS) and Geographic Information System(GIS) technologies, and then eco-environmental Status in this period were further comprehensively evaluated by applying Eco-environmental index method. The results showed that the ecological environment index of Ningxia region increased from 44.51 to 45.19 in the past five years, The ecological environment quality of 5 counties has improved, and the overall ecological environment quality has steadily increased.
