摘要
基于遥感(RS)和地理信息系统(GIS)技术,对兴化市的生态环境状况作分析。以2005年和2012年的影像图为数据源,经过图像预处理,通过解译与分类,得到该市2个时期土地利用状况的变化情况。在此基础上,对2个时期的土地利用类型作对比,结果表明,耕地面积减少明显,城镇、农村居民点和其他建设用地面积增加突出。分别计算2个时期的生物丰度指数和植被覆盖指数,并分析了影响生态环境的主要因素。
The ecological environment in Xinghua was analyzed by remote sensing( RS) and geographic information system( GIS). Based on the image data in 2005 and 2012,the land-use situation and its variation were obtained through image preprocessing,interpretation and classification. On this basis by compare the landuse type in the two years the results showed that the farmland area reduced obviously,while the urban area,the rural residential area and other construction land increased sharply. The biological abundance index and the vegetation cover index in the two years were calculated respectively. The main factors affecting the ecological environment were analyzed.
