南通市生态环境遥感监测及其动态变化研究

摘要:
应用遥感技术对南通市生态环境进行监测,利用GIS技术对遥感监测结果进行解译与分析,同时对2006-2009年南通市生态环境时空动态变化进行了分析与评价。结果表明,南通市生态环境类型以耕地、水域和城乡、工矿、居民用地为主,未利用土地面积极小。其生态环境动态变化的主要特点是耕地面积普遍有小幅度减少,以城镇建设用地为主的城乡、工矿、居民用地增加较多,林地面积无明显变化;未利用土地面积有所减少,以盐碱地面积减少为主,减少的面积主要用于耕地和建设用地。

Study on Dynamic Changes of Remote Sensing and Application to Ecological Environment Monitoring in Nantong
Abstract:
By using the remote sensing technology to monitor the ecological environment of Nantong and using GIS technology to interpret and analyze remote sensing monitoring results, we analyzed and evaluated spatial dynamic changes of ecological environment of Nantong from 2006 to 2009. The results showed that the type of ecological environment in Nantong were mainly arable land , waters , urban and rural areas , industrial and mining , residential land. Unused land accounted for relatively smaller part. The main features of the dynamic change of its ecological environment was generally a slight reduction of arable land;and the urban and rural land for urban construction , mining , residential land increased considerably. There was no significant change in woodland area. While the unused land area was decreased of which the saline-alkali soil t was reduced mainly to increase the areas for farmland and construction land.
