土地变化动态监测
dynamic monitoring of land use change
tudi bianhua dongtai Jianee土地变化动态监测(dynamic~itoring of land usechange)按照一定的时间序列对土地面积、质量、分布的变化进行的调查。其目的是及时掌握土地的利用状况变化。监测的方法有连续普查和抽样调查两种。例如,1980~1983年,中国利用美国陆地资源卫星多光谱扫描图像资料进行了全国分省巧种地类的土地利用或土地覆盖调查;1993~1995年,又利用美国陆地卫星专题制图仪资料进行了全国分省、分县的6个一级类、22个二级类的土地利用现状调查。通过两次的土地利用现状普查对比,了解全国和分行政区(省、地、县)的土地利用变化,达到监测的目的。抽样调查方法按概率论原理统计推算出各类土地变化情况,具有速度快、费用低等优点,但不能定位和制图。(刘海启)
