摘要
在3S技术的支持下,利用2000年、2005年2007年和2009年4个时期的TM遥感数据为主要数据源,以鄂尔多斯市为研究对象对其植被覆盖度进行动态分析。结果表明:从2000—2009年,中覆盖度和高覆盖度草地、城镇工矿居民地、水域、林地的面积在整个时间段的变化都有一定的增加趋势,而低覆盖度草地、耕地、裸土地的面积呈下降趋势.研究区不同植被类型覆盖面积在不同年份的起伏变化,说明各种沙地的治理和绿化措施得到了落实,加强了植树造林、强化生态建设,生态环境有了一定的改善和好转。
In support of 3S technology, using the 2000, 2005,2007 and 2009 4 period TM remote sensing data as the main data source, Erdos City as the research object on the vegetation coverage dynamic analysis. The results showed that： from 2000 to 2009, coverage and high grass coverage, urban residents, industrial water, forest land area in the entire time period changes have increased, while the low coverage grassland, arable land, bare land area decreased. The study area of different types of vegetation coverage in different years of ups and downs, to illustrate the various sand control and green measures have been implemented, strengthening afforestation, strengthening ecological construction, ecological environment has been improved and better.
