| 摘 要： | 朔州平原区土壤盐碱化严重制约着当地农业的可持续发展,及时掌握盐碱地状况对于盐碱地改良和经济发展是非常必要的。在GIS,RS技术的支撑下,基于ENVI 4.7和ArcGIS 10.0平台,以地形图、土地利用现状图和2000年(ETM+)、2006年(TM)和2009年(TM)三景Landsat卫星影像为数据源,对山阴县10 a来盐碱地数量的动态变化进行了监测。结果表明,研究区内2000—2009年盐碱地面积呈不断减少的趋势。

| Abstract: | The sustainable development of agriculture of Shuozhou city has been restricted seriously by soil salinization. Timely in- formation of saline conditions is necessary for the improvement of saline alkali land and economic development. Supported by GIS and RS technology, based on ENVI 4.7 and ArcGIS 10.0, with topographic map, land-use map and Landsat satellite images of 2000 （ETM ＋）, 2006（TM） and 2009 （TM） as the data source, dynamic monitoring of the number of saline-alkali land in Shanyin county this decade has been conducted. The result was that, from 2000 to 2009, in research area of saline-alkali land area showed a trend of decreasing. |
