| 摘 要： | 利用80－90年代的TM影响数据，借助GIS分析了新疆塔里木河下游典型生态调查区内土地利用／土地覆盖现状及动态变化，并对塔河下游土地开发效果进行了对比分析。结果显示，耕地和城镇居住住用地的增加完全来源于对草地的开垦和对荒漠胡杨林的占用。同时，由于沙化、盐咸化等自然因素的影响和因对水资源的不合理利用所产生的土壤次生盐渍化的共同作用，控制着区内生态环境不断恶化的总体态势。

| Abstract: | Using GIS, TM images(dated during 1980-1990) are interpreted, the present situation and dynamic change of land use in the typical ecological investigation areas are analyzed at the lower reaches of Tarim river, The effects of land exploition at the lower reaches of Tarim river are compared and analyzed. It shows that the increasement of cultivated land and living space stem from reclaiming grassland and occupying desert diversiform-leaved poplar forest. The common effect, salinization desertification and secondary soil salinization controls the whole tendency of steady deterioration |
