(2) 锡林郭勒盟荒漠化程度存在明显的区域性, 从西南到东北荒漠化程度呈现由高到低的变化特征, 东北部部分地区出现恶化现象, 东乌珠穆沁旗中部的水域明显变为极重度荒漠化. 西南部恶化现象严重, 苏尼特左旗、 二连浩特市和苏尼特右旗的轻度荒漠化明显变为中度荒漠化. (3) 1990~2010年锡林郭勒盟荒漠化面积呈减少趋势, 水域面积呈减少趋势, 居民工矿用地呈增加趋势.%In this study, the dynamic change of the desertification in Xilinguole League was analyzed using remote sensing and GIS, combined with field investigation and on the spot investigation to provide references for the Xilinguole League desertifica-tion disaster prevention and mitigation. The results showed that: (1) The desertification area of Xilinguole League from 1990 to 2010 showed a decreasing trend and the moderate desertification was the dominate. Light desertification area decreased first-ly, then increased, at last decreased again; moderate desertification area decreased firstly and then increased, severe deserti-fication and very severe desertification increased first and then decreased, but the latter reduced more and made the environ-ment better. (2) The desertification degree in Xilinguole League had obvious spatial variation characteristics. Desertification degree was changing from high to low at from southwest to northeast, some region of north-eastern part deteriorated seriously, such as the waters in the middle of East Ujimqin became very severe desertification. Some regions in southwest such as Sonid Left Banner, Erenhot City and Sonid Right Banner the light desertification area was changed into moderate desertification. (3) In Xilinguole League from 1990 to 2010, the desertification area reduced apparently and the waters area had a trend of reduc-ing, while the residents and the mining land area showed an increasing trend. 【总页数】6页(P1-6) 【作 者】李雨薇;李春兰;刘静;银山;包玉海;包慧娟;阿拉腾图娅 【作者单位】内蒙古农业大学生态与环境学院, 内蒙古 呼和浩特 010020;华东师范大学地理科学学院,上海 200241;内蒙古农业大学生态与环境学院, 内蒙古 呼和浩特 010020;内蒙古师范大学地理科学学院, 内蒙古 呼和浩特 010022;内蒙古师范大学遥感与地理信息重点实验室, 内蒙古 呼和浩特 010022;内蒙古师范大学遥感与地理信息重点实验室, 内蒙古 呼和浩特 010022;内蒙古师范大学地理科学学院, 内蒙古 呼和浩特 010022;内蒙古师范大学地理科学学院, 内蒙古 呼和浩特 010022 【正文语种】中 文 【中图分类】S158.1 【相关文献】 1.近20年来黄河三角洲土地利用与覆被动态变化——以东营市为例 [J], 侯艳晶;齐善忠 2.近20年城乡交错带土壤养分时间空间变异特征分析--以北京市大兴区为例 [J], 孔祥斌;张凤荣;王茹 3.城市建设用地动态变化及时空演变特征分析——以合肥市包河区为例 [J], 张思乔; 王晨光 4.华东地区典型县域近20年土地利用动态变化分析——以宜兴市为例 [J], 冉小伟;邓良基;潘根兴 5.基于MODFLOW的地下水动态变化特征分析——以位山灌区为例 [J], 王艳茹;徐征和;王通 因版权原因，仅展示原文概要，查看原文内容请购买 本文来源：https://www.wddqw.com/doc/2333424ca000a6c30c22590102020740be1ecdfa.html
