摘　　要：基于研究区2000年土地利用图形数据、土地沙漠化监测数据、环境状况公报数据以及统计年鉴数据，采用中华人民共和国环境保护行业标准《生态环境状况评价技术规范（试行）》HJ／T192—2006）规定的生态环境状况评价的指标体系和计算方法。从旗、县尺度上对科尔沁沙地的生态环境状况进行综合评价。结果表明：2000年科尔沁沙地各旗县的生物丰度指数为22．01-37．96。植被覆盖指数为25．20～45．86，水网密度指数为22．51—30．97。土地退化指数为1．47—21．06。环境质量指数为57．98～59．84，综合生态环境质量指数为25．28～33．25。根据国家生态环境状况分级标准判断．该区域生态环境状况属于较差级别．意昧着该区域植被疆盖度较差。严重干旱少雨．物种较少。存在着明显限制人类生存的因素。Based on the research land-use figure data, land desertification monitoring data, state of the environment data and statistical yearbook data in 2000, and applying the People＇s Republic of China Environmental Protection Industry Standard： Technical Criterion for Ecoerwironmental Status Evaluation （Tentative） （HJ/T 192- 2006）which provides establishment basis of indicator system for assessing ecoenvironment quality and the methods of calculation, the paper made a comprehensive evaluation for the ecological environment of Horqin Sandy Land in different banners （counties）. The results showed that in banner（county） of Horqin Sandy Land, the organism abundance index was 22.01 - 37.96, vegetation cover index was 25.20 - 45.86, rivers density index was 22.51 - 30.97, land degradation index was 1.47- 21.06, environmental quality index was 57.98 - 59.84, integrated environmental quality index was 25.28 - 33.25 in 2000. According to national ecological and environmental conditions grading standards, ecological and environmental conditions in this area was poor, which means poor vegetation cover, severe drought, fewer species, and other factors that obviously limit human survival.
