摘　　要：生态环境脆弱性评价对认识、保护和改造生态环境,促进人与自然的和谐发展具有重要意义。应用AHP法、"敏感-弹性-压力"模型法,对呼和浩特市五个旗县进行生态脆弱性评价,探讨了呼和浩特市的生态环境脆弱性的主要特征,以及生态环境脆弱度的空间差异和不同区域生态环境脆弱性的主导成因。研究结果表明:各旗县区的生态环境脆弱性排序为武川县>和林县>清水河县>托县>土默特左旗>呼和浩特市郊区;各旗县区引起生态环境脆弱的原因有所不同,自然因素仍然是主要原因,但人类活动是其催化剂。因而对不同地区的不同脆弱性因素采取不同的对策和改进措施,恢复生态环境,实现生态环境和社会经济的可持续发展。It＇s important to evaluate the fragility of ecological environment for both protecting and improving eco-environment,and promoting hamonious development of human with nature.Using AHP method and Sensibility-Flexibility-Stress Model in this paper we evaluated the fragilities of five counties in Hohhot and studied the main characteristics of the fragility of the eco-environment in these county area.The studies have shown that the fragile order among the counties is WuchuanHelinQingshuiheTuoTumoteHohhot suburb area.The reason for the differences is varied much.Natural factors are the main ones while human activities are promoting agent.So different countermeasures should be taken in different areas for improving and restoring degraded eco-environment and realizing society and economy sustainable development.
