摘要

生态风险评价是环境、资源评价与管理方面的研究热点领域，本研究以松嫩草原西部杜蒙县为研究区域，利用该区域1979，2001，2004年3个时段的TM遥感数据、以GIS技术为数据分析平台，获取20余年不同时段的土地利用信息，研究了不同年份的土地利用类型特征。在此基础上构造一个综合性生态风险指数，然后通过系统采样、变异函数分析及空间插值对生态风险指数进行空间化，研究生态风险的空间分布特征和内在的形成机制，划分出不同风险等级区域，并有针对性的提出相应的生态风险管理措施。

Abstract

It was based on TM remote sensing image during three periods of 1979

1990 and 2004 in Dumeng country

northeastern province. It uses GIS technology as the data integration analysis platform and obtains land utilization information in different periods of 20 years and conducted the land-use. An ecological risk index was constructed based on the land-use structure; The semivarogram analysis and the system sampling method was used to make it a spatial variable; the block Kriging were conducted to study the spatial characteristics and inherent causes of regional ecological risk in the working area and we put forward the protective measures in high ecological risk areas in Dumeng County.
