摘　　要：复合生态区生态风险涉及的风险源及风险受体具有明显的空间异质性,并相对突出地受到社会经济因素的影响,因而更为复杂、多样.山西省属我国黄土高原区,生态系统脆弱性相对突出.近年来,省内重型能源型工业发展速度很快,自吕梁孝义市至临汾侯马市已逐渐形成较明显的以煤焦产业特征为主的复合生态带.以该生态带主要风险源——洪涝、干旱、风灾、煤焦工业污染等的危害作用为研究对象,运用地理信息系统 GIS 分析技术,以区域为尺度探讨了复合生态区生态风险评价的理论与方法,并针对其敏感性提出了区域生态环境安全的保护对策.Both the receptors and sources of risk that related to the compound biome's ecological risk must account their obviously spatial beterogeneity.As a result of comparative outstanding social economic factor,it shows even more complicated and variety.Shanxi Province belongs to the loess plateau in our country,its weak ecosystem is comparative outstanding.In recent years,the heavy and energy sources industry had developed so quick that from Luliang and Xiaoyi City to Linfen and Houma City which is main of the coal and coke industry had already gradually formed a obviously character of compound biome.This article apply the geography information system (GIS) analysis technique,taking this biome's main sources of risk-flood,drought,storm,coal and coke industry pollution etc,using the ecological scale study the theories and methods which related to the ecological risk assessment of compound biome.According to its sensitivity,it gives protection measure in regional environment safe.
