摘　　要：大山区河谷阶地型血吸虫病流行区，由于地理因素、居民的生产及生活方式等原因而没有明显的易感地带。针对该特点本研究以具体环境作指标，采用环境功能评估法，定出九种各类环境担负的可能导致血吸虫病流行的功能，并据此把各类环境按所担负功能的多少分为四类，以识别危险环境。在此基础上，采用地理信息系统（ＧＩＳ）缓冲区分析法初步分析了危险环境的影响范围及相互影响。研究结果表明．在大山区现有的社会经济形态及生产结构条件下，采用环境功能法识别危险环境，进而对危险环境进行处理以消除血吸虫再感染，是简便、易行、有效的。Because of the factors such as geographic feature. production and living mode. it isvery difficult to identify definite higher risk areas in mountainous region of schistosomiasisendemic area. By assessing the function in agricultural production and daily life,the environment was classified into 9 kinds,and 4 grades of risk level. Based on the theory' of geographic information system(GIS),the impact scope and interrelationship was studied. Theresults showed that assessment of risk level in mountainous region was practical to preventvillagers from being infected.
