摘要：

地理信息系统(GIS)以空间数据库技术为核心,将空间要素与统计数据有机地结合在一起,具有直观灵活、分析功能强大、制表制图方便等优点。根据中国煤层气(CBM)目标区的特点,建立了4种原则下用于不同情形的煤层气目标区评价模型:第1种模型为全面考虑各个因素原则,第2种模型为只考虑重点因素原则,第3种模型为着重考虑重点因素原则,第4种模型为既全面考虑又兼顾重点因素原则。根据这4种模型,在常用GIS软件MapGIS基础上进行了二次开发并实现模型,以华北聚气区煤层气为例进行综合评价,目标区评价结果与实际情况基本相符。

关键词: 煤层气（CBM）, 模型, 耦合, GIS, 模糊综合评价

Abstract:

With the spatial database,combining the spatial elements and statistic data,geographical information system(GIS)has many advantages, including visualization and flexibility, strong analytical function, convenient tabling and charting.According to the characteristics of coalbed methane(CBM)target area, four types of models for evaluation of CBM target area in different situations were built.The first type considered all factors, and the second only took account of key factors, and the third emphasized key factors, and the fourth considered all factors and key factors.A MapGIS software system based on these evaluation models was developed to assess  CBM target area.With this software a fuzzy comprehensive evaluation was conducted to assess the CBM target area in North China,and it was revealed that the evaluation result was  accorded with the true situation of this area.

Key words: coalbed methane（CBM）, model, couple, GIS, fuzzy comprehensive evaluation
