摘要
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. 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.
