In the light of the complex, high-level and non-linear feature of the mathematical model which describe the transport of the coalbed methane, this paper study the fully-implicit solving method of the mathematical model in detail. Based on the complexity of the algebraic equations which are formed eventually, according to the alternating direction implicit difference pattern, this paper use the iterative method and the fully main element Gauss-Jordan eliminating method to solve equations, which is to use the iterative method to determine coefficient matrix and use the fully main element Gauss-Jordan method to solve th linear algebraic equation group, at the same time of studying the solving method of the mathematical model, according to the devising requirement of FORTRAN77 program structure, this paper draw up computer program and form the corresponding computer model, and verify the validity and reliability of the model in theory by operating the model.

3Web service is a hotspot in WebGIS study recently. Based on Web service and OGC specifications, a WebGIS system for Web service is designed. A webGIS antetype and a group of WebGIS compenents including geographic entity attribute data query, distance measure, frame choosing, contour, GML disposal and buffer analyzing ect are developed. The combination of WebGIS and service platform in application are more practical and can improve the function of the platform extremely.
