Analysis of Forest Resources Current Situation Based on GIS

This paper used the forest resources of Meicheng forest farm in Dongzhi county of Anhui province as example and built forest resources management information system based on Mapinfo4.0 and Viewgis2.0.The system can realize accurate query, modification, statistics analysis and provide visual results. The results showed that the structure of forest types and tree species are not rational. The ratio of timber forest type is more than it of economical forest, special forest etc.. The quality of forest stand is lower. Based on these analysis, the paper suggested that the ratio of ecological forest, landscape forest and broad\|leaved forest should be increased respectively in Meicheng forest farm. In addition, the system can export different special subject maps such as maps of forest types distribution and trees species distribution ,and also forecast the dynamic state of forest resource ,provide the scientific base for enhancing forest management level.
