基于GIS的森林资源现状分析

以安徽省东至县梅城林场森林资源为例,以Mapinfo4.0和Viewgis2.0为GIS软件平台,建立梅城林场森林资源管理信息系统,利用该系统可以实现森林资源的准确查询、修改、统计和分析及其结果的可视化;同时可以实现森林资源的动态监测,为提高森林资源管理水平提供科学依据。

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.
