基于WebGIS的森林健康评价与区划专家支持系统的设计与实现

摘要

为了解决森林经营单位森林健康状况的评价问题,利用综合因子评价法建立了改进的林分级森林健康评价指标体系,并基于ArcGIS Server开发了森林健康评价与区划专家支持系统.以八达岭林场为例进行了森林健康评价与区划.结果表明,该系统可辅助实现森林经营单位健康状况判定、区划、出图、查询和统计等功能,并可以根据已有数据自定义评价指标体系及实时生成评价结果.%To solve the problem of forest management units in the assesment of forest health, this article established the improved forest health assessment index system and developed ArcGIS Server-based expert supporting system for forest health assessment and zoning. Finally, this system is used to assess the forest health condition of Badaling Forest Farm. The results show that the system can help forest management u-nit determine health status, zone, map, and achieve query and statistical functions. Further more, this system allows users to customize assessment index system and generate real time results.
