摘要
为了解决森林健康评价过程自动化与结果可视化的问题,本文采用C#语言结合ArcGIS Engine组件开发森林健康评价辅助系统。该系统参考以往森林健康评价研究中所常用的评价指标体系、指标权重确定方法、评价模型及分级标准技术,并将这些指标、算法及模型内嵌于系统中,实现了辅助森林健康评价的作用。该系统可辅助实现两类林分尺度森林健康评价过程:针对森林小班的森林健康评价,输入数据为多边形Shape文件;基于固定样地调查数据的森林健康评价,输入数据为Excel表格文件。最后,以2011～2012年44块固定样地调查数据和2009年塔河林业局盘古林场二类调查小班数据为数据源,进行了两类森林健康评价演示。
In order to solve the problem of process automation and result visualization in forest health assessment,a forest health assessment auxiliary system（FHAAS） was developed using C# programming language and ArcGIS Engine components in this paper.The system referenced the common forest health assessment indicator system,weight method,evaluation model and classification techniques in the previous studies,and above indicators,algorithm and model were embedded in this system.The forest health assessment auxiliary role was achieved by using FHAAS.The system could assist two kinds of forest health assessment process in stand scale： one is in view of subcompartment with input file format of polygon shapefile（＊.shp）;the other is in view of fixed plot with input file format of Excel 97-2003（＊.xls）.Finally,taking 44 fixed plots investigation data from 2011 to 2012 and secondary class survey data of Pangu Forest Farm at Tahe Forestry Bureau in 2009 as data source,two kinds of forest health assessment demonstration were done by using this system.
