基于GIS的将乐林场森林健康评价

GIS based forest-health evaluation for Jiangle forest farm

以福建省将乐林场为研究对象,根据研究区森林调查数据,采用层次分析法构建基于GIS的森林健康评价指标体系。利用GIS的空间分析功能评价森林的健康状况,并制作森林健康等级图。结果表明:将乐林场参与评价的1154个小班大部分处于健康状态,占林场总面积的88.761%,各健康等级比重比例依次为:健康(84.803%)、亚健康(10.116%)、优质(3.958%)和不健康(1.123%),结果可为林场森林健康经营提供科学依据。

Using JiangLe Forest Farm in Fujian Province as the research object, according to the study area forest inventory data, to build the forest-health evaluation system the using of forest health AHP based on GIS. Using spatial analysis function of GIS to evaluate the forest health level of production figure of timber production and to make the health levels map of Jiangle forest farm. The results show that：most of 1291classes of Jiangle Forest Farm is at healthy levels,with a percent of 88.761.And 84.803% of the total assessment areas were healthy,10.116%of the total assessment areas were sub-healthy,3.958%of the total assessment areas were at high quality, and 1.123%of the total assessment areas were unhealthy.
