北京八达岭林场森林多功能评价指标体系探讨

探讨了地理信息系统(GIS)在八达岭林场多功能评价中的应用,筛选出水源涵养、水土保持和观赏游憩功能的评价因子,建立一套适合八达岭林场的森林多功能评价指标体系。利用GIS的空间分析功能和专家打分确定不同的评价因子对小班功能的影响程度,制作林场森林功能区划图。结果表明:划分为水源涵养功能区的小班呈面状分布,占研究区总面积的63.8%;划分到水土保持功能区的小班呈零星点状分布,占研究区总面积的20.6%;划分到观赏游憩功能区的小班主要沿道路线分布,占研究区总面积的15.6%。该研究可为八达岭林场森林多功能经营提供参考。

Discussion on the Evaluation Indicator System of Forest Functions for Beijing Badaling Forest Farm

This article discusses the application of geographic information system(GIS) in Badaling forest farm multi-function evaluation.The purpose was to screen the factors which were used to evaluate the functions of water conservation,soil and water conservation,sightseeing and recreation and establish a set of forest multi-function evaluation system suitable for the Badaling Forest Farm.The GIS spatial analysis function and the expert scoring method are used to determine the different influence of evaluation indicators on the subcompartment functions and to produce the farm's forest function division map.The results showed that the subcompartments in the water conservation area was in the form of planar distribution,which accounted for 63.8% of the total area;the subcompartments in soil and water conservation area was scattered,accounting for 20.6% of the total area;Those subcompartments in the recreation area was disrtibuted along the road,accounting for 15.6% of the total area.This research provided a reference for Badaling forest farm to carry out management of forest multi-functions.
