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。
This paper discussed the application of GIS in the multi-functional evaluation of Badaling Forest Farm, screened the evaluation factors of water conservation, soil and water conservation and ornamental recreation functions, and established a set of multi-functional evaluation index system suitable for Badaling forest farm. GIS spatial analysis function and expert scoring to determine the different evaluation factors on the impact of small class function, making forest function zoning map. The results showed that the small classes divided into water conservation functional areas were distributed in the shape of a plane, accounting for 63.8% of the total area of the study area. The small classes classified into functional areas of soil and water conservation were sporadic, accounting for 20.6% of the total area of the study area. The small classes for viewing recreational functional areas are mainly distributed along the road routes, accounting for 15.6% of the total area of the study area. The study can provide reference for multi-functional forest management in Badaling Forest Farm.
