摘要:
为了对林地地利等级进行定量评价,以安徽省休宁县岭南林场为研究对象,选择坡度、小班离附近道路的最短距离、海拔3个因子作为林地地利等级的主导因素,运用层次分析法进行构建结构模型,通过Yaahp软件进行判断矩阵构造和一致性检验后,确定3个因子的权重值分别为0.648 3、0.229 7和0.122 0;进一步对3个因子在3个水平进行细化,对岭南林场340个小班划分的27种方案的权重值计算结果显示,岭南林场各小班地利等级主要集中在1~4级。

Abstract:
In order to quantitatively evaluate the topographical advantages of forest lands, we selected three dominant factors, the slope, the shortest distance between every subcompartment and the main road near it and the elevation , which affect the topographical advantages in Lingnan forest farm in Xiuning county, Anhui Province to construct a structural model using Analytic Hierarchy Process (AHP). The results showed that the weight of the three factors was 0.648 3, 0.229 7 and 0.122 0, respectively after constructing the judgment matrix and checking the consistency by Yaahp software. The three factors were further subdivided to three levels and the 340 subcompartments of the whole forest farm were grouped into 27 alternative schemes. The calculated weight values showed that the topographical advantages of all subcompartments concentrated in the levels of 1-4.
Key words:  analytic hierarchy process(AHP)  topographical advantages  terrian factors  weight
