AHP法在区域林种、树种结构调整中的应用研究

通过对研究区现有森林资源系统的分析，建立了五个层次的林种，树种结构层次分析调整模型，其中既有完全层次也有不完全层次，建立了不同层次的判断矩阵，用ＡＨＰ法对林种，树种结构进行了优化调整。结果表明：林种，树种结构得到改善，用材林比例有了较大幅度的下降，其它林种有了不同程度的增加，针阔叶比从现有的１：５．８７调整１：１．６８，树种结构趋于合理。

APPLICATION OF AHP METHOD ON REGULATING STRUCTURE OF CATEGORY AND TREE SPECIES IN SOUTHERN QINLING MOUNTAINS

The analystic hierarchy adjustment model of category and tree species structure were established after analysting present-day forest resources system in research region. The model had five hierarchies,among them there were not only complete hierarchy but also incomplete hierarchy. Meanwhile, the authors set up judgment matrix of different hierarchies and optimized the structure of category and tree species with AHP. Adjusted results showed that the structure of category and tree species were improved and the proportion of timber forest was reduced largely, the propotion of others category was increased to a certain extent. The proportion of coniferous trees to broad leaved trees was adjusted from 1: 5. 87 at present to 1: 1. 68 in future,the structure of tree species is tending towards reasonable.
