应用多目标灰色决策分析和层次分析两种定量分析方法,对辽东水源涵养林体系骨干工程建设林种结构规划进行可行性研究,经过计算,两种结果都非常接近定性分析的林种结构比例,即用材林39 .5 % ,防护林33 .5 % ,经济林13 .7 % ,特用林5 .0 % ,薪炭林8 .3% ,从而验证林种结构的科学性、合理性和可行性。 Two kinds of quantitative analysis methods of multi-objective gray decision analysis and level analysis are applied to carry out the feasibility study on the forest structure planning of the key project of water conservation forest system in Liaodong. After calculation, both results are very close to the proportion of forest structure qualitatively analyzed, That is, 39.5% of timber stands, 33.5% of shelterbelts, 13.7% of economic forest, 5.0% of special-purpose forest and 8.3% of fuelwood forest will be used to verify the scientificity, rationality and feasibility of forest structure.
