摘要

本文将模糊综合评判方法应用于沙坡头人工生态防护林体系中固沙植物水分利用效率的研究.对各实验样地不同层次的水分状况构造隶属函数,根据根系分布范围给出权重因子集合,对两种固沙植物油蒿(ArtemisiaordosicaKrash.)和柠条(CaraganakorshinskiiKom.)在8种不同配置格局下的水分利用效率排序和评价,从中得出最优配置格局.评判结果与地面调查数据基本吻合,为模糊综合评判方法在生态学实践中的应用提供了有力的佐证.

Abstract

Fuzzy overall judgment is applied to evaluate the experimental effects of sand-fixation plant on the water usage efficiency under eight different assemble patterns in Shapotou area. Firstly, the functions of membership grade of soil water are constructed at different layers. Then, weighted coefficients due to the root distributing range are given. Finally, water usage efficiency of the two sand-fixation plants, Artemisia ordosica Krash and Caragana korshinskii Kom, are sorted and evaluated. From which, the ...
