摘要
根据1983～1986年的野外试验结果,运用TOPSIS决策方法得到不同植被水土保持效益的大小依次为沙打旺,紫花苜蓿,紫花苜蓿+洋芋,草木樨,沙打旺+双青豆,草木樨+谷子,水平沟谷子,普种谷子,沙打旺+谷子,普种洋芋,TOPSIS决策法具有准确的多目标综合评价能力,宜在农牧生产和水土保持的效益评价研究中推广应用。
Using the TOPSIS decision—making method, the order of soil and water conservation benefit of some plant species can be obtained. The result showed that the order was: Astragalus adsurgens Pall. >Medicago satwa Linn. >Medicago sativa Linn. +potato>Meliotus officicalis(L.) Desr.>Astragalus adsurgens Pall. + legumes>Meliotus officicalis (L.) Desr. +millets>horizantal furrow millets>ordinary breeding millets Astragalus adsurgens Pall. +millets>ordinary breeding potato>barren land. TOPSIS algorithm has the comprehensive ability for different objectives, and has the characteristic of precise results, so should be popularized for application in benefit—estimating field.
