摘  要：
针对宁夏中部干旱带土壤风蚀严重、沙尘暴频发等生态问题,分别选择典型压砂农田、沙质旱作传统翻耕农田、人工灌木林地、封育草场和流动沙地5种风蚀环境为研究对象,利用TOPSIS法综合评价不同风蚀环境抗风蚀性能。结果表明:灌木林地的抗风蚀性能最强,其Ci值为0.674257,其次为压砂农田、封育草场;抗风蚀性能最弱的是翻耕农田、流动沙地,Ci值分别为0.087007和0.003552。可见翻耕农田和流动沙地是当地主要沙尘来源。

摘  要：
Serious soil erosion and frequently occurred sandstorm are main ecological problems in arid zone of middle Ningxia. In order to control these disasters, we chose typical pebbling farmland, traditional tillagefarmland, artificial shrub land, fenced grasslands and shifting sandy land as the research objects, and winderosion-resistance were comprehensively analyzed with TOPSIS method. The results showed that shrub landhad the strongest ability to resist wind erosion, whose Ci was 0.674257. Traditional tillage farmland and shiftingsandy land had relatively weak ability to resist wind erosion, with Ci respectively being 0.087007 and0.003552. So the traditional tillage farmland and shifting sandy land are the main dust sources.
