摘　　要：以民勤湖区具有代表性的7种生态移民模式为研究比较对象,基于理想解法的模型框架,实地调研、入户走访收集基础数据,并采用一种客观的方法获取权重,建构模型.计算结果表明,研究区正新模式最优,宋河模式最劣.建议西北地区乃至全国生态脆弱地区以正新模式为范例,制定符合本区域实际的移民模式,缓解区域内生态恶化的局面.This article chose 7representative species migration patterns in Minqin lake as the research object.Based on top-sis model,field research,home visits,collecting basic data and using an objective method to get the weight,a model is constructed.The results suggest that the best model is Zhengxin and the worst is Songhe.So we recommended that the ecologically fragile areas in northwest of China could develop a new model in line with actual immigration patterns,to alleviate ecological deterioration of the situation in the region.
