中文摘要：

生态移民工程是实现生态环境脆弱区环境-经济-社会可持续发展的重要举措。文中以宁夏生态移民为例,从移民视角出发构建社会适应性研究框架,分别从经济生产、生活方式、人际关系三个方面分析不同年龄层次移民的社会适应性规律。探讨分析影响不同年龄层次移民适应因素,并通构建优化策略模型提出相应的适应策略。研究表明：在生活方式和人际关系方面适应性普遍较强、年龄层次差异小;在经济生产方面适应性普遍较差、年龄层次差异性较大。其中31-40岁移民适应性较强且适应优化模型各方面都比较高;18-30岁移民适应性及优化模型各方面适中;41-55岁年龄层次的移民适应性相比较最弱,适应优化模型各方面也较差。

英文摘要：

In this research, from the view of different age levels, adaptation of ecological immigrants in Ningxia was analyzed, Which is not only the innovation of theory but also can provide a basis for the implementation and development after the relevant immigration policy. Ecological migration was conducted better in Ningxia and developed well. Taking Xinrong, Yuanlong and Heshun Villages as the study areas, ages of immigrants were divid- ed into four levels： 18 -30 years old, 31 - 40 years old, 41 -55 years old and 55 years above . The research got following conclusions： firstly, life style and interpersonal adaptability were better, and age difference was small. Secondly, the economic adaptability was generally poor, age differences was bigger. The 18 -30 age levels of immigrants had better adaptability, adaptability of 31 - 40 age level of immigrants was moderate, adapta- bility of immigrants over the age of 41 were weaker.
