中文摘要：

本文通过选取的水资源总量、年沙尘暴天数,耕地面积,年平均降水量和年平均温度等因子,作为判断典型干旱区PRED系统状况的生态环境指标。并结合国民生产总值,总人口数量,恩格尔系数等其它因子来讨论新疆民丰县PRED系统的发展过程。结果表明这些生态环境指标用于评价工业不发达,生态环境脆弱的典型干旱区,能较好地反映其在时间序列上的发展状况和实际的区域协调发展,为其建设发展提供了评判和规划的依据。

英文摘要：

To most countries and towns in arid region, entironment is the factor that restricts their economic development. This research takes total amount of water resources, annual days of sand-dust storms, cultivated area, annual average precipitation and annual average temperature as the environment indexes to estimate the status of typical arid region＇s PRED system. The developing process of PRED system in Xinjiang Minfeng country was discussed combining GNP（Gross National Product） ,total population, Engle coefficient and other factors. The results indicated that these environment indexes could preferably reflect its development status in time sequence and actual regional compatible development when evaluating typical arid regions with underdeveloping industry or fragile fragile entironment. Therefore fundamental basis for judging arid programming its construction and development were provided.
