摘要
西部开发区范围大 ,占国土总面积 71.4% ,人口占全国的 2 8.1%。由于它们之间自然生态条件和人文社会经济发展水平相差悬殊 ,生态环境的保护、建设及开发内容和目标不一样 ,因此应划分区域进行开发建设 .共划分出 5个亚区 :1小西部亚区 ,包括内蒙古、宁夏、甘肃、青海和新疆 5省区 ;2黄河中游黄土高原亚区 ,开发区内仅陕西 1省但应和山西共同开发治理 ;3西南亚区 ,包括广西、贵州和云南 3省区 ;4重庆四川亚区 ;
The Western Development Region of China is large in area, making respectively 71.40 percent of the total national land area and 48.89 percent of the total national population. In this region, a remarkable difference exists in the natural ecological conditions as well as in the social and economic status. Accordingly, the need arises to vary the ecological preservation and development items and objectives in different geographic areas. In this article, five sub regions are designated for that purpose, namely, the Lesser West Sub region consisting of Inner Mongolia, Ningxia, Gansu, Qinghai, and Xinjiang; the Loess Sub region along the middle reaches of Yellow River with only Shaanxi that is supposed to be environmentally jointly developed and controlled with Shanxi; the Southwest Sub region of Guangxi, Guizhou, and Yunnan; the Chongqing Sichuan Sub region; and the Cold Xizang(Tibet) Plateau Sub region.
