我国内陆干旱、半干旱地区一般是指年平均降水400mm以下的西部地区,在行政区划上主要包括新疆、青海、甘肃、宁夏、陕西、内蒙古和西藏七个省区的绝大部分地区。这七个省区的土地面积547.5km~2,占全国57.0％;1990年人口10319万人,占全国9.1％,但国民生产总值(当年价)1299.53亿元,只占全国7.4％。如何针对具体实际制定我国内陆干旱、半干旱地区区域开发战略,促进区域经济与社会发展,尽快缩小与发达地区的日异扩大的差距,这是区域开发研究中的重要课题。
Inland arid and semi-arid areas generally refer to the western areas with an annual average rainfall of 400 mm or below. Most of the administrative divisions include Xinjiang, Qinghai, Gansu, Ningxia, Shaanxi, Inner Mongolia and Tibet. The seven provinces and autonomous regions have a land area of 547.5 km2, accounting for 57.0% of the national total. In 1990, the population was 103.19 million, accounting for 9.1% of the national total. However, the GNP (current price) was 129.953 billion yuan, accounting for only 7.4% of the national total. How to formulate a regional development strategy for the inland arid and semi-arid regions in our country, promote regional economic and social development, and narrow the gap between Japan and the developed regions as soon as possible is an important issue in the study of regional development.
