摘    要:宁夏中部风沙区的沙质荒漠化在历史时期,尤其是本世纪50年代以来,具有明显扩展的趋势。过度开垦、过度放牧、滥肆樵采、工矿建设等人类活动对这一地区荒漠化的发展起了推动作用。对研究区域的经济结构、生产要素和经济行为3个方面分析认为,落后的产业结构和低劣的生产要素既是被动适应地理环境的结果,又成为导致人类不良经济行为和以牺牲地理环境为代价来求得生存发展的原因,防治荒漠化不应忽视通过改变现有经济结构、生产要素等途径和运用经济杠杆等手段规范人类活动。

关 键 词:宁夏中部风沙区  沙质荒漠化  人类活动  经济分析

Abstract:There is an obvious developing tendency of sandy desertification in the blowing sand region of middle Ningxia in historical time, especially since 1950's. Human activities have promoted the development of desertification in the region through over cultivating, over grazing, over exploitation and denudation, and construction of manufactures and mines. Analysis on the economic structure, essential productive factors and economic activities in the studied area proved that the backward economic structure and inferior productive factor are not only the results of passively acclimatizing the geographical environment, but also the reasons that lead to the irrational economic activities and the sacrifice of geographical environment in order to survive and develop. Finally, the paper suggests that it must pay great attention to standard human activity through transforming present economic structure and productive factor and using economic means in preventing and harnessing desertification.
Keywords:the blowing sand region in middle Ningxia  sandy desertification  human activity  economic analysis
