黄土高原地区地下水资源农业利用历史演变特征研究

地下水的合理利用是农业可持续发展的重要前提。运用历史演进的方法,研究了历史时期黄土高原地区农牧业占用地下水的分布状况,归纳出地下水农业利用历史演变的特征。即:(1)人类对地下水的利用随社会生产力水平的提高、农牧业活动范围的扩大而趋于复杂化和多类型化;(2)地下水农业利用的深度和广度与当时生产力水平密切相关,生产力水平的高低是决定黄土高原地区地下水农业利用程度与方式的主导因素。

Historical development of undergroundwater harness for agriculture in Loess Plateau

Reasonable use of groundwater is important to sustainable develo pm ent of agriculture. This paper studied the occuping situation of agriculture and pastry to groundwater factors in history of Loess Plateau by using a metho d of historical developement. Two characters have been found: Firstly, the harn ess of groundwater tended to become complex and diversified along with the prom otion of productive level and the extension of agricultural and pastral activi ties of human being; Secondly, the depth and width of groundwater use in agric ulture have a close relation with productive force, the change of which is a key factor in determining groundwater use degree and model in Loess Plateau.
