河西内陆河流域的水循环特征

The Features of Water Cycle in Inland River Basins in Hexi Region

本文主要从分析我国西北内陆水循环主要环节出发,揭示河西内陆河流域水循环在山区形成水资源、在平原散失水资源和在人工绿洲产生水循环二元结构、以及水量相互转化和联系的特征;对山区消耗水量,走廊盆地人工绿洲建设引起的地表水与地下水转化的变化及其消耗水量的增加,以及下游水分亏缺等问题作了评价;还对山区与平原绿洲及其之间的局地水循环,西部开发实施黑河和塔里木河综合治理中实现良性循环和传递流域水循环整体概念等问题进行了讨论。

This paper revealed the formation of water resources in mountain areas, the scatter and disappear of water resources in plain areas and the duality composition in artificial oases and revealed their water transformation features and relationship each other in the water cycle of inland river basins of Hexi Region mainly through analysis of key links in the water cycle of the interior region in Northwest China. Water consumption in mountain areas,transformation between surface water and ground water and consumption increase caused by artificial oases construction in the Hexi Corridor, and water shortage of down streams in inland river basins were also evaluated. Discussions of evaluating local water cycles between mountain and plain areas, achieving a virtuous cycle in comprehensive rehabilitation of Hei River and Tarim River of the West-China development and delivering entire concept of water cycle in a river basin were put forwards finally.
