南水北调中线供水区水资源特性分析

Water resource characteristics in riparian region of middle route S-to-N Water Transfer Project

南水北调中线供水区的工农业生产在我国占有重要地位，唯水资源不足制约工农业的发展。本文根据供水区各省（市）提供的水资源评价资料，对中线供水区水资源量及其时空公布规律进行了分析评价。在此基础上，对供水区主要水资源特性和问题进行了分析。结果表明，中线供水区水资源较为匮乏，急需从外流域引水补源。

The industry and agriculture production in the riparian region of the middle route S-to-N Water Transfer Project plays an important role in China, but its regional development is restricted by water resource deficit. Based on water resource evaluation data provided by riparian provinces(or cites), this paper has analysed and evaluated the amount of water resource and its time-regional distribution in this water deficit region. The major characteristics and problems of water resource of this region are also analysed.The results demonstrated that this region's water resource is far from enough and some extra water from other watershed is needed for supplying this region.
