宁夏南部旱区农业水资源开发与可持续利用

Sustainable Using for Agriculture Water Resources in the Dry land south of Ningxia

从广义的水资源概念出发 ,分析了宁夏南部旱区水资源的数量、质量和区域分布特征。宁夏南部旱区农业水资源 14 90亿m3 ,占整个区域水资源总量的 93 35 %。其中土壤水资源为6 35亿m3 ,是这一区域旱作农业、草地、林地等农业生产和生态恢复与建设的重要来源。依据该区域水资源现状及开发利用中存在的问题 ,提出了农业水资源可持续利用的若干对策。

Set out from the broad sense of water resources, the quality, quantity and distribute characteristic of agricultural water resources in the dry land south of Niogxia were discussed in the paper.
