在开发大西北中,我们面临水资源短缺的挑战,本文针对西北干旱区水资源特征、水资源利用对环境影响的分析,提出通过制定流域合理开发模式、加强水利管理、建立合理灌溉制度、按方收费、推广先进灌水技术、控制潜水临界深度、整治河道、取缔病库、培育耐旱作物等措施,减少水体蒸发和渗漏的部分损失,提高水的利用率,增加单位水体的效益,这是维持西北干旱区水资源与生态平衡的关键。
In the development of the northwestern China, we are faced with the challenge of water shortage. In this paper, according to the characteristics of water resources and the impact of water resources on the environment in the arid region of Northwest China, this paper proposes that by formulating the rational development of watershed, strengthening water management and establishing a reasonable irrigation system, Side charges, promotion of advanced irrigation technology, control of the critical depth of the submersible, river regulation, banning the disease library, cultivating drought-resistant crops and other measures to reduce water evaporation and leakage of some of the losses, improve water utilization and increase the benefits of water bodies, This is the key to maintaining water resources and ecological balance in the arid region of northwestern China.
