我国西部地区特别是西北地区的水资源问题,是制约经济和社会发展的一个重要因素。西部缺水类型多样西部水土资源分布不均衡,相对来说,西南地区水多土少,西北地区土多水少,降雨的年际和年内季节的分布很不均匀,旱、涝、洪、碱、污染在不同地区交替出现。社会和经济发展在很大程度上受到水利问题的制约。因此,解决水资源短缺与浪费、水资源污染问题,既是当务之急,也是战略性问题。加快西部的水利基础设施建设,是加快西部大开发的一个重要组成部分,是涉及西部发展全局和改善生态环境的重大问题。因此,要把水资源的合理开发和利用放到突出位置,从实际需要和可行性出发,并针对目前存在的突出问题,对水利建设统筹规化分步实施。目前西北大部分地区和西 The issue of water resources in the western region of our country, especially in the northwest region, is an important factor that restricts economic and social development. In western China, the water and land resources in the western region are unevenly distributed. Relatively speaking, the water in the southwest is less, the soil is less and the water in the northwest is scarce, and the distribution of rainfall interannual and annual seasons is uneven. Drought, waterlogging, flood, alkali Pollution occurs alternately in different regions. Social and economic development is largely constrained by water issues. Therefore, solving the problems of water shortage and waste and water pollution is not only a top priority but also a strategic issue. Accelerating the construction of water conservancy infrastructure in the western part of our country is an important part of accelerating the large-scale development of the western region and a major issue that involves the overall development of the western region and the improvement of the ecological environment. Therefore, it is necessary to put the rational development and utilization of water resources in a prominent position, proceed from the actual needs and feasibility, and implement the overall plan for water conservancy construction in light of the outstanding problems that currently exist. Most parts of the northwest and west
