中国西南地区农业水资源利用现状及对策

西南地区总体上虽然水资源丰富，但其时空分布不适宜于农业生产。很多灌溉设施不能正常工作。与此同时，大量的水资源在灌溉过程中被浪费掉。因而一遇干旱，这一地区便常常缺水。这对农业生产乃至农民生活构成严峻威胁。本文分析了这一地区水资源及其在农业上的利用以及农业灌溉系统的现状，提出了节水灌溉与农业产业化相结合，集成相关技术、措施与政策，加强节水领域的研究与开发工作、加快建设水利基础设施与平整土地，开发和应用适用技术以及建立良好的法规政策体系等对策。

Status of water use in agriculture and strategies on water-saving irrigation in Southwest China

Water resources in southwest China are generally abundant, but its temporal and spatial distributions are not suitable to agricultural production. And many irrigation projects there have gone wrong. At the same time, a lot of water is wasted during irrigation, so there is usually a water shortage when the drought comes. This poses a grave threat to agricultural production and even to farmer's daily life. The current situation of agricultural water resources, utilization of water in agriculture and irrigation system in Southwest China was analyzed and strategies on water saving in agriculture, such as a combination of water-saving and agricultural industrialization, integration of relevant technologies, measures and policies, enhancement of R and D in water-saving, strengthening the construction of basic watering facilities and leveling fields, development and application of appropriate technologies and establishment of a good system of laws and policies were put forward in this paper.
