摘要
干旱半干旱地区雨水资源潜力巨大,蓄雨用水是解决干旱缺水,提高作物生产潜力,发展旱区高效农业的重大举措。因此,大力开发利用雨水资源是解决该地区农业缺水的主要途径,这也是区域农业持续发展的战略性问题。分析雨水高效利用的几种途径,主要包括:雨水就地入渗,雨水的叠加利用和雨水的聚集利用技术,其中雨水聚集利用是干旱半干旱地区农业生产中雨水利用的最主要形式。提出了雨水利用系统中在雨水径流集聚技术、降雨聚集利用技术和高效利用等方面存在的一些主要问题,以及降雨聚集利用系统需要研究解决的一些关键技术问题。
The rainfall resource has a great potential in arid and semiarid areas. Water harvest is an important measure for solving water shortage, increasing crop yield, and developing high efficient agriculture in dry areas. Therefore, the development and utilization of rainfall resources is a main way to solve agricultural water stress, which is also important to develop sustainable agriculture. Several methods for high efficient use of rainfall, which include infiltration of rainfall on the spot, utilization of piling up rainfall, and utilization of rainfall harvesting, have been discussed. The utilization of rainfall harvest is the main method of rainfall utilization in agricultural production. Some problems have been raised in rainfall harvest techniques, utilization techniques, and high efficient use. Some key technical problems that need to be solved in the utilization system of rainfall harvest have also been raised.
