黄淮海地区农业节水对策及实施半旱地农业可行性研究

Study on agricultural water-saving countermeasures and feasibility of implementing semi-dryland farming in the Huang-Huai-Hai Region

通过系统调研,从挖掘各类农业水资源潜力入手,分析总结了黄淮海地区农业节水的成效、经验与存在的问题,认为在充分利用降水基础上实施补充少量灌溉水的半旱地农业是解决该区域水资源严重短缺,同时实现农业生产可持续增长的一条重要出路。旱地农业、灌溉农业和半旱地农业并存将成为未来农业用水的新格局,按此对策实施,预期到2020年,该地区农田灌溉用水量可减少30%以上,并率先实现农业用水系统的现代化。

Starting from fully excavating the potential of various agricultural water resources in the Huang-Huai-Hai Region,the achievement,experience and existing problems about agricultural water-saving were summarized.It was proposed that by implementing semi-dryland farming,developing simultaneously irrigated lands and dry lands on the basis of full utilization of local natural rainfall,and saving the large amount of irrigation water is an important approach for resolving serious water resources shortage and meanwhile for achieving sustainable growth of agricultural production in this region.Dryland farming,irrigated farming and semi-dryland farming will exist at the same time as the new structure of agricultural water use in this region.By implementing these measures,field irrigation water consumption in this region is expected to reduce more than 30 % in around 2020 and take the lead in realizing the modernization of agricultural water system.
