| 中文摘要: |
| 从集雨农业科学研究的历史、雨水收集蓄存技术、集雨系统的分类、集雨模型和收集雨水的高效利用等方面详述了近一个世纪以来国内外的研究进展情况,指出了目前所存在的问题有:(1)对区域可收集雨水资源潜力的评估与计算研究不够;(2)多注重雨水汇集、雨水蓄存、雨水利用等各单项技术的研究,而没有把它们当作一个整体来进行研究,对这些技术的集成研究不够;(3)重视了雨水集流量的研究,而忽略了雨水集流度的研究;(4)未将生态需水纳入集雨模型。对未来集雨农业研究进行了展望。 |
| 英文摘要: |
| In the world, catching rainwater for agriculture is an effective approach to solve the shortage of agricultural resources and has existed for several thousands of years. The paper expatiates the international advances of rainwater catchment in terms of the history of agricultural rainwater-catching research and the techniques and models of rainwater catchment and storage, the classification of rainwater catchment systems and the high-efficiency use of caught rainwater in nearly one century, and point out the current problems in agricultural rainwater-catching research which are (1) inadequate evaluation and calculation of regional potential rainwater resources, (2) lack of the research that integrates the individual techniques of rainwater catchment, storage, and utilization other than only paying attention to the individual techniques, (3) emphasis on the research of rainwater-catching flux and ignorance of the research of the rainwater-catching intensity, and (4) rainwater-catching models that do not take into account environment water requirements. At the end, the paper also envisages the future of the research of rainwater-catching agriculture. |
