摘要
近年来,由于降水时空分布不均,加之人们对水资源的不合理利用等原因,湖南省的农业干旱灾害不仅发生频率高、灾情重,而且具有明显的连季性和连年性,这严重制约该省农业的可持续发展。要从根本上缓解该省的农业旱灾,实现洪水资源化是一条重要的举施,且基于投入产出分析,主要作好4个方面的工作:更新改造与兴建扩建一批水利工程,增大供水量;加强山丘区工程与生物措施的结合,以提高洪水资源率;科学调度大型水库,蓄足洪水资源;利用地下水回灌及实施水系联网工程,增加可用水资源和实现洪水资源化。
The agricultural disasters of drought in Hunan Province past years consist of not only frequently and seriously but also successively cause crops failure due to the uneven distribution of rainfall plus unreasonable use of water resources. Thus it restrains the sustained agricultural development in this province. In case to relief the agricuhural disasters of drought, the important action si to become the deluge resources into natural resources which should be cotrolled and managed properly. The main four aspects should be done as follows on the basis of analysis of investment and production. （a） To renew, construct and reconstruct a batch of water conservancy projects with enlarging water supply; （b） To raise the use ration of floodwater resources by means of combination with hill water irrigation project and biological engineering; （c） To manage the water resources in large reservoir which keeps more water; （d） To make use of underground water to be as back irrigation and water conservancy irrigation being network, to increase water resources and making the flood water as natural resources.
