摘要

根据宁南山区典型小流域土地利用现状和相关雨水集蓄资料

计算了彭阳王洼小流域雨水资源潜力

结合小流域节水农业发展规划

对雨水资源开发利用潜力及其供需关系进行了初步评价。结果表明:(1)示范区雨水资源最大理论潜力为7682598m

就地利用、异地利用和叠加利用3种利用方式的比例分别为50.96%

7.16%和41.88%。(2)示范区雨水资源可实现潜力量为7164885m

占全流域雨水资源理论潜力的93.26%。(3)目前示范区小流域的需水总量为3739352m

仅占可实现供水量的52.19%

从示范区小流域雨水资源的可实现潜力来看

还有较大的开发利用潜力。(4)示范区小流域雨水资源利用评价结果表明小流域所制定的雨水利用规模对雨水资源的利用还很不充分

应适当地扩大雨水就地利用规模。

Abstract

After estimating the potential resource of rainwater in Wangwa watershed in Pengyang County

the relationship between its potential and supply was appraised based on the development programmer of water saving agriculture and actuality of land use and rainwater data in the watershed. The results showed that: (1) the potential of theoretical resources of rainwater was 7682598 m3

the ratio of using in the same spot

different spot and rainwater collection reiterative utilization is 50.96%

7.16% and 41.88% respectively. (2) Potential of realistic rainwater was 7164885 m3

which was 93.26% of the potential of theoretical resources. (3) the demand of water in demonstration area was 3 739 352m3

just was 52.19% of the potential of theoretical resources

the remain of Potential of realistic rainwater could be used. (4) the result on assessment of rainwater using in the watershed suggested that the scales of rainwater using was insufficient

so it should be a efficient approach of rainwater resources to enlarge the scales of rainwater using in the same spot.
