贵州喀斯特山区雨洪资源高效利用方法——以普定县陈家寨喀斯特石漠化示范区为例

Efficient Utilization Method of Stormwater Resource in the Karst Mountain Area in Guizhou Province——A Case Study of Chenjiazai Karst Rocky Desertification Demonstration Zone in Puding County

以普定县高羊地下河流域陈家寨石漠化示范区为例,从区域水文地质概况、缺水成因及不同的地形,地貌和土地分布散乱等特点,提出喀斯特山区雨洪资源高效利用的5种方法,有效解决了示范区200亩旱作特色农业、100亩中药材和200亩特色经果林的灌溉用水。因地制宜、因水制宜拦蓄雨洪资源,雨洪资源化,对有效解决喀斯特山区旱作农业生产用水及旱作产业的提升和产业结构的调整具有一定的意义。这5种雨洪资源高效利用的方法可为类似其他喀斯特山区水资源的开发利用提供借鉴。

Considering the characteristics of the regional hydrogeological profiles,the causes of water shortage,the different terrain,the different landscape and the land distribution scattered,the author proposed five types of efficient utilization stormwater resource in the Karst mountain area by taking Chenjiazai rocky desertification demonstration zone of Puding Gaoyang underground river basin as an example. The irrigation water of 500 acres dryland featured agriculture and 200 acres characteristic economic fruit forest in demonstration zone could be efficiently solved. It has meaning to resolving the problems of process water of dryland agriculture,promoting the industry of dryland agriculture and adjusting the industrial structures by storing stormwater resources and utilizing stormwater resources reasonably according to local conditions and water conditions. These five types of efficiently utilization of stormwater resource can provide reference for other similar Karst mountain areas on the development and utilization of water resources.
