Abstract

The invention discloses a Karst sloping field efficient water collection irrigation method and an irrigation system. According to the method, water storing facilities are arranged on the upper part, the middle and the lower part of a mountain and are respectively used for collecting sloping surface rainwater in the upper part of the mountain, surface layer karst spring water in the middle of the mountain and road surface rainwater in the lower part of the mountain, and water storing facilitates are arranged in field land parcels to be irrigated on the whole mountain slope surface; the water storing facilities in the upper part, the middle and the lower part of the mountain and the water storing facilities in the field land parcels are interconnected by pipelines to realize the efficient water collection irrigation of the whole mountain slope surface. On the basis of the whole slope surface visual angle, water collection begins in the slope top, different types of water resources of the upper part, the middle and the lower part of the mountain are integrated and efficiently utilized, the use efficiency of rainwater resources is greatly improved, the irrigation requirements of the whole slope surface are met, the irrigation difficulty of the large-area slope surface is solved, the slope runoff and the sediment amount are effectively reduced, and the erosion to slope surface soil by rainwater is avoided.

Description

technical field [0001] The invention relates to a method and device for developing and utilizing rainwater resources, in particular to a high-efficiency water collection irrigation method and an irrigation system for karst slope land. Background technique [0002] In the karst area of ​​southern China centered on the Guizhou Plateau, karstification is strong, the two-dimensional three-dimensional spatial structure is developed, the surface water capacity and regulation ability are low, and the rainfall quickly flows into the ground along the fissures, funnels, sinkholes, and slopes lacking soil and forests. And deep valleys, water and land resources do not match. Water shortage has always been the bottleneck restricting the socio-economic development of the region. In recent years, the state has implemented a series of major water conservancy and soil conservation projects, which have achieved good results in solving the problem of centralized drinking water in cities and i...
