Method for using flood in dry land

Abstract

The invention relates to a method for using flood in dry land. A fixing belt and a buffer layer belt of the green plants are built on the upstream face of an earth dam; at least one cellar is dug in the intercepting area formed by the earth dam; a layer of planting bed is set in the intercepting area; a planting basket is installed on the planting bed; the soil with seeds is filled in the planting basket; the flood can be stored in the cellar; when the soil is dry, the plants in the fixing belt and planting basket of the green plants are sprayed by pumping. The method can use the flood in the sol transformation of the dry land effectively and solve the problem of serious water and soil loss of the dry land; the method is designed according to the special landform of the dry land; a new concept is provided for comprehensive utilization of silt arrester and water resource in the dry land; and the exploitation and utilization of the flood resource is in a new height.

Description

technical field [0001] The invention relates to a dryland flood utilization method. Background technique [0002] The arid areas in northern my country are short of water due to drought, and with the erosion of floods, soil erosion is caused, resulting in a large waste of water and soil resources. Flood resources are the largest water resources in drylands. If the flood resources in drylands can be rationally utilized and developed, it will be of great significance to the dryland mountainous areas. [0003] In the prior art, the reports on flood utilization methods in dry land have been documented, for example, in "A Preliminary Exploration on Utilizing Water Storage Facilities to Develop Warping Dam Water Resources" (Water Conservancy Economics, Volume 22 No. 6, November 2004), the Warping dams are combined with storage tanks, water cellars and other water storage facilities, and the use of check dams to collect rainwater on large slopes and store water through storage tan...

AI Technical Summary

Problems solved by technology

[0004] But the above method has the following defects: 1. The inlets of water storage facilities are small and small in number, which may be blocked by floating objects, resulting in failure to store water normally; 2. The silt formed by the blocking of the dam body is only surface deposition, and cannot form real usable land; 3. Existing water storage facilities use the same outlet for desilting and drainage, and the effect of desilting is not ideal and cannot be effectively discharged, causing the facilities to fail to work normally and costing a lot of maintenance
