Embodiment 1

[0035] see Figure 1-4 Shown is a specific embodiment of the rainwater collection and flood storage and tree planting channel in the arid area described in the application. The rainwater collection and flood storage and tree planting channel in the arid area includes: catchment slope 1, erosion channel 2, water retention dam 3, and water storage pit 4, of which,

[0036] The catchment slope 1 is located on both sides of the erosion channel 2, and surface runoff can be generated during rainfall or when the ground snow melts. The catchment slope 1 is used to collect the surface runoff formed by rainwater and snowwater into the In the erosion channel 2;

[0037] The erosion channel 2 is formed by the erosion of natural rainwater. It is located in the middle of the catchment slope 1 on both sides and developed below the ground. It is used to store the rainwater and snowwater collected by the catchment slope 1. The gathering place of runoff and snowmelt water; the slope α of the ...

Embodiment 2

[0043] On the basis of embodiment 1, continue to refer to Figure 1-Figure 4 ,as well as Figure 5 , the present application further provides another embodiment of the tree-planting channel for rainwater collection and flood storage in arid areas.

[0044] The slope α of the catchment slope 1 2 is 9° to 45°, and the slope length a of the catchment slope 1 is greater than or equal to 10m to ensure that a certain volume of rainwater is collected into the erosion ditch 2 in the form of surface runoff during erosive heavy rainfall.

[0045] The width b of the erosion trench 2 is 0.5m to 10m, and the depth h of the erosion trench 2 is 1 is 0.2m to 10m, and the length c of the erosion channel 2 is greater than or equal to 10m; it usually refers to a shallow ditch and a cut ditch. The rill, that is, the shallow trough (0.5 meters wide, 0.1m to 0.4m deep, and several meters long), is further cut and deepened by the rill to form a cut groove.

[0046] Described retaining dam 3 is e...

Abstract

The invention discloses an arid-region rainwater-collection flood-storage tree planting ditch. The arid-region rainwater-collection flood-storage tree planting ditch comprises water collecting slope surfaces, an erosion ditch, water retaining dams and water storage pits, wherein the water collecting slope surfaces are positioned at the two sides of the erosion ditch for collecting direct surface runoff formed by rainwater and snow water into the erosion ditch; the erosion ditch is formed by natural rainwater scouring, and is used for storing rainwater and snow water collected by the water collecting slope surfaces; one water retaining dam is arranged in the erosion ditch every predetermined distance for blocking upstream coming water of the erosion ditch; one water storage pit is formed inone side, towards the upstream coming water of the erosion ditch, of each water retaining wall for storing upstream coming water; a plurality of tree seedlings are planted in each water storage pit;and a groove can be formed in the middle part of the upper bottom of each water retaining dam. The ditch eroded by natural rainwater is used to block and store direct surface runoff generated during rainstorm, and the water retaining dams are utilized for blocking and storing most of direct surface runoff in the ditch, so that the risk that the ditch downstream flood damages occur is weakened. Accumulated water in the water storage pits is used for growth and utilization of tree seedlings, so that greening of barren mountains and gullies is realized.

Description

technical field [0001] The invention relates to the technical field of utilization of rain and flood resources in arid areas, in particular to a tree-planting ditch for collecting rain, storing floods and planting trees in arid areas. Background technique [0002] Generally, areas with annual precipitation below 200mm are called arid areas, and areas with annual precipitation between 200-500mm are called semi-arid areas. The generally studied arid area (abbreviated as arid area) is the general term of the two. Due to the drought and lack of rainfall, the vegetation in the arid area is sparse and the ecological environment is relatively fragile. In the context of climate change and uncertainty, extreme heavy rainfall events are increasing, and dry areas are facing serious problems such as soil erosion, torrential rain and floods. Short-term rainstorms and floods cannot be utilized as resources, resulting in waste of water resources. [0003] The rain harvesting technology ...
