Water conservationr Taojia River comprehensive treatment method fo

Abstract

The invention belongs to the technical field of environment protection and discloses a water conservation comprehensive treatment method for Taojia River. On-the-spot investigation is conducted on theTaojia River, overall consideration is conducted in combination with factors such as the debris flow development situation, loose solid matter and the like, and the check dam engineering, the bed fixing dam engineering, the sediment storage dam engineering design, the drainage and guiding groove engineering and the water channel anti-seepage reinforcing engineering are calculated according to water and soil conservation and water conservancy and hydropower engineering quantities; slope surface treatment, water and soil conservation forestation and economic and fruit frost cultivation are conducted; manual enclosure for recovering vegetation is conducted on barren mountains and slopes remaining after water and soil conservation forestation, land difficult to utilize and part of sparse andyoung plantation inside a drainage basin; and the soil conservation tillage measure is taken for cultivated land on gentle slopes, and the ridge plant protection measure is taken for cultivated land on abrupt slopes. By means of the water conservation comprehensive treatment method, the water and soil loss amount is obviously reduced; safety of villages, water conservancy projects, traffic facilities and farmland is effectively protected; and on the basis that the ecological environment, the slope cropland tillage conditions and the farmland water conservation facilities are improved, water and soil resources are developed and utilized, and the economy is developed so that the living standard of local people can be raised.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a comprehensive water and water conservation treatment method for Taojiaxiao River. Background technique [0002] Taojia Xiaohe is located in the south of Dongchuan District, Yunnan Province, with an east longitude of 103°14′24"~103°21′36" and a north latitude of 25°57′22"~26°01′35", with a basin area of ​​71.16km 2 , the main ditch is 16.6km long, originating in Jiache Township, Huize County, Yunnan Province, belonging to the Xiaojiang River Basin of the Jinsha River System, flowing into the Dabai River, an eastern tributary of the Xiaojiang River from east to west. Goukou is 20km away from Dongchuan City. The highway from Kunming to Dongchuan passes through Goukou, and the railway branch line from Kunming to Dongchuan passes through the west bank of the confluence of Taojiaxiao River and Dabai River. The dam is located on the main channel of the Da...

AI Technical Summary

Problems solved by technology

[0003] In summary, the existing problems in the prior art are: the soil erosion in the Taojia Xiaohe Basin is serious, and landslides and debris flow disasters are more, resulting in the loss of cultivated land water, soil, and fertilizer, low unit yield, landslides and avalanches, and increased difficulty in artificial afforestation. The vegetation recovery rate is lower than the growth rate of water and soil erosion, the level of irrigation and water conservancy is low, the traffic is not smooth, the fuel and feed are lacking, the drinking water for humans and animals is difficult, the farmers live in poverty, and their ecological environment has deteriorated
