Embodiment 1

[0048] Example 1 (Ecological Restoration Project for the Road Slope of the Guizhou Guangzhao Hydropower Station)

[0049] Project overview: This project is located in the Guangzhao Hydropower Station in Guizhou Province, at the junction of Qinglong County, Qianxinan Prefecture and Guanling County, Anshun City, and belongs to the Beipan River Basin. The climate in this area is three-dimensional, spanning the southern temperate zone, northern subtropical zone, and mid-subtropical zone. 12.5% ​​of the low-heat valley areas in the territory are known as "natural greenhouses". The accumulative annual average temperature is 16.2°C, the annual average maximum temperature is 16.9°C, and the minimum temperature is 15.4°C. The rainfall is abundant, and the annual precipitation is 1205.1-1656.8mm. It is one of the precipitation centers in the province. The newly excavated rock face of the hydropower station is composed of limestone and part of sedimentary sandstone. The slope is steep a...

Embodiment 2

[0064] Embodiment 2 (Ecological Restoration Project of Steep Slope Excavated by the Access Road of Yunnan Xiaowan Hydropower Station)

[0065] Project overview: This project is located in the Xiaowan Hydropower Station of the Lancang River in Yunnan. This area belongs to the subtropical monsoon climate, and the annual rainfall is about 1000-1150mm, of which the rainfall is mainly concentrated in the six months of May, June, July, August, September and October. , early spring and winter are dry and rainless. In a year, the sunshine hours are more than 2000 hours, the annual average temperature is 16-18°C, the coldest monthly average temperature is 8-10°C, and the annual accumulated temperature is 5400°C. The soil is red soil, with a pH value of 5.0-5.8, poor in organic matter and nitrogen; phosphorus is easily fixed, the utilization rate is not high, the soil clay content is high, and it is easy to harden; water-soluble boron, available zinc and copper are relatively deficient....

Embodiment 3

[0085] Embodiment 3 (Ecological Restoration Project of the Excavation Slope of the Approach Road of Xiangjiaba Hydropower Station)

[0086] Project overview: Xiangjiaba Hydropower Station is the most downstream cascade of the main stream of the Jinsha River, and is in the best geographical location of the load center in East China and Central China for the "West to East Power Transmission". The dam site of the power station is located at the exit of Xiangjiaba Canyon on the lower reaches of the Jinsha River. The left bank is Yibin County, Sichuan Province, and the right bank is Shuifu County, Yunnan Province. The drainage area above the dam site of Xiangjiaba Hydropower Station is 458,800 km 2 , accounting for 97% of the Jinsha River basin area, the average annual discharge of the dam site is 4570m 3 / s, the annual runoff is 144 billion m 3 . The runoff is dominated by rainfall, supplemented by ice and snow melt water, and the interannual water volume is relatively stable. ...

Abstract

The invention provides a dynamic feedback adjustment method for integrated evaluation and guidance of artificial regulation of slope ecological restoration by using a slope ecological restoration project. The method comprises: step one, constructing an integrated quality evaluation system of a slope ecological restoration project; step two, recording a final evaluation result as Ax; step three, analyzing a real-time existence problem of a target slope ecological restoration project; step four, studying and determining a problem found out at the step three and selecting a regulation method; step five, formulating a regulation plan; step six, implementing a regulation plane; step seven, recording a final evaluation result as an A x+1; and step eight, comparing the A x+1 with an expected target and implementing the optimized regulation plan step at least once until the final evaluation result reaches the expected target. According to the method provided by the invention, problems of difficult quantitative and qualitative evaluation of the slope ecological restoration project can be solved.

Description

technical field [0001] The invention relates to the field of slope ecological restoration, in particular to a dynamic feedback adjustment method for guiding artificial regulation of slope ecological restoration by using a comprehensive evaluation of a slope ecological restoration project. Background technique [0002] AHP-fuzzy comprehensive evaluation method is a method of organically combining the analytic hierarchy process and fuzzy comprehensive evaluation method to comprehensively evaluate the target object. Comprehensive evaluation method. [0003] Artificial regulation refers to regulation measures that complement natural regulation within the system according to human needs and purposes. Through the artificial design of the damaged ecosystem, human-led, under the guidance of the principle of co-creation between man and nature, the structure is repaired and perfected to achieve the purpose of restoring the ecosystem. For example, irrigation is a supplement to precip...
