Embodiment

[0034] Example: Assuming that the Three Gorges Reservoir Area has 2 ecological adjustment dams to evaluate the necessary degree of construction, dam 1 and dam 2 .

[0035] Through fishbone diagram analysis, the key factors for the construction of ecological regulation dams are found. A 1 =[b 1 ,b 2 ], b 1 is the degree of urgency to control the water-fluctuating area, b 2The ecological condition is the feasibility level of dam construction.

[0036] Dimension b of the urgency of governance in the water-fluctuating zone for key factors through the fishbone diagram 1 Perform feature analysis. B 1 =[c 1 ,c 2 ,c 2 ,c 4 ],c 1 is the spatial relationship between the sinking area and the important area, c 2 improve needs for the environment, c 3 Improve demand for urban quality, c 4 is the need to eradicate poverty.

[0037] According to the fishbone diagram, according to the key factors, ecological conditions, the feasibility degree dimension of dam construction b ...

Abstract

The invention provides a method for quantitatively evaluating the necessary degree of ecological regulation dam construction, which comprises the following specific steps of: searching key elements ofecological regulation dam construction, and searching an ith dimension element and a jth element as cj through fishbone diagram analysis; primarily selecting alternative indexes of each element; quantifying each index; constructing a judgment matrix, and determining an index weight W by adopting an analytic hierarchy process; sequentially calculating each element value based on the index vector and the weight vector of the index vector; sequentially calculating each dimension value based on the element vector and the weight vector thereof; and calculating a necessary degree value of ecological regulation dam construction based on the dimension vector and the weight vector thereof. According to the method, the construction necessity degree of the adjusting dam can be evaluated in a quantitative mode, and the method is more scientific and comprehensive.

Description

technical field [0001] The invention relates to the field of reservoir water-fluctuation zone control, in particular to a method for quantitatively evaluating the necessity of ecological regulation dam construction. Background technique [0002] Reservoir drawdown area management is still a world-class problem. Bank slope plants suitable for the 30m height of the Three Gorges Reservoir and capable of effectively controlling the drawdown area have not been found, and hard slope protection is not suitable for large-scale adoption. The combination of ecological adjustment dams and biological measures is currently the most effective and feasible plan for the treatment of tributary drawdown areas with flat terrain, large areas and prominent ecological and environmental problems around cities and towns. This scheme has good ecological, environmental, economic and social benefits, but it also has the problem of encroaching on the flood control storage capacity of the Three Gorges ...
