Embodiment 1

[0040] By taking the selection of the optimized combination scheme of the sponge city LID measures in the construction of a sponge city in a certain area of ​​Shenzhen as an implementation case of the present invention, this implementation case is implemented on the premise of the technology of the present invention, and provides detailed implementation methods and details operation process, but the scope of application of the present invention is not limited to the following implementation cases. This implementation case is an example of the optimization evaluation process of the best combination of LID measures for sponge cities. The specific process of this implementation case includes the following steps:

[0041] Step 1: Establish a comparison and selection system for individual sponge city LID measures.

[0042] Through the use of single sponge city LID measures, the analysis is carried out in terms of technical (A1), economic (A2) and social benefit (A3) indicators. T...

Abstract

The invention relates to a sponge city LID measure optimal combination optimization evaluation method based on TFN-AHP method, which belongs to the research technical field of sponge city measure evaluation method. This method first establishes a single sponge city LID measure comparison system, uses the AHP to establish a multi-level index system for different combinations of sponge city LID measures, and uses triangular fuzzy numbers to construct a judgment matrix to determine the weight of each layer of indicators, and then determine the relative importance of each index. The weight of the overall goal, and finally determine the comprehensive weight, so as to obtain the optimal combination optimization of the sponge city LID combination measures. This method has obvious advantages when the system structure is complex and the system cannot be quantitatively analyzed. At the same time, the evaluation method of different combination measures can also be used It has good versatility in other evaluations except the combination optimization of sponge city LID measures.

Description

technical field [0001] The invention belongs to the technical field of sponge city measure evaluation method research, in particular to a sponge city LID measure optimal combination optimization evaluation method based on fuzzy hierarchical analysis. Background technique [0002] Due to the relatively late start of sponge city construction in China and relatively weak technology; however, there are relatively few studies on different combinations of low-impact development technical measures (LID) for sponge city construction, and different technologies are used in domestic planning and design. There is no uniform and effective evaluation method for combined measures, resulting in the lack of scientificity, effectiveness, rationality and economy in the use of technical measures. The best combination optimization evaluation through different combination optimization of different single technical measures of sponge city refers to the selection of the best combination optimizati...
