The invention relates to a screening method of source emission reduction technology in urban low-impact development technology, which belongs to the field of urban planning technology. It solves the problem that the traditional low-impact development source emission reduction technology plan requires human experience to judge and select the source emission reduction technology, which is inefficient and subjective, and the choice of technology cannot take into account control objectives, costs, efficiency, benefits and other indicators. The invention establishes a low-impact development source emission reduction technology screening index system; according to the alternative technologies and index items, establishes an alternative technology scoring database, performs matrix conversion on each scoring table in the database, and constructs a decision matrix for each scoring table; calculates The fuzzy distance between each decision matrix and the positive and negative ideal technical solutions; calculate the relative closeness between the decision matrix and the positive and negative ideal technical solutions; calculate the comprehensive score of the alternative technologies; sort the alternative technologies according to the comprehensive scores of the alternative technologies, Complete the screening of emission reduction technologies at the source. The invention is applicable to urban planning.
Description
technical field [0001] The invention belongs to the technical field of urban planning. Background technique [0002] The existing urban water resources have the phenomenon of "weird circle", that is, frequent waterlogging and floods in the rainy season, and water shortage in the dry season. The key reason for this is that there is no comprehensive regulation, storage and utilization of rainwater. As one of the most fundamental, direct and economical water resources, the large-scale development and utilization of rainwater has become an important way for many cities in the world to solve the "weird circle" of water resources. In this context, low-impact development technology has been widely used at home and abroad as a new type of rainwater regulation and storage technology, and achieved good results. [0003] LID (Low Impact Development, LID) refers to a rainwater management method based on the principle of simulating natural hydrological conditions and using the concept ...
