摘要
A comprehensive framework composed of stormwater indices (e.g., stormwater runoff, runoff pollution) and anthropogenic heat is proposed to facilitate selection of key areas for sponge-like urban reconstruction based on the integration of emergy analysis and GIS models. A case study in Shenzhen is used to evaluate the effectiveness of the proposed methodology in aiding the implementation of sponge city reconstruction. Specifically, natural and man-made releases are identified and accounted for in emergy units (seJ). When compared to the emergy values of natural releases (4.99E + 14-7.59E +14 seJ) and man-made releases (1.79E + 14-5.8E +16 seJ) within the Shenzhen Basic Ecological Control Line (designated as an ecological preservation area), the emergy values of both types of releases outside the Basic Ecological Control Line are higher, ranging from 7.59E+ 14 seJ to 8.32E +14 seJ for the former and from 5.8E +16 seJ to 1.86E + 17 seJ for the latter. Nine sub-districts in Shenzhen, China, such as industrial parks, transportation and bare land for construction are preliminarily chosen as areas for potential sponge-like urban reconstruction on the basis of man-made releases, and are then confirmed by examining natural releases. The proposed emergy-GIS framework can bridge the gap between empirical studies and standardize research to ensure that the results of the green infrastructure plan live up to the rhetoric.
