“…The flow direction map is always computed based on elevation map. Noticeably, as stressed by Arbault et al (2014), the accumulation function in ArcGIS calculates values upstream of a grid cell, i.e. the amount inflowing to the cell.…”

“…Hence, spatial differentiation in water flows characterization is essential to improve the quality of EME results. Arbault et al (2014) Therefore, it is highly recommended for the emergy community to foster the use and improvement of such high-resolution, spatially explicit dataset instead of using biota, because of higher stream productivity and associated higher quality of dietary sources, at least in the short-term. Ghadimi (2014) The results confirm that effective dam operation could contribute to a decrease in pollutant loads in the receiving seawater body.…”

“…Until now, the emergy-GIS method mainly focused on family farm analysis [41], resource monitoring applications [42], evaluation of renewable resources [43], sustainability studies of rivers [44], land use analysis [45], landscape classification [46], product productivity analysis [47], sponge city design [48], and ecosystem structure [49]. The current research lacks studies and analysis on urban sustainability, and this article precisely fills this gap.…”

Sustainability studies are vital for the long-term development of ecological cities. For cities, single qualitative or quantitative evaluation studies cannot effectively illustrate the ecological and sustainable status of a city. This study employs the emergy–geographic information system (GIS) method to conduct a sustainability evaluation of a city, so as to effectively verify the evaluation results. The emergy method and GIS are both commonly used approaches to address urban issues, but their synergistic effect has rarely been considered, explored, and utilized in urban planning. This study aims to investigate this effect on Hangzhou city through comparative analysis. The results show that rain (geopotential energy) and rain (chemical potential energy) have the highest emergy values from 2000 to 2035, followed by solar emergy, wind emergy, and geothermal heat emergy. These findings are also supported by the GIS map that shows a similar pattern with renewable emergy. Using the five plots (cropland, woodland, grassland, water area, and built-up land) on the GIS map as examples, the accuracy of emergy calculation results for Hangzhou city can be verified, demonstrating the effectiveness of the emergy–GIS methodology. This research provides practical recommendations for city designers and professionals worldwide on urban sustainability. By incorporating both emergy and GIS methods, cities can make informed decisions toward achieving environmentally sustainable development.
