“…The cooling effect of urban blue–green spaces, also known as urban cool islands (UCIs), is an important ecological effect that has attracted increasing attention [ 6 , 7 , 8 , 9 , 10 ]. Waterbodies include rivers, lakes, and reservoirs, while the green spaces consist of trees, shrubs, and grass, which make up the blue–green spaces in urban areas.…”

“…As a special ecological landscape composed of water bodies and green spaces, waterfront green spaces have become important urban areas that provide a liveable ecology and microclimate environment for citizens. A growing number of studies have shown that blue-green spaces can significantly improve urban ecological problems and microclimate effects and increase human comfort perception [1,8,9] The cooling effect of urban blue-green spaces, also known as urban cool islands (UCIs), is an important ecological effect that has attracted increasing attention [6][7][8][9][10]. Waterbodies include rivers, lakes, and reservoirs, while the green spaces consist of trees, shrubs, and grass, which make up the blue-green spaces in urban areas.…”

Different structural patterns of waterfront green space networks in built-up areas have different synergistic cooling characteristics in cities. This study’s aim is to determine what kinds of spatial structures and morphologies of waterfront green spaces offer a good cooling effect, combined with three different typical patterns in Shanghai. A multidimensional spatial influence variable system based on the cooling effect was constructed to describe the spatial structural and morphological factors of the green space network. The ENVI-met 4.3 software, developed by Michael Bruse at Bochum, German, was used to simulate the microclimate distribution data, combined with the boosted regression tree (BRT) model and the correlation analysis method. The results showed that at the network level, the distance from the water body and the connectivity of green space had a stronger cooling correlation. The orientation of green corridors consistent with a summer monsoon had larger cooling effect ranges. In terms of spatial morphology, the vegetation sky view factor (SVF) and Vegetation Surface Albedo (VSAlbedo) had an important correlation with air temperature (T), and the green corridor with a 20–25 m width had the largest marginal effect on cooling. These results will provide useful guidance for urban climate adaptive planning and design.

“…Present as the lateral distance from the centerline of the river to both sides of valley walls, the width of the ecological corridor determines the ecological structure and function of the freshwater ecosystem [ 49 , 50 , 51 ]. As Jiang et al (2016) and Tzolova (1995) suggested, the optimal width of an urban stream corridor and its related functional region ought to be approximately 1000–3000 m, from the perspective of ecosystem structure and function [ 52 , 53 ]. Xiao et al (2020) proposed that most terrestrial species in Jiangsu Province disperse from 3 to 2000 [ 54 ].…”

Along with accelerating urbanization and associated anthropogenic disturbance, the structure and function of freshwater ecosystems worldwide are substantially damaged. To improve ecosystem health, and thus enhance the ecosystem security of the urban ecosystem, numbers of management approaches and engineering projects have been applied to mitigate the degradation of freshwaters. Nevertheless, there is still a lack of comprehensive and systematic research on the ecological corridor restoration of freshwater ecosystems; especially for Suzhou Grand Canal, one section of the world’s longest and ancient Grand Canal which is inclined to severe ecosystem degradation. Through investigating the adjacent land use characteristics, habitat quality, vegetation cover, instream water quality, and habitat composition, we aimed to: (i) assess the water quality of the Suzhou Grand Canal; (ii) evaluate the ecological characteristics of the canal ecosystem; (iii) develop strategic countermeasures to restore the ecological corridors for the mitigation of ecological problems. The results demonstrated: a large built area, a smaller ecological zone, a low habitat quality and habitat connectivity, and a high degree of habitat fragmentation within the canal corridor, also a simplified instream habitat composition, and greater nutrient and COD concentrations in the surface water—especially in the upstream and midstream canal. All urbanization-induced multiple stressors, such as land use changes, altered hydrology, and the simplified riparian zone et al., contributed synergistically to the degradation of the canal ecosystem. To alleviate the ecosystem deterioration, three aspects of recommendations were proposed: water pollution control, watershed ecosystem restoration, and ecological network construction. Basically, building a comprehensive watershed ecological network—on the basis of associated ecosystem restoration, and the connection of multi-dimensional ecological corridors—would dramatically increase the maintenance of aquatic–terrestrial system biodiversity, and improve the regional ecological security pattern and watershed resilience toward stochastic future disturbances. This study contributes to the understanding of the ecological challenges and related causes of the canal ecosystem. The integrated strategy introduced in this study provides policymakers, water resource managers, and planners with comprehensive guidelines to restore and manage the ecological corridor of the canal ecosystem. This can be used as a reference in freshwater ecosystems elsewhere, to improve ecosystem stability for supporting the sustainable development of urban ecosystems.

“…Canto-Perello et al (2016) have developed an A'WOT hybrid method combining SWOT technique and AHP to promote the sustainable use of the urban underground space. Jiang et al (2016) have studied healthy urban streams of the Suzhou creek corridor in Shanghai applying AHP with GIS data analysis and GIS space technology. Kamaruzzaman et al (2016) have confirmed the Delphi method as the most applicable technique to develop comprehensive building environmental assessments.…”

Selecting a river rehabilitation project is a complex decision which should address social, economic and landscape indicators. The rehabilitation project becomes even more complicated if the city qualifies for inscription on the UNESCO World Heritage List. Tangible and intangible factors must be assessed to take into account cultural and natural heritage, water flow, river naturalization, interaction of water stream, construction costs and operational and maintenance costs. The proposed method is a hybrid model combining Delphi, Analytical Hierarchy Process and VIKOR technique. This hybrid model has been applied to the historic walled town of Cuenca and the Huecar river. The objective of the selected rehabilitation project must be the optimal integration of the river in the townscape. The indicators most valued by the panelists have been cultural heritage and river naturalization with 28% and 25% respectively. As a result, the trapezoidal cross section has achieved an acceptable advantage and stability over the modified triangular cross section, valued as second.
