Land use pattern is one of the most important factors affecting the quality of habitats, which is taken as the research objective in this study. Based on the land use data of Ciyao river basin from 1985 to 2020, transfer matrix analysis, superposition analysis, and zoning statistics were carried out by ArcGIS. The impact of main threat sources (cultivated land, urban land, and rural residential land) on water quality was calculated using the investment model. The habitat changes and the impact of the habitat quality of the basin on the hydrological and water quality were analyzed. The findings demonstrated that the land-type conversion in Ciyao River Basin from 1985 to 2020 is mainly manifested in the conversion from cultivated land to construction land (94.49 km2), and from grassland to cultivated land (21.59 km2) and forest land (27.15 km2). The habitat quality of the Ciyao River Basin decreased gradually from North to South. The medium and high habitat quality areas are mainly concentrated in the headwater area of the river. Due to the change in land type, the habitat quality in the headwater area of the river significantly improved from 2005 to 2020, while the habitat quality in the confluence area of the Wuliang section significantly declined from 1995 to 2015. Due to the improvements of habitat quality in the source area of the river and water conservation capacity, the total amount of water resources and annual runoff depth of Ciyao River significantly increased from 2005 to 2019 without significant changes in precipitation. The water quality of the Ciyao River has improved due to development of environmental pollution control and the improvement of watershed habitat in 2016–2020.

Urban park green areas are part of territorial space planning, shouldering the mission of providing residents with high-quality ecological products and public space. Using a combination of several measurement models such as the BCG (Boston Consulting Group) matrix, ESDA (Exploratory Spatial Data Analysis), MLR (Machine Learning Regression), GWR (Geographically Weighted Regression), and GeoDetector, this paper presents an empirical study on the changes in Urban Park Green Areas (UPGAs) in the Grand Canal of China. By quantitatively measuring the spatio–temporal evolution patterns of UPGAs, this study reveals the driving mechanisms behind them and proposes policy recommendations for planning and management based on performance evaluation. The spatio–temporal evolution of UPGAs and their performance in China’s Grand Canal are characterized by significant spatial heterogeneity and correlation, with diversified development patterns such as HH (High-scale–High-growth), HL (High-scale–Low-growth), LH (Low-scale–High-growth), and LL (Low-scale–Low-growth) emerging. The evolution performance is dominated by positive oversupply and positive equilibrium, where undersupply coexists with oversupply. Therefore, this paper recommends the implementation of a zoning strategy in the future spatial planning of ecological green areas, urban parks, and green infrastructure. It is also recommended to design differentiated construction strategies and management policies for each zoning area, while promoting inter-city mutual cooperation in the joint preparation and implementation of integrated symbiosis planning. Furthermore, the spatio–temporal evolution of the UPGAs in the Grand Canal of China is influenced by many factors with very complex dynamic mechanisms, and there are significant differences in the nature, intensity, spatial effects, and interaction effects between different factors. Therefore, in the future management of ecological green areas, urban parks, and green infrastructure, it is necessary to interconnect policies to enhance their synergies in population, aging, industry and economy, and ecological civilization to maximize the policy performance.

“…Habitat quality and habitat degradation maps were generated using InVEST (3.12.0), a well-established software tool that combines information on land use threats and ecological sensitivity to assess habitat quality and ecosystem service value under different land use scenarios [50]. Its effectiveness has been widely validated worldwide, including in case studies conducted in China [51][52][53][54], Iran [55], Ethiopia [56], Portugal [57] and Nicaragua [58].…”

An Integrated Model for Constructing Urban Ecological Networks and Identifying the Ecological Protection Priority: A Case Study of Wujiang District, Suzhou

et al. 2023

As a result of the rapid urbanisation in China, the ecological system in urban areas has become fragmented, posing a threat to ecological stability. Constructing ecological networks is considered a critical strategy to reconnect habitats, restore ecosystems and improve ecological capacity. This research aims to develop a GIS-based model that can inform urban ecological network construction and identify the priority areas for ecological protection in a given urban context. The methodological prototype considers land use, habitat conditions and human interventions from an integrated perspective and has been tested based on a case study in Wujiang District, Suzhou. The results show that (i) 30 critical ecological patches were identified, including 2 vital, 4 important and 24 general cores; (ii) 69 ecological corridors, including 15 vital, 36 important and 18 general corridors, 59 ecological nodes and 24 barriers were determined. Based on these results, this research identified priority restoration and protected areas that urgently require the restoration of ecological networks according to their importance. This research proposes further recommendations on management strategies for construction and protection guidance at macro and micro levels in accordance with existing territorial and spatial planning of Wujiang. The model developed in this research provides a scientific methodology for planning and optimising ecological networks and can serve as a basis for realising ecological protection.
