Abstract
The delineation of urban development boundaries (UDBs) is an essential part of spatial planning and a powerful tool for implementing spatial governance. With the central city of Nanjing as an example, we used various models, including the logistic regression analysis model, InVEST model, and cellular automaton (CA) model, to evaluate the ecological importance, simulate the spatial expansion of construction land, and delineate the UDBs of various urban spatial units under ecological constraints, and determine the eco-environmental effects of the obtained UDBs. The results revealed that the important ecological lands, which were mostly woodlands, covered 422.05 km2 and acted as the ecological bottom line for regional sustainable development. The simulated UDBs under ecological constraints considered the dual demands of urban spatial expansion and a high-quality eco-environment; they effectively prevented urban expansion from occupying important ecological lands and destroying regional eco-environmental quality. The obtained UDBs were highly consistent with the proposed urban layout of local governments, and our simulated results of the UDBs could provide differentiated development orientations from the perspective of land use protection and development. Finally, we noted that urban expansion is dynamic, complex, and systematic and is also affected by the interaction of multiple factors, and the constraint of ecological importance should be emphasized to coordinate the relationship between land development and ecological protection.
期刊介绍:
The ultimate aim of Ecological Indicators is to integrate the monitoring and assessment of ecological and environmental indicators with management practices. The journal provides a forum for the discussion of the applied scientific development and review of traditional indicator approaches as well as for theoretical, modelling and quantitative applications such as index development. Research into the following areas will be published.
• All aspects of ecological and environmental indicators and indices.
• New indicators, and new approaches and methods for indicator development, testing and use.
• Development and modelling of indices, e.g. application of indicator suites across multiple scales and resources.
• Analysis and research of resource, system- and scale-specific indicators.
• Methods for integration of social and other valuation metrics for the production of scientifically rigorous and politically-relevant assessments using indicator-based monitoring and assessment programs.
• How research indicators can be transformed into direct application for management purposes.
• Broader assessment objectives and methods, e.g. biodiversity, biological integrity, and sustainability, through the use of indicators.
• Resource-specific indicators such as landscape, agroecosystems, forests, wetlands, etc.
