Abstract

The acceleration of urbanisation has led to the aggravation of the problem of fragmentation of urban ecological space, and the construction and optimisation of ecological networks play an important role in alleviating urban ecological problems. Based on the problems of ecological fragmentation and lack of wetlands and greenery in Changchun City, this paper constructs an ecological corridor network in Changchun City through the methods of Morphological Spatial Pattern Analysis (MSPA), Minimum Accumulation Model (MCR) and Circuit Theory, conducts a quantitative analysis of ecosystem services and ecological restoration of the central urban area from the whole network to the macro to micro level, and proposes the optimisation strategy of ecological network. The study shows that: (1) the optimisation of the ecological network from the whole to the region is more objective; (2) the Changchun ecological network consists of 40 ecological sources and 82 potential ecological corridors; (3) In various development scenarios, incorporating the peripheral ecological source areas from the edge of Changchun’s central urban district into the spatial layout of the city center yields the greatest ecological improvement for the urban.
