Management and evaluation system of sustainable development planning about green infrastructure

Abstract

Green infrastructure is a network of interconnected natural areas and other open spaces. In the case of extremely limited urban space, how to effectively build an urban green infrastructure network and identify those network elements with critical landscape ecological functions is extremely important. In order to provide new modelling and analysis concepts for the construction and management of urban green infrastructure networks, taking the rapid urbanisation of Q city as an example, the MSPA method was used in conjunction with the landscape connectivity index to select the largest contribution to maintaining landscape connectivity. As the network centre of the green infrastructure network, the habitat patch of the site was used to construct the potential green infrastructure network. In the study, area using the minimum path method and the use of spatial syntax analysis to identify the priority of the green infrastructure network based on the structural optimisation perspective, to make the construction of green infrastructure networks more scientific. The research results can provide a research idea and method for the construction of green infrastructure networks in rapid urbanisation areas, and have certain reference significance for the priority evaluation of green infrastructure network elements.
