Optimization of Green Infrastructure in Xinyang CityBased on Network Structure Analysis

Abstract

Based on the case of Xinyang city, the green infrastructure system is extracted according to the “central control point-connecting channel-site”, and then the ecological corridor is extracted by the landscape resistance analysis and the optimization path is simulated. Finally, the optimum scheme and control measures are put forward through the analysis of network structure to verify. The results show that the optimized α index is increases from 0.11 to 0.37, β index is increases from 1.08 to 1.79, γ index is increases from 0.38 to 0.58; the optimized green infrastructure network has higher complexity and connectivity than before, and it has certain habitat network function, which can basically meet the needs of residents.
