Evaluation And Optimization Of Urban Green Space Network Under The Guidance Of Human-bird Harmony

Harmony is an eternal topic that has been discussed in China and the West since ancient times.However,with the expansion of urban land and destruction of ecological environment worldwide,the balance between human and nature has been broken,especially the encroachment of a large number of forests and grasslands,resulting in the living space of wild animals being continuously compressed,with some going extinct and some being forced into the city,and the contradiction between human and wild animals coexisting has become more and more prominent.In this context,it is of great theoretical and practical significance to select the most widely distributed,common and ecologically important birds as urban wildlife indicator species,and to use urban green space as a bearing space to build an urban green space network that meets human and bird needs,coordinates human and bird coexistence,and promotes the harmony between human,bird and human and nature.Human-bird harmony is a higher level of coexistence based on the satisfaction of basic needs,which is appropriate,stable and orderly.This paper takes the harmony between humans and birds as the guide,and innovatively evaluates and optimizes the urban green space network from the dual perspectives of urban residents and urban birds,considering both the ecological function of the green space network as an important habitat for urban birds and its social function as a major leisure space for urban residents,and at the same time resolving the spatial conflicts between humans and birds in the urban green space network to build a highly accessible,highly connected,high-quality urban green space network that is conducive to The network of urban green space is highly accessible,highly connected,high quality and conducive to the harmonious coexistence of humans and birds.Based on the results of the analysis,the green space network in the study area has insufficient quantity,unbalanced spatial distribution,and more blind areas of park green space services,etc.The MSPA green space landscape pattern analysis,green space landscape connectivity analysis,and MCR model bird flight dispersion resistance analysis are used to evaluate the green space network based on the perspective of urban residents.Based on the results of the analysis,the green space network in the study area has problems such as heavy obstruction surface running from east to west,encircling ecological source patches and poor connectivity between ecological source patches;based on the results of the evaluation and analysis,the green space network is optimized,and the service level and spatial layout of existing parks are optimized to improve park green space services and meet the demand of urban residents for park green space recreation services.By protecting core patches and important ecological corridors and adding stepping stones to improve the green space network,urban birds’ demand for habitat quality and connectivity is met.The plan will be graded and zoned to resolve human-bird conflicts and promote human-bird harmony.
