Construction Of Ecological Space System And Optimization Of Urban Space Form Under The Guidance Of “ecological Coupling”

With the rapid advancement of urbanization,urban sprawl and the large-scale construction of urban "gray" infrastructure have led to the fragmentation of natural ecosystems,triggering a series of urban problems,building a system in the wave of urban green transformation and ecological civilization A healthy,organic and dynamic city will be an inevitable demand for sustainable development.In urban development,how to balance ecology and construction and guide the healthy development of cities has become a key issue.This article starts with the concept of "ecological coupling",summarizes the coupling relationship between urban ecological space system and urban form,explores the urban ecological system construction strategy,studies the urban spatial form optimization strategy,clarifies the ecological landscape layout elements,and analyzes how ecological landscape dominates the urban form To guide the urban structure to become more efficient and reasonable.The study expounds the coupling relationship between urban ecological space system and urban form through four aspects: the positional relationship,element coupling,functional coupling and structural coupling of urban ecological space system and urban form.Through the mountainous city Xuancheng,the hilly city Huainan and the plain type The city of Suzhou,relying on the geographic information system platform,realizes the effective integration and spatial analysis of multi-source data to generate urban ecosystem data information,which mainly includes three levels: a networked integrity ecosystem constructed through the identification of ecological elements;through ecological importance The hierarchical ecosystem of sexual evaluation and the multi-objective systematic ecosystem realized after incorporating humanistic recreational factors.Based on the construction of the ecological system,the optimization and promotion of the urban spatial structure and form are explored from three aspects: the control,penetration,and leadership of the ecological construction on the city.In summary,based on the perspective of ecological coupling,the article proposes systematic theories and ideas for the construction of urban ecosystems,and discusses a set of optimization methods for urban forms and structures guided by green development,with a view to future urban green transformation and ecology Sustainable development provides reference significance.
