With the development of urbanization in our country people’s demand for water space and utilization way more diverse,waters as city important green space landscape carries more social and ecological service function,at the same time the development and expansion of urban area high strength,make urban water landscape space is facing a series of threats and challenges,the landscape pattern optimization become a much-needed research discussion.Under this background,the paper selected Kaifeng city waters landscape space as the research object,as a typical built in accordance with the water in the north of the city,Kaifeng rich water landscape resources,ecological environment is complex,and the waters of the space as the skeleton of urban green space system and the development of the tourism economy,for human settlement environment construction and the city had a greater influence on the future development.Therefore,in view of the current situation of the city,optimizing the water landscape pattern can improve the ecological environment of Kaifeng water landscape,enhance urban security and revive the water culture.This paper studies from two aspects: theory and practice.In theory,combing kaifeng of waters in the historical evolution of the landscape pattern,ecological network analysis about the present situation of water landscape pattern space structure analysis and research,and combined with the type of elements of the landscape pattern,distribution and change trend and the present situation of connection degree summary of Kaifeng waters landscape spatial pattern of the characteristics and problems.In order to solve the problems such as lack of overall planning,space fragmentation and lack of ecological benefit in Kaifeng water area,the optimization strategies and methods are put forward.On the macro level,the water landscape ecological network is constructed based on the GI principle.At the middle level,the stability of the pattern network can be improved by improving the permeability of corridors and patches.At the micro level,the marginal space of water landscape is optimized,and the landscape spatial structure satisfying different functions is proposed to improve the marginal benefit.In practice,based on the above research and the background of water system construction in Kaifeng city,the optimal design scheme of water landscape pattern in Kaifeng city was proposed: a multi-functional and composite "water-green" ecological network was constructed through network superposition.Optimization design of main ecological nodes and corridor space form,building a "wedge" river corridor,the "scatter" landscape space connected to water ecological network main body structure,improve water continuity and connectivity of landscape pattern and function in addition to determine the waters edge buffer width and space structure,and selected a typical space planning and design.Making full use of water landscape resources in Kaifeng city,optimizing water landscape spatial pattern from macro to micro system has certain practical significance to the ecological construction of landscape pattern in the main urban area of Kaifeng city. |
