| The complex and diverse topography of mountain cities breeds rich landscape patterns.As an important part of the natural habitat space of river system in mountain cities,the riverside zone in the edge area has become an important space carrier of natural society,urban and rural areas,water and land environment,and a key link of ecological environment protection,green industry development,urban and rural construction.It has great practical significance for the construction of beautiful China and poetic human settlements.However,the complex and fragmentary characteristics of the riparian zone in the mountainous urban fringe are more and more obvious due to the multiple interwoven influences of natural society,protection and development,which has restricted the healthy and healthy evolution of the riparian zone and the output of ecological service functions.In the new era of ecological civilization construction and land spatial planning,how to realize the strictest protection and the most efficient use of associated land for riparian spatial ecological elements,give full play to the edge effect of urban and rural areas,improve the defense ability of ecological integrity,and at the same time dig deep-seated environmental value-added,green economy and social service benefits are the values of urban and rural ecological planning An important part to pay attention to.In this paper,the riparian zone of mountain city is selected as the main research object,its land use cover space composition is an important carrier,the natural internal health evolution of riparian ecosystem is taken as the bottom line guarantee,the external urban and rural social demands are met as the goal,the key elements of "landscape,forest,land,lake and grass" are locked,the four ecological service functions of"supporting and regulating the supply culture" are detailed,and the "protection,restoration The four aspects of utilization and management and control are integrated into the whole process of the spatial planning of the riparian zone in the edge area of mountainous cities.Through literature research and field investigation,combined with reference cases and engineering projects,such as Yongchuan District Central City slow traffic system planning,Wanzhou District Urban double repair master plan,the related practical content of the riverside zone in the marginal area,the planning methods of multi-functional comprehensive evaluation,multi River differential construction and global factor use control are summarized: 1 Based on the survey and data analysis,the landscape pattern and compound ecological process of the edge of mountain city are defined.The spatial characteristics of the T3 marginal zone are identified,and the current situation of protection and construction is analyzed.The 2.major functions of the millennium ecosystem are to adjust the supply of literature,support four functions,refine the two level functions and potential indicators,and construct the natural city complex.State service function evaluation system,to determine the ecological service function structure zoning;3.To build multi-scale multi-level landscape network optimization and land use layout mode,to form the riverside spatial planning system with health as the bottom line and external service as the goal;4.To implement the new requirements of land spatial planning,through the use control mode of regional river reach differentiation--link the detailed planning and special planning The new mode of sustainable ecosystem services and public participation organization is put forward.Chapter distribution and content are as follows:(1)The first chapter: the introduction part,to determine the research object,research scope and research focus,combined with the background of the times and practical problems,to comb and build the research methods and framework system,clear the purpose and significance of the research.(2)The second chapter: basic cognition part,in-depth analysis of the practical problems of the riverbank in the edge area of mountain cities,from two aspects of external image performance and internal causes of the problem.The basic theory research,applied theory research and technical method research are carried out for the practical problems as the theoretical cognition.(3)The third chapter: evaluation support part-one of the core chapters,combined with the case support of Yongchuan District(supported by Wanzhou)project,identify the landscape pattern of the edge area and the natural and social complex ecological process.This paper summarizes the characteristics of mountain city construction and river system,distinguishes the characteristics,development status and planning demands of riparian zone,determines the cascade relationship between the natural ecosystem of riparian zone in the marginal zone and the needs of human society,further selects the matching ecosystem service value evaluation method and space mapping method,and clarifies the current situation and ecological cognition.(4)Chapter IV: ecosystem service value evaluation part-one of the core chapters,refine the four ecological service functions of Ma,use "equivalent factor method" to evaluate the natural ecological service function,use "ecological service function matrix" to evaluate the urban ecological service function,and determine the comprehensive ecological service function evaluation and evaluation of riparian zone integrating natural ecological protection and urban social demands through coupling and superposition Spatial distribution.According to the spatial distribution of ecosystem service evaluation and the relationship between supply and demand,the functional structure partition(ecosystem service flow)of ecosystem service is defined.(5)Chapter 5: ecological restoration and spatial planning part-one of the core chapters.Based on the evaluation of ecological service function,the linkage and matching relationship between the evaluation and planning is established.Through the overall protection and system restoration of high-value resources and vulnerable sensitive elements,the pollution prevention and control and disaster interference are focused,and the five methods of "protection,prevention and construction" spatial layout are further integrated.In the composite ecological division At the bottom of the area,the optimization strategy and spatial layout mode are proposed for the land use of the riparian zone to further realize the green infrastructure layout support and the differential site design and section sketch of the upper,middle and lower reaches of the edge area.(6)Chapter 6: use control and Management Optimization: combined with the dual evaluation content of land and space planning,construct the whole area and all factor space control system of riverside zone in mountainous urban fringe.From the meso level of structural zoning,land use and cover control,composite function construction guidance,and micro level of key ecological node construction and riparian ecological control guidance,targeted landing control is carried out.On the basis of strict control,the ecological restoration strategy and method technology guidance of natural work and artificial assistance were carried out.Combined with the new background of land and space planning,the paper puts forward the matching mode and content of planning connection,countermeasures of sustainable management of ecosystem services,multi sector coordination and public participation mode,etc.(7)Chapter 7: conclusion part: review and summarize the ecological service evaluation and planning response method system of riparian zone in the edge area of mountain city,and sort out the innovation and shortcomings of the article. |
