Beijing City Riparian Zone Land Use Landscape Pattern Analysis And Optimization Of Suggestions

Land use landscape of urban riparian zone is an important part of urban landscape,affects the city development and human’s survival conditions.As to speed up the process of industrialization,the urban land resources shortage of riparian zone by excessive exploitation and utilization,and directly lead to irreversible changes in the riparian zone landscape structure,have a huge impact on the riparian zone ecosystem,urban landscape pattern was unprecedented destruction.Therefore,research the zone landscape pattern and the optimized scheme,for the rational utilization of riparian zone resources and provides some references for the implementation of urban ecological sustainable development.Based on the theory of geography,landscape ecology,and the earth system and other related theory,combined with the latest remote sensing images and field survey data,such as 10 times according to the wide river division of Beijing city riparian zone,and with reference to the Beijing municipal planning bureau issued 2017 "Beijing urban and rural planning and land use land classification of corresponding guide will riparian zone was divided into 10 types of landscape.Using Fragstats4.2 landscape index analysis software,select the appropriate landscape index,using the moving window method,analysis of riparian zone in patches,type,and the spatial structure of landscape level.Finally,based on the ecosystem service value,minimum cumulative resistance model is set up,according to current situation of the zone land use landscape pattern optimization strategy is put forward.According to the research content of this article,the following main conclusions:(1)In combination with the practical situation of the city,analysis of riparian zone in topography and hydrological,ecological protection and visual landscape conditions should have the research scope.The terrain lines to hydrological,ecological protection and visual landscape line graphic overlay,get lines to topography and hydrology is the largest scope,can contain involved topography and hydrology,riparian zone of ecological protection and visual landscape information,therefore,according to the topography and hydrology line 10 times both wide river divides urban riparian zone.On this basis,by reference to Beijing’s urban and rural planning and land use land classification the riparian zone into corresponding guide: land for public administration and public services,Shang Fu land and transportation land,residential land,green land,cultivated land,forest land,garden land,water and other land for the 10 kinds of land use types.(2)Urban riparian zone land use spatial characteristics of landscape pattern is:residential land are the main landscape types riparian zone landscape.Green land,forest land,cultivated land,garden land shall be carried out in accordance with the ecological land area statistics,less than the percentage of the residential land area of landscape area,that central Banks with affected by human activities,the fragile ecological environment.Transportation land patch number is much higher than other kinds of means transportation land fragmentation is the highest.Residential land area and the largest number of patches is not the most,that there is a larger area of residence land of plaque,the number of patches from land transportation compared with the number of residential land,residential land it plaque shall appear,mostly in a landslide affects the composition of landscape.(3)In order to better play to the landscape function,promoting regional connectivity,urban riparian zone landscape pattern optimization of land use from the ecological source,ecological corridor,and the perspective of three different ecological node,specific include:one is to strengthen the protection of the ecological source,such as increase the forest land and waters landscape area,ensure the riparian zone around a certain width of buffer,strengthen the construction of protected areas such as forests,rivers,and ecological park,giving full play to the advantages of riparian zone environment,create the opening space landscape is unique;Second,increase the construction of the ecological corridor,increase the accessibility of rivers,strengthen the interaction between citizens and the rivers,try to avoid "road clip river" wait for a phenomenon,the river construction hydrophilic trails,waterfront buildings,Bridges,parks,zero distance close to the river,so people can enjoy the pleasure of rivers.According to the features of at the same time,the river can be divided into different themes such as ecological sight and human sight;Three is to strengthen the control of ecological node,such as increasing construction of the urban leisure square and the park green space,green space area the ecological nodes are added,forming a three-dimensional green space system of the city.
