Optimization Of Ecological Spatial Pattern In Yuanyang County Based On Conflict Reconciliation

In the process of urbanization,the contradiction between urban ecological environmental protection and urban expansion has gradually become obvious,and the quality of urban ecological space has declined,the area has shrunk,the function has been destroyed,and the problem of spatial conflict has emerged frequently.In this context,this paper aims to protect ecological space,rationalize urban and agricultural space,and alleviate spatial conflicts,and takes the ecological space of Yuan Yang County,a typical plain agricultural city in the Yellow River Basin,as the research object,with the goal of optimizing ecological spatial pattern.Based on the ecological background conditions of the county,we evaluate the spatial suitability of the ecological-agricultural-urban areas of the county with reference to the spatial development suitability assessment of the country,and designate ecological protection,food Secondly,the spatial conflict areas in Yuanyang County were precisely identified by applying the method of landscape pattern conflict and the comparison method of suitability evaluation and current land use,analyzing the causes and characteristics of the conflict patches,and formulating conflict and reconciliation strategies by combining the advantageous functions of the patches;finally,the ecological background conditions of Yuanyang County were investigated,ecological source sites were selected,and the potential ecological corridors were extracted by using the minimum resistance model(MCR).Finally,by investigating the ecological background conditions of Yuanyang County,selecting ecological source sites,extracting potential ecological corridors using the minimum resistance model(MCR),selecting ecological corridors to be upgraded by combining new green space patches,and optimizing spatially conflicting patches and corridors to be upgraded by using landscape coordination strategies,a new ecological spatial pattern of Yuanyang County is constructed.The main research findings are as follows:(1)Evaluate the suitability of three types of territorial space development,and comprehensively delineate the regional advantageous functional areas: the ecological protection advantageous area in Yuanyang County accounts for 26.0% of the overall space;the urban construction advantageous area accounts for 28.7% of the overall space;the food production advantageous area accounts for the highest proportion,45.3% of the overall space.The ecological protection advantageous areas in the county are mainly located along the Yellow River and Qijie town,which need to be strictly protected;the urban construction advantageous areas are mainly located in the county city and the plain demonstration area;the agricultural production spatial advantageous areas are widely distributed in the non-urban areas of the county,among which Taiping town and Guozhuang are the high quality areas for agricultural production.(2)Diagnosis of spatial conflicts and identification and analysis of conflict patches: from the landscape pattern conflicts,the overall spatial conflict index of the county shows an increasing trend between 2000 and 2020,and the serious conflict units are mainly gathered in the central city of the county and the western plain demonstration area,which indicates the disorderly expansion of the town and the urgent need to take measures to restrain its disorderly development;among the identified conflict patches,the ecological-agricultural spatial conflict Among the identified conflict patches,the most ecological-agricultural spatial conflict patches are located in the eastern part of the county and along the Yellow River in the southeastern part of the county,these patches are in the high ecological suitability area,but the agricultural sprawl is crowding the ecological suitability area;followed by urban spatial conflict patches,mainly located in the western and northwestern part of the county,these areas are the dominant areas for urban development,and the direction of urban development lacks the guidance of dominant functions;ecologicaltown spatial conflict patches are mainly located in the In addition,ecological-town spatial conflict is also found in the southeastern part of the Yellow River,where there is a rural living group adjacent to the Yellow River,and this area has strong sensitivity to soil erosion and is an ecological protection zone.This area is very sensitive to soil erosion and is a very important area for ecological protection,so it is not suitable for village life.Only a small part of the rural living space in the farmland-town spatial conflict area is located in the highly suitable area for farmland,and measures such as village relocation and annexation can be taken.(3)Analysis of the current ecological pattern and selection of ecological corridors to be upgraded: Using the minimum resistance model to derive potential ecological corridors in Yuanyang County,it is found that there are many ecological source sites within the Yellow River beach area,with little ecological resistance,which is conducive to the formation of a stable corridor network and superior conditions for the construction of ecological corridors;the construction land in the central county of Yuanyang County is dense,lacking ecological source sites,with high resistance to the construction of ecological corridors;the spatial density of the eastern town is small,with a wide agricultural space and little ecological resistance.The eastern town has a small spatial density,a wide agricultural space,a small ecological resistance,but a lack of ecological sources,and no corridors passing through the east,so the focus should be on building ecological corridors and stepping stones in the central county and the east.This study completes the cross-scale macro planning and control to micro restoration design: at the macro level,based on the spatial conflict patches and the analysis of the existing ecological background conditions in Yuanyang County,new green space patches and corridors to be upgraded are designated,and a new ecological network pattern of "two horizontal,four vertical,and multiple branches" is constructed;at the micro level,typical conflict patches and ecological corridors to be upgraded are selected.At the micro level,typical conflict patches and ecological corridors to be upgraded are selected,rigid planning and flexible design are used to coordinate spatial conflicts,and landscape design strategies are applied to optimize the design of conflict patches and corridors to be upgraded.
