Analysis And Optimization Strategy Of Urban Landscape Problems In The Current Situation Of Qian Shan Town Spatial Pattern

Since China’s urbanization policy has been carried out,the ecological and environmental problems caused by the special regional environment of cities and towns have gradually emerged.The rapid development of urbanization makes it lack of overall planning,unreasonable spatial layout,various types of land use are chaotic,public facilities construction can not keep pace with the pace of human development,farmland protection is not effective,indiscriminate mining and indiscriminate occupation of cultivated land are serious.Since the "ecological planning and ecological construction" was put forward in China,the urban landscape problem has been a comprehensive research for scholars.The best way to ensure the stability of natural ecology is to use the theoretical basis of landscape ecology to solve the problem.In this process,the importance of natural ecology is particularly critical.To achieve this,we need to protect and optimize the living environment of natural animals and plants,and improve the utilization rate of renewable energy.This paper obtains the corresponding landscape elements and the data of various land use types from the raster processing of Arc GIS software,and obtains the basic landscape spatial pattern of Qianshan Town through landscape index analysis.Based on the analysis of landscape spatial pattern,the existing landscape corridor of Qianshan Town is obtained by analyzing the hydrology and traffic of Qianshan Town by geographic cloud data.According to the analysis of land use type,landscape index and landscape corridor,the data model and landscape matrix and network pattern of Qianshan Town were obtained.Through the suitability evaluation of landscape land type,it is concluded that Qianshan Town is suitable for living environment,and then the visual analysis of landscape visual domain is carried out again.On this basis,the urban landscape problems of Qianshan Town are explored.Qianshan Town is a typical agricultural landscape,the forestry landscape type has the greatest superiority,rich biodiversity,no tertiary industry development,this phenomenon is closely related to its geographical location and surrounding environment.The serious fragmentation of woodland landscape edge is also due to excessive human activities.Residents pay less attention to the unused land and water area,and have less impact on the overall landscape of Qianshan Town.The distribution of construction land is more complex,and the surrounding scattered areas show that Qianshan Town is gradually approaching urbanization due to the particularity of its geographical location,and the scope of construction land is increasing.In the visual analysis,the range of view is determined according to the suitability standard,and the dynamic and static line of sight area of Qianshan Town is analyzed.Since the dynamic viewpoint is within the scope of the traffic route,the scope of view is related tothe surrounding environment,such as building facilities,public facilities and greenways,etc.,and the scope of view is mainly road landscape;when the static viewpoint is within the scope of construction land,cultivated land and forest land,the scope of view will be related to the surrounding natural landscape or public facilities,and the viewpoint will change with the elevation Therefore,the scope of vision will also change accordingly,and a wider range of urban landscape can be observed.After visual analysis of Qian Shan town,the urban landscape problems are obtained,and the reasonable optimization suggestions are given to the urban environment of Qian Shan town from the perspective of landscape ecology and landscape aesthetics.Integrate the scattered cultivated land into woodland,combine some construction land with woodland,and improve the greening rate of residential areas;Design and plant shelterbelts on both sides of the water environment to achieve the effect of conserving water and soil;Combined with the landscape characteristics of the road area,place the road infrastructure;Increase residents’ activity space in the town center to meet residents’ daily recreation needs.Establish protection and maintenance measures for the urban landscape of Qian Shan Town and develop the tertiary industry,so that Qian Shan Town can truly realize the livable and professional life of residents under the policy of beautiful countryside.
