Research On Boundary Delimitation Of Urban Lake Scenic Spot

With the acceleration of urbanization in the past 30 years,scenic spots in China are faced with many problems,including the occupation of land brought by the construction of surrounding cities and the ecological pressure caused by the increasing of tourism population.These problems gradually reduce the value of scenic landscape and make the boundary constantly changing.Among them,the urban lake-type scenic spot is one of the scenic spots with the most complex biological diversity and the most unstable boundary around the city due to its high ecological sensitivity and great influence from the town.The boundary of scenic spot is the boundary protecting its independence,integrity and authenticity.The scientific demarcation of scenic spot boundary is conducive to improving its identificability,ensuring the sustainable use of scenic areas,and protecting the characteristics of scenic areas interlaced with mountains and rivers and humanities in China.Based on the above questions,this paper explores the method of boundary demarcation of urban lake-type scenic spots and forms the following research results:Based on the outstanding problems of urban lake-type scenic spots,this paper considers the significance of boundary demarcation.This paper summarizes the relevant research results of protected land and boundary at home and abroad,summarizes the main problems of boundary demarcation of urban lake-type scenic spots,and determines the research direction of this paper.The following problems exist in traditional scenic area boundary demarcation methods: Firstly,there is a lack of understanding of the important role of scenic resources in boundary demarcation,so that some scenic value areas are easily omitted.Secondly,the boundary demarcation method of scenic spots has no structured systematic,which is not conducive to the scientific protection and the stability of the boundary.Third,the delineation method is subjective and result in the unconvincing demarcated boundary.This paper follows four principles,which are ensuring the features of landscape sources and the integrity of ecological environment,maintaining the continuity of history,culture and social development,satisfying the relative independence of regional units,helpful to the necessity and feasibility of protection,utilization and management.This paper summarizes the above problems and principles,proposes to construct the boundary demarcation system of urban lake-type scenic spots by multi-factor superposition method,draws scenic spots boundaries scientifically.This paper discusses and determines the influencing factors of scenic area boundary demarcation from four aspects: landscape resources,natural geographical environment,human environment and related boundaries.By means of factor selection--factor superposition analysis--boundary demarcation--test factor verification--boundary determination,index layer factors of each influencing factor are extracted respectively.Then,it is graphically and data-oriented and evaluated by single index in ArcGIS software.Thirdly,AHP method is adopted to give weight to each factor,and multi-factor superposition analysis is carried out to form the evaluation result and delimit the boundary of urban lake-type scenic spot.Fourthly,selects inspection factors to check the scientific nature of this kind of scenic spots boundary.Taking Chao lake scenic spot as an example,this paper analyzes the influencing factors of chao lake scenic spot,such as scenic resources,natural geographical environment,cultural environment and surrounding protected land type.The index of the grade of scenery source,topography,landform,geological disaster,hydrology,traffic,built-up area,environmental landscape and other elements is taken as the factor of the boundary delimitation of Chao lake scenic spot.The boundary of Chao lake scenic spot is delimited by multi-factor superposition analysis to verify the practicability of theoretical research results.The boundary of Chao lake scenic spot is determined after selecting landscape source,administrative boundary,relationship with other protected areas,large-scale engineering,disaster situation,tourism resources,water system and other factors as test factors to verify the demarcated boundary.Through this method,the practicability of theoretical research results is proved by practical cases.In view of the problems in the process of case verification,the theoretical methods are optimized and adjusted,and the deficiencies in the study are reflected,so as to provide reference for other studies on boundary delimitation of lake-type scenic spots in cities.By studying the boundary demarcation of urban lake-type scenic spots,the boundary demarcation system of such scenic spots is constructed to coordinate the relationship between urban development and scenic spot protection.The research of this paper clarifies the management boundary of such scenic spots,increases the stability of the boundary of scenic spots,and provides reference for the boundary demarcation of other ecological functional areas such as scenic spots and protected areas.
