Study On Spatiotemporal Evolution Characteristics Of Cemetery Land Spatial Pattern In Tonglu County

Cemetery as a measure of a city civilization and progress of the standard,its scientific and reasonable layout for the city landscape and environment is of great significance.However,there are still many problems in the spatial layout of cemeteries in China.Therefore,the paper studies the spatio-temporal evolution characteristics and driving factors of the spatial pattern of cemeteries,draws the conclusion that the shortcomings exist in the development process of cemeteries,and puts forward relevant optimization suggestions,which has certain significance for guiding the construction of cemeteries in the future.Cemetery in tonglu county as the research object,is firstly established through field investigation and combining Arc GIS vector database,then use mathematical statistics and analysis method of Arc GIS spatial temporal and spatial distribution of land use spatial pattern study cemetery evolution characteristics,analyzed the evolution of relevant again drive factors,and finally summarizes the deficiency in tonglu county cemetery development and put forward the corresponding optimization strategy.The main research results of this paper are as follows:(1)From 2004 to 2019,the number and scale of cemeteries in Tonglu County have been increasing and the growth rate has been accelerating.On the whole,from 2004 to 2019,tonglu County cemetery has been in a state of aggregation,with the largest concentration in 2014..The highly concentrated area extends from the central urban area to the surrounding towns(streets),and then to the secondary central towns,finally forming a cemetery land space structure with the central urban circle and secondary towns as high-density distribution hotspots,and general administrative towns as low-density distribution hotspots around the distribution.The dominant direction of spatial distribution is always "southeast to northwest",and the significance of the direction first weakens and then strengthens,and the direction is most obvious in 2019.(2)Spatial and temporal evolution of cemetery land pattern in Tonglu County is influenced by natural factors,population factors,traffic factors and policy factors.Natural factors are the foundation of the spatial pattern of cemetery plots.Population factor is the demand base of cemetery construction to meet the expanding population scale and the increasing aging phenomenon;Traffic factors affect the spatial distribution of cemeteries.Policy factors regulate the construction of cemeteries,including the construction scope,number and scale of cemeteries.(3)Spatial layout of cemeteries in Tonglu County has some problems,such as unreasonable site selection,unlimited expansion of cemeteries,and inability to keep pace with policies in cemetery construction,which have caused serious impacts on urban landscape and ecological environment.Based on these problems,corresponding suggestions for optimization and reconstruction are put forward.
