Analysis On Dynamic Changes And Tendency Of Rural Landscape Pattern Based On LUCC And Landscape Index

In recent years,driven by a series of policies plannings and economic factors,Yongfu town has developed into a unique agricultural sightseeing town in fujian province.With the rapid development of characteristic rural construction process,land use and landscape patterns have also undergone complex and profound changes,which makes the study on land use and landscape patterns particularly important.This paper takes the Yongfu Town in Fujian Province as as the research area.Under the technical support of ENVI 5.1,ArcGIS 10.1,Fragstats 4.2 and other relevant analysis softwares,combining with the policy,economy and natural development of Yongfu Town,the land use database of Yongfu Town from 2006 to 2018 was established,which can be used to analyze the time-space conversion process of land use types,and the change characteristics of landscape pattern from class-level and landscape-level,and explore the driving forces and the influencing mechanism behind the changes.On this basis,this paper establishes transformation suitability atlas,draws the CA-Markov model into simulate the change trend,and put forward suggestions and development strategies for Yongfu town according to the national policies.The main conclusions are as follows:1.The dynamic attitude of land use change in Yongfu Town from 2012-2018 is much higher than that from 2006-2012,indicating that since the construction of "beautiful village" in 2012,the development speed of the town is higher than that before the construction,and the project has promoted the construction and development of yongfu town comprehensively.There is a certain degree of transfer among different land use types,the construction land is the main transferee and it's total area increases rapidly,the cultivated land is both the main transferee and the main transferee,the transfer out of woodland is much greater than the transfer in.This is due to that urban expansion occupys farmland,and then compress forestsin order to ensure farmland.This change trend is the inevitable evolution in the development and expansion of agroforestry integrated towns in different regions.2.During the period 2006-2018,the change of rural landscape pattern in Yongfu Town is very significant.On the landscape-level,the patch morphology tends to be simple,the dominant patch shows a reduced state,the spatial structure complexity increases,and the degree of human disturbance increases.Among all land use types,woodland is the dominant dominant patch type,which leads to the low species diversity and evenness in yongfu town and is greatly affected by human disturbance.The aggregation degree of landscape-level and class-level decreased slightly,the shape of plaques tended to be simple and regular,and the complexity decreased.It shows that urbanization makes the distribution of all kinds of plaques increasingly dispersed,showing a trend of fragmentation.3.The main natural driving factor affecting land use and landscape pattern in Yongfu Town is slope,the main accessibility driving factors is road system,and the mian social and economic factors are economic development,enterprise investment,and government development plannings.Among these facotrs,the slope is the main limiting factor,the road system and economic driving factor show the spatial attraction to constructions,and the government development planning is the guiding factor.4.According to the land transfer matrix and suitability atlas,the CA-Markov model is constructed to simulate the change trend of land use and landscape pattern in Yongfu Yown in 2024.The analysis of the change characteristics of land use types and landscape indexs shows that the landscape pattern of Yongfu Town during 2018-2024 will basically maintain the previous change trend befor,with the rapid increase of construction land and the serious decrease of forests.Compared with the previous stage,the dynamic attitude of land change was slightly reduced,but still showed a relatively fast dynamic change,showing a trend of increase in the number of patches,shrinking of dominant patches,simple and regular patch shape area,uniform distribution,increased complexity of spatial structure,increased degree of human interference,and further fragmentation.5.Based on the status quo,industrial characteristics and the simulation results of land use and landscape pattern change in 2024,this paper puts forward some suggestions to promote the scientific development of land use in Yongfu Town:(1)According to the Rural Revitalization Strategy,reasonably carry out village planning so as to enhance the ability of self-development.It includes moderately developing agglomeration and upgrading villages,expanding the development space of suburban integrated villages,focusing on building characteristic protected villages,and orderly relocating,revoking and merging villages.(2)Relying on the unique industries and dominant agricultural products of Yongfu Town,highlighting industrial advantages and resource advantages,developing multi-functional sightseeing zones including special agricultural sightseeing tours,summer vacation and holiday resorts.The organic integration of production,processing,leisure,tourism,consumption and health preservation,and the linkage and integration of the one or two and three industries will lead to a comprehensive economic upgrading.(3)Taking ecological livable and eco-tourism as the focal point,optimizing the living ecological safety barrier system by establishing a scientific and orderly modern agricultural production ecosystem.Promoting ecology with industry and promoting industry with ecology will eventually promote healthy and orderly development of Yongfu Town.
