Intelligent Monitoring And Driving Force Analy Is Of Land Use Change Based On Remote Sensing Technology

Land is one of the basic elements of national state,it is important material base,is the human survival and development of land is a kind of valuable resources at the same time,with the development of urbanization,a large amount of land occupied,increasingly scarce land resources,how to reasonable and efficient use of land is an important topic of the current research,and the study of land use/cover change,is very good to solve this problem.With the increasing interference of human activities on natural resources,the influencing factors of land use/cover change become stronger and stronger.This paper takes land use/cover change and its driving factors as the research direction to provide scientific basis for the coordinated development of human and land in the future.Yunlong district of xuzhou was chosen as the research area.Firstly,remote sensing image data of the fourth stage in yunlong district is selected and interpreted to obtain the area of land use type of the fourth stage in yunlong district.Secondly,the dynamic attitude of land use and the degree of land use were used to analyze the types of land use in yunlong district from 2008 to 2017.On this basis,the concept of comprehensive index of land use overall change is proposed,and a model is established to obtain the comprehensive index of land use overall change over the years in yunlong district.Then the causes of land use type change are analyzed and studied,and the conclusion is caused by driving factors.Finally,on this basis,the reasonable development and utilization of yunlong district land in the future put forward feasible Suggestions.The research results are as follows:(1)By interpreting the four TM remote sensing images in 2008,2011,2014 and2017,six types of land use including forest land,cultivated land,grassland,water area,unused land and construction land were interpreted.Firstly,the original image is processed technically,including geometric correction,radiometric correction,image clipping and enhancement.Then,it USES supervised classification,unsupervised classification and the combination of the two methods to interpret,classifies the interpretation results,interprets six categories,interprets the accuracy of the specification requirements,not less than 80%,can be used for research and analysis.(2)Through the construction of xuzhou intelligent land monitoring system,land changes in yunlong district can be timely grasped,which is of great significance to land law enforcement,protection of basic farmland,post-grant supervision ofconstruction land,and real-time monitoring of hidden dangers and dangerous points.(3)From 2008 to 2017,the characteristics of land use/coverage change in yunlong district changed significantly.Mainly from two aspects: the number and extent to the analysis,first of all,from the point of quantity change,construction land area has been increasing,at the same time,the cultivated land,grassland,forest land and waters have been occupied area has been reduced,the change of the unused is not regular,early has been falling,began to increase in the middle,finally began to gradually reduce.In each stage of single land use dynamics,construction land grows the fastest,net growth,grassland grows the fastest.It shows a net decrease trend,but the base is small,and the biggest change of decrease is the cultivated land,which decreases year by year.The dynamic of comprehensive land use has been increasing,which indicates that the degree of human disturbance to land use is increasing gradually.Secondly,from the perspective of degree change,the comprehensive land use index shows an upward trend.The change and change rate are both greater than zero and positive,indicating that the land use in yunlong district has been improving and land use is in a stage of rapid development.(4)The comprehensive index model is constructed by using the land use dynamic attitude and land use degree index to analyze the land use situation in yunlong district.The results show that the change trend of the comprehensive index of land use overall change in yunlong district is generally upward.Since 2008,the comprehensive index of land use overall change has been growing continuously and at a faster growth rate,indicating that the comprehensive degree of land use and development has been enhanced and the overall change level of land use has been continuously improved.(5)Analyze the driving factors affecting land use/cover change one by one.The analysis of driving factors mainly includes economic factors,demographic factors,natural factors and policy factors.(6)Through the above research and analysis,combining the land use status of yunlong district,it can provide feasible Suggestions for the development of yunlong district in the future,including industrial structure upgrading,rational control of population resources and basic farmland protection.
