Charateristics And Driving Forces Of Spatio-temporal Of Cultivated Land Use Change In Qianjiang

Land is the foundation of human survival, while arable land is the key and most important type of land use types, the material basis of human food production, the most important means of production in agricultural production, and also to ensure people’s food problem and national food the basic protection of the security. China’s arable land resource issues show less per capita arable land, The quality of arable land is not high, and arable land reserve resources is less.With the continued development of the socio-economic, arable land resources will continue to reduce, and the contradictions of the people and land is still sharp.So In this context, do the reasaerch of farmland utilization changes and driving forces of Qianjiang City is significant,and itcan provide references for the protection of the farmland.This article is based on land use of the Qianjiang City, and combined with the data of the first National Land Use Survey and the second National Land Survey, and the data of socio-economic statistical, using the MapGIS software and SPSS statistical analysis software to analyze the amount of cultivated landchanges in the spatial variation in Qianjiang City; Use the method of principal component analysis and multiple linear regression model for comparative analysis of the driving force of the amount of cultivated land change, and to study the analysis of factors affecting arable land change; On this basis, against The problems for the cultivated land use change, proposed farmland protection countermeasures in several aspects. The article is divided into six chapters:(1) Introduction.This part researches the background and significance of this article, domestic and international progress in LUCC research, Content and methods of the study.(2) Theory. This section describes the concept of LUCC, content and research methods.(3) The overview of the study region. This section includes the natural conditions, socio-economic development, traffic conditions and the land-use status of Qianjiang City.(4) Analysis of the arable land use change. This section is draws on existing research, and use oits methods,to analyze the magnitude of cultivated land use change, the speed of arable land change, changes in farmland structure, spatial variation of the arable land, extent of cultivated land use change and the change of arable land reclamation rate. Do a in-depth study in the characteristics of City Land use change in Qianjiang.(5) Analysis of the driving forces of farmland change. This section is based on the research of the third chapter.This part does the reasearches about qualitative analysis and quantitative analysis for the driving forces of farmland change. And described the reasons, strength and mechanism.(6) Measures of farmland protection. This section presents the feasible measures for the conservation and sustainable use of farmland in Qianjiang City.(7) Conclusions and prospects.This part discusseed the research results of the article, summed up the shortcomings, and provide ideas for future further research.
