Transformation Of Farmland Use And Driving Mechanism In Xinjiang

As an important factor of agricultural production,farmland is of great significance to realize the strategy of rural revitalization.China has implemented the most stringent arable land protection system,but the form of farmland protection is still severe.As the social and economic transformation enters a new stage,the management of farmland use faces a new situation.The study of farmland use transformation promotes the coordination of farmland use management with socio-economic development.In the past 20 years,Xinjiang has experienced rapid socio-economic development and significant changes in land use patterns.In the new western development period,it is of great practical significance to promote the transformation of farmland use management mode to the direction of socio-economic development for farmland conservation in Xinjiang.Based on the four aspects of "conceptual connotation-phenomenon description-mechanism explanation-optimization and control",the research progress on the transformation of farmland use is sorted out,and the spatial and functional patterns of farmland use are constructed from two levels.The evaluation index system of cropland utilization index was constructed to measure the transformation of cropland utilization.This thesis selects five periods of land use and socio-economic statistics in 2000,2005,2010,2015 and 2018 to study the spatial and temporal evolution characteristics of arable land use transition in Xinjiang since the Western Development,analyzes the driving factors of arable land use transition in Xinjiang using the parametric optimal geographic probe model,and explores its driving mechanism.The main findings of the study are as follows.(1)The transformation of farmland use in Xinjiang towards scale and multifunctionality since the Western Development has basically coincided with the degree of socio-economic development changes.The temporal trend of transformation of farmland use in Xinjiang mainly shows a growth trend,with fluctuating growth type.The spatial transformation of farmland use and functional transformation in most counties(cities)show the same direction of change;in addition,the transformation of farmland use is characterized by spatial agglomeration,and the degree of agglomeration is on the rise,mainly concentrated in the Ili Valley,the economic zone on the northern slope of Tianshan Mountain,and the Kashgar area.The spatial transformation of farmland use in Xinjiang is different from the trend of change in the degree of agglomeration of the functional transformation of farmland use,and the degree of agglomeration of the functional transformation of farmland use increases,but the spatial transformation of farmland use decreases.The center of gravity of both spatial transformation of farmland use and functional transformation of farmland use generally moves to the northeast,and functional transformation of farmland use moves to the southwest by another 18.53 km during 2015-2018.the center of gravity of spatial transformation of farmland use is to the northwest of functional transformation of farmland use.(2)The transformation of farmland use in Xinjiang is influenced by natural and socio-economic factors,and the influence of different factors and their interactions are different in different periods.Distance to water system is the most important natural geographical factor affecting the transformation of farmland use,and its influence is decreasing.The economic level has no direct influence on the transformation of farmland use in Xinjiang and promotes the influence of other factors on the transformation of farmland use.The Chinese government has introduced a series of policies to promote social stability and economic development in Xinjiang in the past 20 years,which directly or indirectly influenced the transformation of farmland use.Western development has greatly contributed to the transformation of farmland use in Xinjiang,mainly promoting spatial transformation.(3)The transformation of farmland use can be optimally regulated by three paths: land engineering,land management and socio-economic development policies.Taking into account the natural background conditions and socio-economic situation in Xinjiang,a total of 4 suggestions for optimal regulation are proposed from 3 paths: land engineering,land management and socio-economic development policies to promote the construction of high-standard farmland,strict thresholds for the development of farmland reserve resources,promote land transfer,and accelerate the construction of rural tourism.The above 3 paths are further prioritized according to the transformation characteristics of farmland use in 85 county-level research units.There are 64,3,7,and 11 county-level study units in the functional transformation priority area,spatial transformation priority area,functional transformation incentive area,and spatial transformation incentive area,respectively.The results can provide decision aid for the management of farmland use in Xinjiang during the new western development period,and provide a decision basis for achieving the goals of sustainable farmland use and agricultural and rural modernization.
