| Intensive use of cultivated land is based on the rational allocation of Level,a land use mode that realizes the sustainable use of cultivated land and social and economic development.This study obtained the spatial distribution difference law and time dynamic change by analyzing the spatial difference level analysis and time series change of cultivated land in Kashi City.The law will help to improve the intensive level of cultivated land in Kashgar,strictly protect basic farmland and cultivated land resources,ensure the food security of the city,and fundamentally analyze the status of cultivated land use and the level of cultivated land utilization,and provide for the development of Kashgar in the next few years.A reliable basis.This paper selects Kashgar City as the research area,the cultivated land area in Kashi City as the research object,analyzes the related theories and related research of cultivated land intensive use,analyzes the land use type and cultivated land distribution of Kashgar City,and masters the land use of the study area.The current situation,combined with the previous research on the intensive use of cultivated land at home and abroad,starting from the development of Kashgar City,combined with the theory of human-land coordination relationship,establishes various evaluation index systems suitable for Kashgar cultivated land use,including pressure indicators,response values and The status indicator is used to evaluate the intensive conservation and utilization degree of cultivated land in the study area,and the comprehensive model is used to analyze the change law of cultivated land use level between 2000 and 2016,evaluate the intensive use degree of cultivated land,and then obtain the results and actual resources according to the analysis.The situation evaluates the intensive use and utilization of cultivated land in each township of Kashi City,and gives corresponding decisions to increase the intensive use of cultivated land and provide the difference in the degree of cultivated land use.The analysis results show that:(1)Constructing cultivated land intensively and using the PSR evaluation model,starting from the contradiction between human andland coordination,studying the connotation of intensive use evaluation of cultivated land,the intensive use of cultivated land refers to the scientific area through limited cultivated land area.Utilize and optimize the structure of industrial layout,increase the input of agricultural production,maximize the economic benefits of arable land use,increase the potential of arable land use,and save valuable resources of arable land,which cannot be wasted because it is natural Non-renewable resources,in terms of the use of cultivated land,follow the principle of sustainable development,establish an indicator system for the PSR evaluation model,and analyze the significance of each factor that has an impact.(2)Evaluation of intensive use of cultivated land in Kashi City.Under the system of PSR evaluation model,the analytic hierarchy process and principal component analysis method are selected to calculate the weight of each index,and the indicators are standardized.The comprehensive evaluation model can be used to obtain the intensive utilization degree of cultivated land in each township.And from 17 years to compare the law of temporal and spatial changes and analysis of the level of intensive use of cultivated land.It can be seen from the calculation results that the intensive use and level of cultivated land in Kashi City is at a relatively low level,and the calculated intensive degree of each township is between 18 and 60.From the space point of view,from 2000 to 2016,the intensive use of cultivated land in Kashi City The level is also at a relatively low level,and several towns and towns around the city center have been in a state of relatively low level of intensiveness.(3)With the help of GIS spatial analysis method,the spatial variation law of the intensive utilization level of cultivated land in Kashi City was analyzed and studied in detail,and the order and practical significance of spatial distribution were explored.From the analysis results,it is clear that there are close correlations between various towns and villages in Kashgar.These related relationships will affect and develop each other,promote the social and economic development of other towns and villages,and strengthen the cooperation of various towns and towns in the future,and guide farmers to carry out modern agriculture.Technical farming,scientific use of cultivated land,thereby increasing the level of intensive use of cultivated land.(4)According to the temporal and spatial variation law and spatial variation law of intensive use of cultivated land in Kashi City,from the perspective of saving the efficiency of cultivated land use,the dynamic balance of ensuring the quality of cultivated land and the change of cultivated land is taken as the starting point,relying on the progress of modern science and technology,thereby improving the cultivated land.Intensive use.Specifically,we can start from the following aspects: establish a farmland protection system;improve the basic farmland protection system;fully promote rural land consolidation,land reclamation efforts to increase the area of ??cultivated land in the study area;eliminate construction land occupation of illegal land;increase cultivated land Comprehensive benefits of utilization;... |
