Research On Control Zoning Method Of Villages At The Northern Foot Of Qinling Mountains

As an important water conservation area in China,the northern foothill of Qinling mountains is the transitional zone of mountain and plain.Because of the lack of effective measures for the management of land resources,in recent years,dominated by the economic interests of the tourism development projects and real estate projects,development of ecological agriculture in the north Qinling escalating,resulting in a series of environmental problems,main show is the deterioration of environment,the decrease of biodiversity,and soil erosion,etc.Based on the need of ecological protection in the northern foothills of Qinling mountains,this paper puts forward the concept of village control zoning in the northern foothills of Qinling mountains,and puts forward the requirements of village control zoning in the context of rural revitalization,beautiful countryside and territorial space planning.At home and abroad are given for the village controls partitions without a systematic research method,this paper select Qinling effect in the three most common administrative villages as the research object,try to RS and GIS technology as the main research method,combined with the third classification system and Sansheng land,two methods of village control zoning,induction method and comprehensive evaluation method.First is a good land of induction,the method using land for junior class around the direct access controls in the study area partition,given the growth of population and economic development,adopt the trend prediction method,time series method and quota method to modify land for production and living,on this basis to get the final result control partition;The second is the comprehensive evaluation method,which believes that the delineation of control zones should be a process of natural and human factors acting together,and that appropriate evaluation factors should be selected to establish a reasonable evaluation system,so as to evaluate the ecological importance of the research areas and partition the research areas according to their different importance.Through the experimental analysis,it is found that the two methods can reflect the rationality of the results of control zoning from different angles.
