Evaluation Of Intensive Cultivated-land Utilization In Baiquan County

Intensive Cultivated-land Utilization is an important means to tap the potential of Cultivated land utilization and promote the sustainable use of Cultivated land resources,and an important way to optimize the allocation of agricultural resources and promote the stable and healthy development of agriculture.China is a large agricultural country,and the village is the smallest administrative unit in China.Improving the level of intensive use of farmland in the village is an important way to improve the development of agriculture and ru ral areas in China.Intensive use of farmland in the village is a process of continuous optimization in the process of agricultural production in the village,which is not only related to the level of agricultural development in the village,but also related to the socio-economic development and the income level of farmers,and has more impact The demand of future generations for sustainable use of Cultivated land.This paper first combs the concept and connotation of the intensive use of farmland at the vi llage level,constructs the evaluation system of the intensive use of farmland at the village level based on the actual situation of 186 villages in the study area,calculates and analyzes the level of intensive use of farmland and its internal differences in each village,analyzes the correlation between the input-state-output of farmland in each village,and explores the constraints on the level of intensive use of farmland in each village According to the results of the analysis,some suggestions are put forward to optimize the utilization of Cultivated land in Baiquan County.The main research contents and conclusions are as follows:(1)This paper expounds the concept and connotation of Intensive Cultivated-land Utilization at village level.By combing the concept and connotation of intensive use of arable land at home and abroad,combining with the current situation of Cultivated land use in the study area and the level of agricultural development in each village,the concept of intensive use of rural a rable land is summarized,and the essence and connotation of intensive use of rural arable land are explained in combination with relevant theories.(2)The evaluation system of Intensive Cultivated-land Utilization at village level was established.After combing the relevant research,combined with the actual situation of each village in Baiquan County,the representative evaluation indexes of Intensive Cultivated-land Utilization are selected and the evaluation system of Intensive Cultivated-land Utilization at village level based on PSR model is constructed.Entropy method and expert scoring method are used to give comprehensive subjective and objective weights to each index,and then the overall level of Intensive Cultivated-land Utilization and the internal differences of each criterion level in each village are improved According to the level of Intensive Cultivated-land Utilization,input intensity of Cultivated land,output level of Cultivated land and utilization degree of Cultivated land,186 villages were classified by using the natural section point method.Conclusion: the intensive use level,input intensity and output level of Cultivated land in most villages in the southwest,a small number of villages in the southeast,and some villages in the north of Baiquan County are generally on the high side,while those in other areas are generally on the low side;the utilization level of Cultivated land in villages in Baiquan County is spatially irregular,but on the whole,it is high in the southwest plain,other hills and hills The result of low distribution in shallow mountain area.(3)The correlation of input state output is analyzed.After the input intensity score,output level score and utilization degree score of 186 villages are obtained by the comprehensive weighted summation model,the correlation between the input intensity,output level and utilization degree of Cultivated land and the intensive utilization level of Cultivated-land,as well as the input intensity,output level and utilization level of Cultivated land are calculated by the linear regression model The results show that the correlation among output level,intensive level,utilization level,intensive level,input intensity,intensive level,and utilization level,output level,input intensity,output level,input intensity,and utilization level.(4)Dividing the development mode of Intensive Cultivated-land Utilization in every village of Baiquan County.First of all,through the obstacle degree model,the internal obstacle factor s and the obstacle degree that restrict the intensive use level of Cultivated land in each district of Baiquan County are calculated,and the development mode of Intensive Cultivated-land Utilization is divided according to the analysis results of natural conditions,social economy,location conditions and intensive use level of Cultivated land in each district,so as to obtain the centralized scale,comprehensive forerunner,collaborative service Characteristics-mining,renovation-Optimization of five business models,and put forward the future development of agricultural countermeasures and suggestions,to promote the intensive and large-scale development of the Cultivated land in Baiquan County.
