Explanation Of The Reason Of Farmland Uncultivated In The Main Stream Of Huangshui River

Cultivated land resources are the basic guarantee of national grain security.However,with the rapid development of national industrialization and urbanization process,the arable land resources are sharply reduced,and most of the rural areas have arable land abandonment.How to take scientific and effective measures to alleviate the problem of farmland abandonment in the current rural areas,and to promote the rational utilization and protection of cultivated land resources has become one of the hot issues of concern in the academic circles.The land use structure along the Huangshui River is complicated,the vertical height difference is significant and the social and economic level is different.Based on the questionnaire survey and field investigation,the quantitative analysis is carried out by using statistics,econometrics and other technical means to study the reasons for the abandoned farmland along the Huangshui River main stream.The main conclusions are as follows:(1)According to the field survey of the sample villages along the Huangshui River,the farmers from high elevation areas to low altitudes have different geographical features,such as farmland management,household income variables,farmers' arable land circulation variables,household characteristics variables and other variables,which can be divided into agricultural and animal husbandry compound and grain crops from high to low.Dominant segment,scarce cultivated land and dominant section of economic crops.(2)The phenomenon of farmland abandonment generally exists along the Huangshui River.However,the arable land abandonment area has a certain regional difference from high to low altitude,the abandoned area of high altitude area is the largest,the low altitude area of the economic crop advantage section is the least,the relatively special is the low altitude of the arable land is not abandoned land.(3)The main reason for the influence of the agro pastoral compound section on the arable land abandonment is the farmland management status of the farmers;the main reason for the influence of the crop dominance section is the family characteristic variables;the main reason for the economic crop dominance is that the farmland abandonment is the main reason for the farmland abandonment;the reasons for the abandonment of the cultivated land in the village are special,and the land flow is the land flow.The policy is not perfect and farmers lack awareness of farmland protection.The abandonment of cultivated land in the whole sample line mainly depends on the management status of farmers' cultivated land,and the second depends on the variables of family farmers' characteristics and household income,and finally depends on the influence of the farmers' arable land circulation variables and the disaster on the crop yield.
