奉新县耕地经营规模在地形梯度上的分布特征
Distribution characteristics of farmland operation scale at different terrain gradients in Fengxin County
摘要
Abstract
Based on the survey data of rural land contractual management right to register ownership in Fengxin County, and through the terrain niche index and distribution index and applying correlation analysis, regression analysis, GIS spatial analysis method, this paper studies the distribution characteristics of farmland operation scale in different terrain gradients. Results show: 1) the average size of farmland operation scale in Fengxin County, which contains 49891 households, is 6.31 block/household and 0.66 hm2/household. More than 80％ of farmers run at a small-scale; 2) farmland operation scale was significantly affected by terrain factors, and there was a negative correlation between them; 3) for those farmers who have more than 10 plots or the contracted area is above 1 hm2, and their distribution index of arable land reached the maximum level in the grade 1 area of terrain niche index, while the dominant position was quickly replaced by those farmers with small operation scale, as the increasing of terrain niche index; and 4) the contracted land plots of different grades and the contracted area of different grades have their own different dominant distribution intervals. All these conclusions provide important reference for rural land management under the new situation.关键词
