在奉新县农村土地承包经营权确权调查资料基础上,利用数理统计法和GIS空间分析法,引入地形位指数和分布指数,对奉新县农户的耕地经营规模在不同地形梯度上的分布特征进行了研究。结果显示:1)奉新县全县49 891户农户的平均耕地规模为6.31块/户和0.66 hm~2/户,80%以上的农户为小规模经营。2)农户耕地经营规模受地形因素影响显著,两者呈负相关性关系。3)耕地承包地块数在10块以上或者耕地承包面积在1 hm~2以上的农户,其耕地的分布指数都在地形位指数等级1的区域达到最大值,随着地形位指数的增加,主体地位迅速被农户耕地经营规模较小的所取代。4)不同等级的农户耕地承包地块数和承包面积在不同的地形上有着不同的优势分布区间。这些都为新形势下的农村土地工作提供重要参考与借鉴。
Based on the survey data of rural land contractual management right in Fengxin county, the distribution of cultivated land management scale in Fengxin county on different topographic gradients was introduced by using the method of mathematical statistics and GIS spatial analysis. Features were studied. The results showed as follows: 1) The average farmland size of 49 891 households in Fengxin County was 6.31 blocks / household and 0.66 hm ~ 2 / household, and 80% of them were small-scale operations. 2) Farmers’ cultivated land management scale is significantly affected by topographical factors, and the two are negatively related. 3) The distribution index of cultivated land of all the farmers whose cultivated land contracted parcels is more than 10 or whose cultivated land contracted area is more than 1 hm ~ 2 reaches the maximum in the terrain index grade 1 area. With the increase of terrain bit index, The dominant position was quickly replaced by the smaller scale of farming households. 4) Different types of farmland contracted land plots and contracted area have different advantages in different terrain distribution intervals. All of these provide important reference and reference for rural land work in the new situation.
