【摘要】：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。
[Abstract]:Based on the investigation data of the right to contract management of rural land in Fengxin County, the topographic location index and distribution index are introduced by means of mathematical statistics and GIS spatial analysis. The distribution characteristics of cultivated land management scale on different topographic gradients of farmers in Fengxin County were studied. The results show that the average cultivated land scale of 49 891 households in Fengxin County is 6.31 blocks / household and 0.66 hm2 / household respectively. The results show that the average cultivated land scale of 49,891 households in Fengxin County is more than 80%. Small scale management. 2) the scale of farm land management is significantly affected by topographic factors, There was a negative correlation between the two factors. 3) the distribution index of cultivated land reached the maximum value in the area of topographic site index grade 1 when the number of contracted land blocks was more than 10 blocks or the cultivated land contracted area was more than 1 hm~2, and with the increase of topographic site index, the distribution index of cultivated land reached the maximum value in the region of topographic site index grade 1. The main position is replaced by the small scale of farm land management. 4) the number of contracted land blocks and the contracted area of farm land of different grades have different dominant distribution ranges in different terrain. These are all farmers under the new situation. The village land work provides the important reference and the reference.
