【摘要】：在奉新縣農(nóng)村土地承包經(jīng)營(yíng)權(quán)確權(quán)調(diào)查資料基礎(chǔ)上,利用數(shù)理統(tǒng)計(jì)法和GIS空間分析法,引入地形位指數(shù)和分布指數(shù),對(duì)奉新縣農(nóng)戶的耕地經(jīng)營(yíng)規(guī)模在不同地形梯度上的分布特征進(jìn)行了研究。結(jié)果顯示:1)奉新縣全縣49 891戶農(nóng)戶的平均耕地規(guī)模為6.31塊/戶和0.66 hm~2/戶,80%以上的農(nóng)戶為小規(guī)模經(jīng)營(yíng)。2)農(nóng)戶耕地經(jīng)營(yíng)規(guī)模受地形因素影響顯著,兩者呈負(fù)相關(guān)性關(guān)系。3)耕地承包地塊數(shù)在10塊以上或者耕地承包面積在1 hm~2以上的農(nóng)戶,其耕地的分布指數(shù)都在地形位指數(shù)等級(jí)1的區(qū)域達(dá)到最大值,隨著地形位指數(shù)的增加,主體地位迅速被農(nóng)戶耕地經(jīng)營(yíng)規(guī)模較小的所取代。4)不同等級(jí)的農(nóng)戶耕地承包地塊數(shù)和承包面積在不同的地形上有著不同的優(yōu)勢(shì)分布區(qū)間。這些都為新形勢(shì)下的農(nóng)村土地工作提供重要參考與借鑒。
[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.
