摘要: |
该文利用基尼系数法定量分析了我国农用地等别差异程度,深化了对农用地分等成果的认识,结 论表明我国耕地基尼系数为0.2523。除台湾以外的其他31省份的耕地基尼系数处于0.0002~0.3481之 间。我国农用地等别差异程度较大,由低到高分为三级,则一级地区主要沿西南-东北方向分布,二级地 区主要分布在东北、东南以及西部的西藏和四川,三级地区集中分布在我国中北部,包括青海、甘肃、宁 夏、陕西、山西、河北6省。 |

Abstract: |
This study quantitatively analyzed the agricultural land grade differences using Gini Coefficient method. The results showed that the Gini Coefficient of cultivated land in China is 0.2523. The Gini Coefficients of cultivat- ed land in 31 provinces, except Taiwan, of China ranged from 0.0002~0.3481. The difference of Agricultural Land Grade of China was notable which can be divided into 3 classes according to the cultivated land Gini Coeffi- cients from low to high. The areas of first class distributed along Southwest-Northeast direction. The second one distributed in Northeast, Southeast, Xizang province and Sichuang province. The third one located in north central China, contain Qinghai province, Gansu province, Ningxia province, Shaanxi province, Shanxi province and He- bei province. |
