田东县耕地质量空间分布特征研究

针对田东县耕地情况，以农用地分等成果为基础，通过补充调查，重新测算耕地质量等别，形成最新耕地质量等级成果，分析耕地质量空间分布特征。结果表明，田东县耕地质量利用等别分布在4～10等，耕地质量总体较好，高等地、中等地占全县耕地面积的73．33％，主要分布在平马镇、祥周镇、林逢镇和思林镇，低等地主要分布在那拔镇、朔良镇、印茶镇和作登乡。该研究结果与当地实际情况相符，可为国土资源管理及农业生产提供科学依据。

Research on Spatial Distribution Characteristics of Quantity of Cultivated Land in Tiandong County

Based on the achievements of cultivated land grade, we recalculated cultivated land quality in Tiandong County again by supplementary investigation, and got the latest achievements of cultivated land grade. Finally, the characteristic of the spatial distribution characteristics of cultivated land quality was analyzed. It is showed that the cultivated land utilization quality grade of Tiandong County is good overall and distributed between level 4 to 10. The high and medium land accounted for 73.33% of cultivated land area, which mainly distributed in Pingma, Xiangzhou, Linfeng and Silin towns. The low land mainly distributed in Naba, Shuoliang, Yincha towns and Zuodeng Village. The result shows that this distribution characteristics are consistent with local conditions and can provide scientific basis for the management of land resources and agricultural production.
