基于因素修正的土地整理项目区耕地等别更新研究

Update for Cultivated Land Grading in Land Remediation Project Areas Based on Correction Factors

耕地质量更新主要是对耕地质量发生变化的耕地进行重新赋值和等别计算。通过对土地整理项目区的耕地的质量变化进行研究,根据农用地分等规程,对土地整理项目区耕地的质量更新进行了探讨,即在等别更新过程中不仅对耕地的分等因素进行了修正,而且根据土地整理后耕地的实际生产情况对耕地的土地利用系数和经济系数进行了更新。结果显示:在所选取9个样点中,耕地的自然质量等提高0.53至0.89个等别;利用等和经济提升更加明显,其中8号样点的利用等提高了1.07个等别,经济等提高了1.12个等别,提升最低的3号样点的利用等和经济等也分别提高了0.61,0.49个等别,反映了土地整理对耕地质量的提升作用。

Cultivated land quality update is to mainly reassign value and calculate grade of the changed culti- vated land quality. The update of the cultivated land quality in land remediation project areas was discussed in this paper according to the regulations of farmland classification and through the study on the quality change of the cultivated land, which is not only to correct the grading factors, but also to amend the land uti- lization and economic coefficient of cultivated land according to the of practical production of cultivated land after land remediation. The results showed that the physical quality increased by 0.53 to 0.89 in the selected 9 samples~ utilization quality and economic quality increased more apparently, the utilization quality of the 8th sample raised 1.07 and economic quality was 1.12, the 3th sample had the least promotion but its utiliza- tion quality and economic quality also raised 0.61 and 0.49, respcectivly, reflecting the promotion effect of land consolidation on farmland quality.
