浅谈耕地图斑划分对耕地面积的影响

Discussion on Influence of Polygon Partition on Cultivated Land Area

土地调查中,要排除耕地里面小地物对耕地面积的影响。基于同一种计算方法、田坎系数和坡度图,图斑划分是影响耕地面积计算的主要因素之一。本文结合实际,分析探讨通过改变耕地图斑范围提高耕地面积计算精度的方法。

Polygon partition is one of the important factors to influence the calculation of cultivated land area in land survey based on the same calculation method,ridge parameter and slope map,excluding the influence of small features.The paper probes into the way of increasing cultivated land area calculation by changing the polygon sphere.
