摘要

继续深入研究我国耕地定级

对区域耕地的数量、质量等的评价以及更好地保护和利用土地资源具有重要的现实意义。采用高分辨率的QuickBird遥感影像

提出了不同于传统农地定级的技术路线

通过高通滤波融合、几何校正

建立了地物解译标志和屏幕矢量化分类生成土地利用现状图

提高了大比例尺制图效果

并制作出了1:2000比例尺耕地定级质量图。

Abstract

Arable land gradation

a further step of the finished agricultural classification

has a great signifi-cance to the evaluation of arable land quantity and its quality

as well as the protection and utilization of land resources. High resolution QuickBird images are used and a novel strategy different from the traditional gra-dation of farmland is proposed by adopting high-pass filtering fusion method in spatial domain and geometric correction. Accordingly

object interpretation symbols and screen vectorization classification are established to make a real time land utilization map. The effect of large-scale mapping is improved and a map of arable land quality gradation is made at a scale of 1:2000.
