摘要：

为寻求一种比较方便、快捷，高精度的地图缩编的解决方案，结合县域耕地资源管理信息系统建设项目，在ArcMap平台下，采用其二次开发接口ArcObjects组件为基础工具，拓展实现了1:10000比例尺到1:50000土地利用现状图斑的快速、有效、高效缩编，主要涉及土地利用现状图的细小多边形（面积不足上图面积的多边形）合并，狭长地物（宽度不够上图单元的多边形）的破碎和合并两个模块。结果表明，该两个模块能够在保证土地利用现状图图斑缩编质量的同时，很大提高工作效率，提高了作业精度。为1:10000到1:50000土地利用现状图图斑缩编的实现提供了重要的参考和方法。

Abstract:

In order to seek a more convenient, fast, high accuracy map generalization solution, the author used the second development interface of ArcObjects component to come true the fast, effective and high efficiency shortening the map size of land use from 1:10000 to 1:50000 by use ArcMap soft based on county cultivated land resources management system construction project. It refers to two aspects, that is, small polygon aggregation and narrow features broken and merger. The result shows work efficiency increasing and precision improving, and these two aspects herein ensure the higher quality of map generalization of land use as well. It can be recommended as an important reference and good methods to realize the map generalization of land use from 1:10000 to 1:50000.
