摘　　要：地类图斑净面积计算是土地利用规划数据处理的必需工作,是计算各类用地规划控制指标的基础。尽管净面积计算的公式简单,但基于不同的GIS软件,计算步骤、算法和实现方法各异。本文针对土地利用规划的数据处理工作,对地类图斑净面积计算的相关问题进行了分析,对计算思路、线状地物数据处理等进行了详细介绍,提出了基于ArcGIS软件的计算方法和计算步骤,并设计了关键步骤的实现算法,在宁波市江北区土地利用规划数据建库工作中得到了应用。Net area calculation of land patch is the essential work of the land use planning data processing, and it is the foundation of calculating land planning control index. The calculation formula is simple, but there are differences in the calculation step, implementation method, and algorithm, based on different kind of GIS platform. In this paper, against the land use planning data processing, net area calculation of land patch has been deep analyzed, and gives a detailed in- troduction about calculation idea and linear feature data processing. Followed by calculation method and procedure based on ArcGIS is proposed, and the key implementation arithmetic is designed, which has been applied in the building of land planning database of Ningbo Jiangbei district.
