摘要： 针对工作实践中海量矢量数据需要进行裁剪的情况，文章提出了一种利用ARCGIS软件中的模型构建器工具进行处理的方法，把工作流分解为数据准备、迭代要素类图层裁剪、迭代多裁剪框裁剪3个部分。每个过程用模型构建器具体实现为ARCGIS工具，用迭代器工具迭代被裁剪要素和裁剪框，既可以批量处理数据，减少多次处理的繁琐，又可以人工干预流程，每个环节出问题都能随时查看原因并解决。文章还以批量裁剪地形图要素类工作空间为例，以图框为裁剪要素，示范了批量处理的具体过程。

Abstract: A batch processing method is put forward to clip huge amounts of data, with the ARCGIS tool model builder. The workflow is broken down into three procedure: data provision, iteration of clipping feature classes and iteration of clipping frame. Each procedure is implemented by model builder tool. The Iterate Feature Classes tool and Iterate Feature Selection tool are used during the course. Massive data can be handled and trouble can be saved. At the same time, manual intervention is available if it is needed, and the problem can be examined at any time. The procedure of clipping topographic map features is studied as an example.
