摘　　要：为解决常规的矢量同名图层合并方法效率低、容易遗漏等问题,利用ArcGIS模型构建器分别创建了基于迭代要素类、迭代字段值、迭代行选择3种迭代器的同名矢量图层合并模型,实现了批量准确地矢量图层合并。介绍了关键工具,阐述了模型的创建思路及方法。结果表明:指定图层的合并可使用任意批量合并工具,效率相当且高效;所有同名图层的合并使用“迭代行选择”的方法效率最高,较使用“迭代要素类”的方法效率提升32.7%,较使用“迭代字段值”的方法效率提升21.9%。迭代行选择的方法在一定程度上可替代迭代字段值。创建的模型便于移植与共享。To solve the problems of low efficiency and omission in conventional vector layer merging methods,ArcGIS model builder is used to create vector layer merging models with the same name based on three iterators:iterators-feature classes,iterators-field values,and iterators-row selection,achieving batch and accurate vector layer merging.The key tools are introduced,and the idea and flow chart of model creation are described.The results indicate that the merging of specified layers can be efficiently accomplished using any batch merging tool,with comparable and high efficiency.The merging of all layers with the same name using the"iterators-row selection"method is the most efficient,which is 32.7%more efficient than the"iterative feature class"method and 21.9%more efficient than the"iterative field value"method.The iterators-row selection method can,to some extent,replace the iterators-field values method.The created model is convenient for transplantation and sharing.
