摘　　要：三调工作的开展是为了满足新形势下新的工作需求,在对三调图斑数据进行空间统计时实现不同分类的级联统计以全面掌握土地利用现状特点是有必要的。首先研究设计了以<工作分类地类编码,[一级分类索引,三大类索引]>为键值对的HashMap存储三调工作分类和一级类、三大类的级联关系,实现级联编码索引,然后设计开发了基于Web服务的API实现给定空间范围内三调图斑数据的级联统计,最后模拟实验数据验证了模型的有效性,可为三调图斑数据的相关统计分析提供服务支持。The third national land survey was carried out to meet the new work needs under the new situation.It is necessary to realize the cascade statistics of different classifications in order to fully grasp the characteristics of land use status.First of all,the paper use the HashMap data structure to store the cascading relationships of different classifications,which the k-v pair based on the entity of,then designs and develops the WEB service API to realize the cascading statistics of the data in a given space range,and finally simulation data are used to verify the validity of the model.This study can provide service support for relevant statistical analysis.
