中文摘要: 空间相似关系作为空间关系的一种,其研究目前还处于比较初始的阶段。对空间相似关系及群组目标相似性度量模型进行研究,将会促进空间关系理论的研究和完善,促进和深化空间认知,提高空间数据智能化和自动化处理水平等重要意义。本课题针对空间群组目标的相似度计算模型展开研究,拟(1)研究空间相似关系的基本概念模型,包括其定义和内涵、分类体系、基本性质等;从空间数据本身特点以及人们的认知习惯出发,建立影响空间群组目标相似度的特征因子的"一般集合"。(2)研究面向空间相似关系的空间群组目标的描述和形式化表达方法;在对空间群组目标进行细分研究和描述的基础上,将(1)中的"一般集合"进行"具体化"。(3)在对影响空间群组目标相似度的各特征因子进行提取及合理权值分配的基础上,最终建立空间群组目标相似度计算模型。

英文摘要: As a kind of spatial relationship, spatial similarity relationship is still in its initial research stage.Research works of similarity assessment of spatial group objects will promote and improve spatial relationship's theory, promote and deepen spatial cognition and raise the level of spatial data intelligent and automated handling.This research project focuses on the similarity model of spatial group objects,and proposes the following three contents: the first content is to conduct research on the basic concept model of spatial similarity relationship,including its definition,basic characteristics and its classification system; The research is conducted to establish the "common collection" of feature factors which influence the simialrity assessment of spatial group objects according to the characeristics of spatial data, people's cognitive habits. The second content is to conduct research on spatial similarity relationship oriented formal decription of spatial group objects based on segmentation research and description of spatial group objects and the "common collection", which is metioned in the first research content and will be reificationed. The third research content is to eventually establish a similarity assessment model of spatial group objects based on feature extraction and proper weights distribu
