摘要: 组建地理信息系统数据库是进行种群时空动态分析的前提和基础。在介绍地理信息系统数据库的概念、特点等的基础上,以ArcView GIS 3.1作为组建数据库、进行时空分析的基本软件平台,对浙江省水稻二化螟数量变化的历史资料及有关的空间和属性数据进行分类、编码、输入与编辑等, 分别建立了空间及属性数据库。其中空间库包括浙江省的政区、河流、道路、等高线、土壤类型等图层, 属性库包括气象、耕作制度、灯诱及田间数据等。并将各地地名作为主关键字,以实现空间库与属性库以及各属性库之间的关联。该数据库不仅具有基本的数据库管理功能,如数据的输入、输出、编辑和查询,更重要的是可以通过该数据库对种群动态进行时空分析。

Abstract: It is the precondition and foundation to build GIS database for analysis of population spatio-temporal dynamics. Based on introduction to the conception and feature of GIS database, ArcView GIS 3.1 was used to develop database for Chilo suppressalis in Zhejiang Province. The database, which includes spatial and corresponding attribute database, was built by classifying, coding, inputting and editing original data, etc. The spatial database comprised the boundary map, river map, road map, contour map and soil category map of Zhejiang Province, etc. and the attribute database included meteorologic, cultivated, light trapping and field sampling data, etc. We use place name as the primary key word to build the relationships between the spatial database and attribute database or each attribute tables. The database will be able to provide powerful assistance for pest managers in spatio-temporal analysis, besides the basic database management functions, such as data inputting, outputting, editing and querying.
