海河流域碳、氮、硫、磷及生态环境数据库
- AN ECO-ENVIRONMENTAL DATABASE SYSTEM FOR C,N,S,AND P B10GEOCHEMICAL CYCLING IN HAIHE RIVER BASIN
- 摘要:介绍了海河流域碳、氮、硫、磷及生态环境数据库的建库目标,指导系统分解的概念模型,选择录入数据的指标体系,数据库系统构成及所含6个子库典型输出表。做为数据库的必要功效补充,还建立了地理信息系统。整个数据库系统是在DBASE-Ⅲ、汉化地理信息系统工具和FORTRAN-77统计与模式程序包支持下,在PC/AT微机上实现的。
- Abstract:The object analysis, the concept model, the index system and the system components of an eco-environmental database system for C, N, S and P cycles in Haihe River basin of China are introduced in this paper. The six sub-database are also illustrated. The whole system was developed using dBASE Ⅲ, Chinese-CIS tool and FORTRAN-77 statistical package on a PC/AT microcomputer. A geographical information system (GIS) was also attached to the system as an essential complement of the database.
