基于GIS的我国近海外来生物入侵时空演变数据库系统构建方案研究

海洋生物入侵已成为世界海洋生态环境面临的四大问题之一。我国目前针对海洋外来生物入侵的数据资料缺乏,且未形成时空分布的数据系统。本文通过文献查找、资料收集与历史数据整理,现场调研等多种手段,拟掌握我国近海外来生物入侵时空演变历史及现状,提出基于GIS软件的数据库系统的建设方案。本系统的建设可实现海洋入侵物种查询,外来入侵物种判定、不同时期下,外来生物入侵我国近海海域的发生地点、入侵种类、灾害发生时间、灾害影响的对比分析等功能。

Research on Construction Scheme of my country 's Near Overseas Biological Intrusion Temporal Evolution Database System Based on GIS

The invasion of marine organisms has become one of the four major problems facing the world marine ecological environment.At present,China is short of Data and information on the invasion of marine alien species.The unformed spatio-temporal data system of marine alien invasion in China.In this paper,by means of Literature Search,data collection and historical data collation,on-the-spot investigation and so on,the authors master the history and present situation of the invasion of exotic organisms in the offshore area of China,and put forward the construction scheme of database system based on GIS software.The construction of this system can realize the functions of marine invasive species inquiry and alien invasive species identification.It can also realize the comparative analysis of the place,species,time and effect of the alien invasion in different periods.
