闽江口湿地时空演变模型及信息系统

在动态度、马尔柯夫链等数学建模型和生态学理论、方法指导下建立闽江口湿地时空演变模型,设计了松散集成和紧密集成相结合的方式,集成湿地模型与GIS.应用组件式开发技术,利用MapObjects在V isual Basic平台上,进行闽江口湿地时空演变信息系统设计和开发,并应用该信息系统对闽江口湿地时空演变进行分析.研究表明,松散集成和紧密集成相结合的方式,在短时间和人力、财力缺乏条件下,较为理想地解决了湿地模型与GIS集成问题;而具有演变模型应用功能的信息系统,也以数字和图形形式大大提高了闽江口湿地变化分析的直观性与科学性.

Spatio-temporal evolution models and information system of the Minjiang River Estuary wetland

With the help of dynamic degree,Maerkefu chain mathematical methodology and landscape ecology theory,the spatio-temporal dynamic chang models of Minjiang River Estuary wetland are established.The wetland models and GIS are integrated with the way that weds loose coupled and tight integrated,Applying the COM technology,using MapObjects in Visual Basic platform,a specific GIS system for monitoring and management of the Minjiang River Estuary wetland has been developed in this research.A case of the application of the GIS system are showed.The research show that the combination of loose coupled and tight integrated is a ideal solution to the integrate of wetland models and GIS,in a short time,manpower and financial conditions.And the system could be more efficient,and can provided visual informations and vivid way to analysis wetlands,making the management and protection of Minjiang River Estuary wetland more scientific and convenient.
