摘要:湿地碳循环研究对全球变化具有重要意义,通过研究湿地生态系统中碳循环过程,可
以了解不同类型湿地在碳源/汇过程中的作用。本文以 visual studio 2008 为开发平台,利用
ArcEngine 二次开发技术,通过分析崇明湿地碳源/汇模拟和管理的需求,建立崇明湿地碳
源/汇模拟系统。该系统具有空间数据和关系数据的管理和查询、碳源/汇指标数据模拟、专
题图的绘制以及数据的可视化表达等功能,为研究湿地生态系统碳循环与 GIS 技术的结合
做出了一次成功的探索。

Abstract: The research on wetland carbon cycle is of great significance to global climate change.
Through the research of carbon cycle in different wetland ecosystems, this paper study the effects
of different wetland ecosystems in global carbon on visual studio 2008 development
platform, using ArcEngine repeated development technology, through the analysis of the need of
Chongming wetland carbon management, Chongming wetland carbon source/Sink simulation
system was established. This system can be used to query and manage spatial data and relational
data, and there are different ways to view the simulation results. This paper make a essful
exploration for bination of GIS and wetland ecosystem carb
