城市植被碳汇研究方法及进展

Researching methods and development of plant carbon storage in urban areas

全球气候变暖是目前世界广泛关注的一个问题,大气中的CO2增加导致的温室效应正深刻影响着人类的发展,开展碳循环过程中源与汇的研究是有效解决温室效应的基本思路,植物碳储能力研究是其中的重要内容之一,城市碳汇作为陆地生态系统碳储能力的一部分正成为一个新的热点。文章围绕城市植被碳汇研究,对碳汇概念、不同类型植物碳汇研究方法作了概要介绍,阐述了城市植物碳汇研究现状,并对城市碳汇研究做了展望。

Global warming is a problem worldwide concerned. The greenhouse gas effect resulted from increased CO2 in the atmosphere has profoundly influenced the development of human beings. The study of carbon sources and sinks in the course of carbon cycle is a main method for solving this problem effectively. The plant carbon storage capacity in urban areas is part of carbon storage of terrestrial ecosystem. At first we introduced the con- cept of carbon storage, the research status and researching methods for different type of vegetation. Then we ex- plored the situation of carbon sink in urban vegetation, and put forward the key issues about the carbon storage in urban ecosystem.
