湖泊碳循环研究进展及研究方法

近年来,碳循环问题日益成为全球变化与地球科学研究领域的前沿与热点问题,其中陆地生态系统碳循环又是全球碳循环中最复杂、受人类活动影响最大的部分,湖泊生态系统是陆地生态系统的重要组成部分,在维护区域生态平衡和生物多样性保护等方面具有重要作用。由于全球湖泊面积迅速减少,湖泊生态系统正常的水循环和碳循环过程产生一定的变化,湖泊生态系统的演变也可能是全球大气CO2含量升高的一个不可忽视的因素,因此了解湖泊碳循环国内外研究进展及研究方法,对于研究湖泊碳循环对全球碳循环的作用有重要的意义。

RESEARCH PROGERSS AND METHODS OF LAKE CARBON CYCLE

In recent years,the carbon cycle problem is increasingly becoming a global change and earth science research frontier and hot issues.The land ecosystem carbon cycle is the most complex in the global carbon cycle,and lake ecological system is an important part of land ecosystem,which plays an important role in maintaining regional ecological balance and biodiversity protection.The water cycle and the carbon cycle process of lake ecological system has a certain change,due to decrease of the global Lake area.And lake ecosystem evolution,which may also be elevated CO2 content,is one of the important factors which can not be ignored.Therefore,it has important significance on the global carbon cycle in understanding lake carbon cycle research progress at home and abroad and its research methods.
