Description

technical field [0001] The invention relates to a large-scale soil carbon flux monitoring system and method, and belongs to the technical field of earth soil and atmospheric chemical monitoring. Background technique [0002] In order to solve the problem of climate warming, developed countries have promoted the establishment of a global carbon dioxide emissions trading system, referred to as the "carbon trading" system. It is a market-oriented environmental protection system that allocates carbon dioxide emission quotas to countries and puts the quotas on the market for trading, thereby reducing carbon dioxide emissions. [0003] The carbon trading market is developing very rapidly. For example, after the Kyoto Protocol came into effect in 2005, the global carbon trading market experienced rapid growth. In 2007, the global carbon trading volume jumped from 1.6 billion tons in 2006 to 2.7 billion tons, an increase of 68.75%. The turnover of carbon trading has grown very ra...
