Analysis of the Impact of Soil Simulation Warming Devices on Carbon Emission Monitoring
Under the global warming environment,minor changes in soil carbon will have large impacts on the carbon cycle in terrestrial ecosystems,which in turn positively feedbacks on the future climate warming.Currently,many field experiments on the in-situ simulation of warming have been carried out worldwide,mainly focusing on the soil carbon emission and soil microbial response to warming.During the research process,the effect of different warming devices,warming times and locations of warming experiments cannot be ignored.Based on the related re-search results of the global climate change,this paper summarized some commonly used warming device settings and characteristics,and results of this study show as follows.(1)Active warming is more effective than passive warming due to the controllability of active warming devices and the better warming effect.(2)Most warming exper-iments last for 1～5 years and the effect of warming devices is only limited to the shallow-soil,and therefore long-term and deep-soil warming experiments should be carried out in the future.(3)Most warming experiments are concentrated in mid-high and high altitude areas of the northern hemisphere,and more field in-situ warming experi-ments can be conducted in tropical subtropical areas in the future.(4)Warming,nitrogen deposition,rainfall changes,and CO2 doubling experiments should be combined in the future to investigate the effects of interactions amongdifferent global change factors on the carbon cycle in terrestrial ecosystems.This work provides method in-struction for the global climate change in the future,and is of important scientific significance.
