总体来看，皆伐林地土壤呼吸对一年的氮沉降响应表为由初期促进土壤CO2的排放，到中期逐渐抑制土壤呼吸速率，最后降低土壤CO2排放。

Overall , forest clear-cutting on soil respiration in response of nitrogen deposition shows that in the early time the nitrogen deposition can promote soil CO2 emissions , at later it has a gradual inhibition of soil respiration rate , and ultimately to reduce CO2 emissions from soil .
