摘要
本文研究了浙江省马尾松（Pinusmassoniana）林土壤呼吸速率与土壤温度的关系，建立土壤呼吸速率与地表温度的模型，根据气象资料估算得到马尾松林的年均土壤CO2呼吸量为25．33tCO2·hm-2a-1，浙江省马尾松林每年土壤CO2排放量为3．60×107tCO2·a-1．
This paper studies the relation between soil respiration and soil temperature of Pinus massoniana forest in Zhejiang province.By establishing the model of soil respriational rate and soil surface temperature,We conclude in the light of meteorological data that the average soil respiration amount of P.massoniana forest in a year is 25.33 tCO2·hm-2·’a-1,the annual amount of CO2 released from the soil of P. massoniana forest in Zhejiang province is 3.60×107 tCO2·a-1
