摘　　要：本文以重庆市开州区为研究区,基于森林资源专项调查小班数据,采用生物量模型估算植被的碳储量,采用土壤容重与含碳率估算表层土壤的碳储量,同时结合气象参数,模拟碳储量在一年中的季节性波动趋势。经计算,开州区2022年植被与土壤碳储量总量为2 163.44万t,夏季最高冬季最低,温度与生物量在一定范围内呈正相关,超阈值后转负相关。This paper takes Kaizhou District of Chongqing City as the study area,based on the sub-compartment data from a special survey of forest resources,employs biomass models to estimate the carbon storage of vegetation,it also utilizes soil bulk density and carbon content to estimate the carbon storage of surface soils,additionally,meteorological parameters are integrated to simulate the seasonal fluctuation trends of carbon storage throughout the year.Calculations reveal that the total carbon storage of vegetation and soil in Kaizhou District in 2022 amounted to 21,634,400 tons,in a certain range,biomass demonstrats a positively correlated with temperature,beyond the threshold,they become negatively correlated.
