| 摘 要： | 笔者分析了川西米亚罗林区典型低效林经不同强度的抚育间伐后,对5种处理的2个土层(0 cm~15 cm,15 cm~30 cm)的土壤总有机碳、微生物量碳含量的变化进行了动态监测,并分析了土壤总有机碳和微生物量碳含量的季节变化。结果表明,5种处理的土壤总有机碳和微生物量碳含量均是上层高于下层;在观测的4个季节内,上层、下层土壤总有机碳均是夏季春季冬季秋季,土壤总有机碳含量的上、下层均值是F3F2F1F4CK;土壤微生物量碳含量均是秋季冬季春季夏季;土壤微生物量碳含量的上、下层均值表现为F3F2F1CKF4,而且30%的间伐强度样地土壤总有机碳含量和微生物量碳含量均最高。

| Abstract: | This paper monitored and analyzed the seasonal dynamic change of total organic C ,microbial biomass C in soil in 2 soil layers （0 cm~15 cm, 15 cm~30 cm） after 5 different thinning schemes in Western Sichuan Miyaluo typical inefficient forest area .The results showed that soil total organic carbon and microbial biomass carbon content after 5 thinning schemes were the upper higher than the lower .Observed in four seasons , in the upper and lower soil , total organic carbon both were summer＆gt;spring＆gt;winter＆gt;autumn, the mean total organic carbon content in the soil was F 3〉F2〉F1〉F4〉CK.Soil microbial biomass carbon content were autumn 〉winter〉spring〉summer.In upper and lower soil , mean soil mi-crobial biomass carbon content was F3〉F2〉F1〉CK〉F4, and the carbon content of soil was the highest in 30%thinning schemes sample plot . |
