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F3>F2>F1>F4>CK;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F3>F2>F1>CK>F4,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。

摘  要:
This paper monitored and analyzed the seasonal dynamic change of total organic C,microbial biomass C in soil in2 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 > spring > winter > autumn,the mean total organic carbon content in the soil was F3 > F2 > F1 > F4 >CK. Soil microbial biomass carbon content were autumn > winter > spring > summer. In upper and lower soil,mean soil microbial biomass carbon content was F3 > F2 > F1 > CK > F4,and the carbon content of soil was the highest in 30% thinning schemes sample plot.
