川西亚高山云杉低效林林窗改造下土壤水溶性有机碳的季节动态

Seasonal Dynamics of Soil Water Soluble Organic Carbon in Forest Gaps of the Low Efficiency Spruce Plantation in the Subalpine Region of Western Sichuan

  • 摘要: 本文分析了川西亚高山米亚罗林区典型云杉低效林经不同面积的林窗(50 m2,L1;100 m2,L2;150 m2,L3;对照样地,CK)改造后土壤总有机碳和水溶性有机碳含量的变化。对4个样地的不同土层(分0~15 cm,15 cm~30 cm两层)的土壤总有机碳和水溶性有机碳的变化进行了动态监测,并分析了土壤总有机碳和水溶性有机碳的季节变化及与其他活性碳和土壤温度的关系。结果表明:土壤总有机碳和水溶性有机碳的含量均是L2 > L3 > L1 > CK,且土壤上层高于下层;在观测的四个季节内,上、下层土壤水溶性有机碳含量均是夏季最低,以后逐渐升高,100 m2林窗的碳含量最高。

     

    Abstract: In this paper,analysis was made of the content changes of the soil organic carbon and water soluble organic carbon through different gaps (50 square meters,L1;100 square meters,L2;150 square meters,L3;control plot,CK) in typical low-efficiency spruce forest gaps of Miyaluo forest area in Western Sichuan.Dynamic monitoring was conducted on changes in soil organic carbon and water soluble organic carbon in four plots in different soil layers (0~15 cm and 15 cm~30 cm layers),and analysis was made of seasonal variation of soil organic carbon and water soluble organic carbon and thier relationship with other activated carbon and soil temperature.The results showed that total organic carbon and dissolved organic carbon content of the soil were L2 > L3 > L1 > CK,and those of the upper layer of soil were higher than those of the lower layer.In four seasons observations,water-soluble organic carbon content in the upper and lower layer soil was the lowest in summer,then gradually increased,and the carbon content of 100 square meters of forest gap was the highest.
