摘要/Abstract

摘要： 选择伊春地区白桦林和兴安落叶松林近期（火后1年）轻度火烧迹地为研究对象，采用氯仿熏蒸浸提法分别测定两种典型林型在不同月份（6月、8月、10月和12月）火烧与未火烧区域土壤微生物生物量碳（C_mic）和氮（N_mic）的含量，并研究火干扰后C_mic和N_mic与土壤养分因子的关系。结果表明：白桦林火烧区域C_mic的总平均值低于未火烧区域，而N_mic的总平均值有所增加。与未火烧区域相比，火干扰后白桦林C_mic含量在各月份均无显著性差异（P>0.05），6、8、10和12月火烧（未火烧区域）C_mic含量平均分别为：1 389.6（1 247.2）、886.7（759.0）、1 098.9（1 052.6）和1 421.4（1 749.7） mg·kg^-1。而N_mic含量在6、8和10月显著增高（P<0.05），N_mic含量平均分别为：214.5（143.4）、101.9（67.5）、119.6（89.4）和150.2（183.3） mg·kg^-1。土壤含水量对C_mic和N_mic影响显著，N_mic与土壤pH值呈显著正相关。与未火烧区域相比，火干扰后兴安落叶松林C_mic和N_mic的总平均值均有所减少。火烧与未火烧区域C_mic和N_mic含量在各月份均无显著性差异（P>0.05），6、8、10和12月火烧（未火烧区域）C_mic含量平均分别为：689.7（695.9）、612.3（910.4）、361.6（474.7）和1 288.5（1 353.8） mg·kg^-1，而N_mic含量平均分别为：105.7（124.4）、91.4（111.4）、44.0（76.9）和118.9（134.5） mg·kg^-1。C_mic和N_mic与土壤含水量呈显著正相关，与土壤pH值呈显著负相关。白桦林火烧区域土壤含水量和土壤pH的总平均值高于未火烧区域，而土壤有机碳和土壤全氮的总平均值有所减少。与未火烧区域相比，火干扰后兴安落叶松林土壤含水量和土壤pH的总平均值低于未火烧区域，而土壤有机碳和土壤全氮的总平均值有所增加。

Abstract: In the burned area of Betula platyphylla and Larix gmelinii forests shortly after the fire in Yichun, we used the chloroform fumigation extraction method to examine the content of soil microbial biomass carbon(C_mic) and soil microbial biomass nitrogen(N_mic) from the two forest types in different months(June, August, October and December). We explored the relationship between C_mic and N_mic, and the influencing factors including soil water content, soil pH, soil temperature, soil organic carbon and soil total nitrogen after the fire. The overall mean C_mic of the burned plots was lower than that in the unburned plots, and the overall mean N_mic was increased after the fire in B.platyphylla. Compared with the unburned plots, C_mic had no significant effect in different months shortly after the fire, the mean C_mic in June, August, October and December in the burned plots(unburned plots) was 1 389.6(1247.2), 886.7(759.0), 1 098.9(1 052.6) and 1 421.4(1 749.7) mg·kg^-1, respectively, yet the N_mic was significant higher than that in the unburned plots in June, August and October with the mean N_mic of 214.5(143.4), 101.9(67.5), 119.6(89.4) and 150.2(183.3) mg·kg^-1, respectively. The soil microbial biomass was positively correlated to the soil water content, and N_mic was influenced by soil pH significantly. Compared with the unburned plots, the overall mean C_mic and N_mic of the burned plots were lower than those in L.gmelini. The soil microbial biomass had no significant effect throughout different months of L.gmelinii. The mean C_mic in June, August, October and December in the burned plots(unburned plots) was 689.7(695.9), 612.3(910.4), 361.6(474.7) and 1288.5(1353.8) mg·kg^-1, respectively, and the mean N_mic was 105.7(124.4), 91.4(111.4), 44.0(76.9) and 118.9(134.5) mg·kg^-1, respectively. C_mic and N_mic were significantly positively correlated with soil water content, but negatively with soil pH. The overall mean soil pH ,soil organic carbon and soil total nitrogen of the burned plots were higher than the unburned plots, yet oil water content was decreased in Betula platyphylla. The overall mean soil pH ,soil organic carbon and soil total nitrogen of the burned plots were lower than that in the unburned plots, however, soil water content was increased after the fire in L.gmelinii.
