Keywords: 喀斯特地区,土壤养分,土壤微生物生物量,植被恢复类型
Abstract:
为了更好地理解西南喀斯特地区不同植被恢复方式下的土壤质量,对原始林(对照)、次生林、竹林、马尾松林和草地等5种植被类型的土壤化学和微生物生物量特征进行了调查。结果表明:受母岩碳酸盐的风化和淋溶作用的影响,土壤ph呈中性的水平;土壤有机碳(soc)、全氮(tn)、全磷(tp)、钙(ca)、镁(mg)、钾(k)和钠(na)含量分别分布在23.4～142、1.5～13.5、0.1～0.9、2.7～16.4、1.7～5.9、2.0～7.1、0.13～0.48g/kg之间;土壤无机态nh+4-n和no-3-n的含量分别分布在0.43～8.83和0.01～9.71mg/kg之间;土壤交换性ca2+、mg2+、k+和na+分别分布在10.32～33.41、0.57～5.58、0.05～0.34、0.02～0.03cmol/kg之间;土壤微生物生物量碳(mbc)及mbn和mbp的含量分别分布在388.3～3191.8、65.4～624.8和3.9～67.5mg/kg之间。不同的植被类型土壤化学性质和微生物生物量呈显著差异,原始林和次生林的土壤化学性质高于其他植被类型,土壤微生物生物量的含量差异也呈现同样的结果,与不同植被类型有机质的输入量有关。不同植被类型土壤化学性质与土壤微生物生物量之间呈显著的相关关系。总体而言,单一树种造林,尤其是马尾松纯林的营造将不利于土壤的恢复,植被的自然恢复对于喀斯特地区土壤质量的提高是一种有效的途径。
