Spatial heterogeneity of soil microbial biomass in Mulun National Nature Reserve in Karst area

Abstract

C mic 、N mic 的自相关距离约为 50 m,随着滞后距离的增大,自相关函数逐渐向负方向增长,达到显著的负相关。 P mic 的 Moran忆s I 在滞后距大于 70 m 后反而增大,表现为正相关。 C mic / N mic 的 Moran忆s I 较小,在-0. 2-0. 2 之间波动。 C mic 、N mic 的空间分布具有 很高的相似性,呈凸型片状分布,坡中含量高且向两边递减。 P mic 表现为明显不同的分布格局,其在坡中上位和洼地含量较高。

Effects of microhabitat on rodent-mediated seed removal of endangered Kmeria septentrionalis in the karst habitat

“…The climate in this region is dominated by the mid-subtropical zonal monsoon and the averages annual air temperature is approximately 19.3 • C, ranging from −5 • C in January to 26.7 • C in July. The annual rainfall averages 920 mm with the highest amounts of rainfall occurring from June to September (Liu et al, 2012). The annual frost-free period lasts approximately 235-290 days, and the relative humidity is typically higher than 79% (Pan, Nai & Li, 2008).…”

Effect of Leaf Litter on Seed Survival of Kmeria septentrionalis in Karst Habitat

“…The annual rainfall averages at 920 mm, with the highest amount of rainfall occurring from June to September (Wang et al, 2020). The annual frost-free period lasts approximately 235-290 d, and the relative humidity is typically higher than 79% (Liu et al, 2012). The local vegetation is a mid-subtropical evergreen and deciduous broad-leaved mixed forest dominated by species such as K. septentrionalis, Lindera communis, Machilus pingii, and Loropetalum chinense (Wang et al, 2019).…”
