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。
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
