喀斯特原生天坑垂直梯度上植物多样性特征——以云南沾益天坑为例 [PDF]
, 2018 规模宏大的地表负地形——喀斯特天坑具有巨大的容积和陡峭圈闭的岩壁,在坑底形成异于坑外的独特微生境,是研究物种组成和多样性的理想场所,但目前鲜少对喀斯特天坑植物群落的生态过程及其空间变化特征进行探讨。本研究以云南沾益大毛寺原生天坑植物群落为研究对象,通过游动分割窗技术以及边缘效应值、边缘效应强度和β多样性指数的计算,对原生天坑\"坑边缘—坑壁—坑底\"的生态交错带进行定量判定,探讨垂直环境梯度上植物群落物种多样性变化特征及天坑内外物种多样性边缘效应特征。研究结果表明,原生天坑\"坑边缘—坑壁—坑底 ...

Shuitu Baochi Xuebao, 2021 为揭示荒漠草原区域围封对不同土壤生境物种多样性和功能多样性的影响，以荒漠草原不同土壤生境下围封（15年、10年、6年）和放牧（15年、6年、5年）的草地植物群落为研究对象，基于方差分析和主成分分析的基础上，通过函数拟合分析，探讨植物物种多样性与功能多样性之间的关系。结果表明：（1）围封相对于自由放牧条件，灰钙土生境植物功能多样性显著增加（P0.05）。（2）功能离散度表征的功能多样性与物种丰富度关系可用二次多项式Y=aX2+bX+c形式表示，随着封育年限的增加 ...
