萨拉乌苏河流域150 ka BP 以来的粒度旋回 [PDF]
, 2001 萨拉乌苏河流域米浪沟湾地层剖面150 ka BP 以来古流动砂丘砂与河湖相和古土壤在粒度上具有多次显著的粗细韵律交替变化, 粒度参数- M z、R、Sk、Kg 和SC/ D 亦随之响应为多波动峰谷交替的态势。同时, 粒度特征值- 5 5、5 16、5 25、5 50、5 75、5 84、5 95 相应地表现为非常有节奏地跳动。据此, 将米浪沟湾剖面划分为27 个粒度粗细沉积旋回, 并认为其是150 ka BP 以来在东亚冬夏古代季风交替影响下沙漠演变的一个颇为完整的气候- 地质过程记录。The ...

On the normative roles of biodiversity and naturalness in conservation
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Nature is an opaque concept. Consequently, the term biodiversity conservation has replaced nature conservation in most conservation contexts. We review the conceptual indeterminacies that plague the terms nature and natural but then show that comparable difficulties plague biodiversity.
