Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Primates, 69% of which are threatened with extinction, are the third most specious order of mammals. We used primates as model taxa to examine the umbrella effects of primates on ecosystem services and the protection of other vertebrates and seed plants in Yunnan Province, China.

Shuitu Baochi Xuebao, 2002 土壤水分有效性的高低是制约石渣土生产能力的关键因素之一。对丹江口库区郧县石渣土 3种不同土石比土壤水分有效性的研究表明 :土壤水分有效性与土壤中的土 (<2 mm)石 (>2 mm)比关系密切。土壤蒸发、持水、导水和供水能力均与土壤中的土石比的大小有关。 3种土壤的持水能力 ,以石砾含量较少、质地较粘的土壤最强 ,以石砾含量较多、质地为壤质的土壤最低。而土壤水分蒸发能力与砾石含量呈负相关 ,土壤水分扩散率则与砾石含量呈正相关。适中土石比的土壤可提高入渗性能 ,减少蒸发量 ,提高供水性能。

Shuitu Baochi Xuebao, 2021 为探究微塑料对土壤持水性能的影响，选用粒径为1 mm和25 μm的聚乙烯微塑料（PE—MPs）颗粒进行土培处理后，采用高速离心机法测得不同处理下的土壤水分特征曲线，并使用Gardner模型进行拟合分析。结果表明：（1）土壤中累积少量的PE—MPs （0~5.00 g/kg）能增强土壤持水性，但当累积量超过一定阈值（5.00~50.00 g/kg）会导致土壤持水能力显著降低。（2）1 mm大粒径PE—MPs大量积累对土壤持水性的降低效应更显著；25 μm小粒径PE ...

Integrative Conservation, Volume 4, Issue 3, Page 362-380, September 2025.Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

Shuitu Baochi Xuebao, 2005 杂交狼尾草是一种优良的多年生禾本科牧草,具有很好的水土保持能力,但人们对其水土保持方面的定量研究较少。通过对杂交狼尾草草地植被的持水能力、土壤水分变化、土壤抗冲性、渗透性等指标的研究,探讨杂交狼尾草的水土保持能力。结果表明:杂交狼尾草的持水能力强,能明显增加土壤水分含量,提高土壤的抗冲性、渗透性,在三峡库区的水土保持工作中有着广阔的应用前景。
