滇中尖山河流域不同土地利用类型土壤抗蚀性

open access: yesShuitu Baochi Xuebao, 2019
为揭示滇中尖山河小流域不同土地利用类型的侵蚀特性,以滇中尖山河小流域4种不同土地利用类型(坡耕地、裸地、林地、园地)不同土层(0-10,10-20,20-30 cm)土壤为研究对象,通过对土壤抗蚀性15个指标的测定与分析,研究了不同土地利用类型对土壤抗蚀性的影响。结果表明:不同土地利用类型中坡耕地、裸地>5 mm土壤水稳性团聚体显著低于林地、园地,>5 mm水稳性团聚体含量表现为裸地(12.72%)大于坡耕地(8.93%),且坡耕地>0.25 mm团聚体随土层深度的增加而降低 ...

A Comparison of the Effects of Habitat Type and Human Influence on Occupancy of Freshwater Turtles in the Mississippi Embayment 栖息地类型与人类影响对密西西比湾淡水龟分布影响的比较

open access: yesWildlife Letters, Volume 3, Issue 2, Page 46-55, June 2025.
Pond and riverine turtles respond to land‐use in similar ways being sensitive to increased exposure to roads but resilient to agriculture. ABSTRACT Freshwater turtles are highly diverse in the southeastern United States, yet few studies document how diversity is distributed in agricultural and rural landscapes.

长春市土壤侵蚀潜在危险度分级及侵蚀背景的空间分析

open access: yesShuitu Baochi Xuebao, 2007
在ARCG IS 8.3地理信息系统(GIS)支持下,实现了土壤侵蚀潜在危险的分级及其空间分析。首先,采用美国通用土壤侵蚀模型估算土壤侵蚀量,再用土壤年均侵蚀量、土层厚度和土壤容重得到土壤抗蚀年限图,按水利部标准将长春市土壤侵蚀潜在危险度分为5级,并提出了土壤侵蚀潜在危险指数的概念。借助GIS方法,通过分析不同坡度、不同坡向、不同地貌类型以及不同土地利用类型等背景条件下的土壤侵蚀潜在危险度情况,探讨了土壤侵蚀潜在危险度的空间分布特点。

海州露天煤矿排土场复垦区不同土地利用类型土壤入渗特征

open access: yesShuitu Baochi Xuebao, 2017
为揭示排土场复垦区不同土地利用类型土壤的水源涵养功能,采用野外实地双环入渗试验和室内理化分析方法,系统地研究了海州露天煤矿排土场复垦区不同土地利用类型(乔木林地、灌木林地、农用地、荒草地)土壤入渗特性及其影响因素。结果表明:不同土地利用类型下的土壤初始入渗率、稳定入渗率和累计入渗量均表现为乔木林地>灌木林地>农用地>荒草地;不同土地利用类型下土壤入渗过程的拟合优度存在差异,G-P综合模型、Kastiakov模型、Horton模型的平均拟合优度依次为0.926,0.908,0.905。G ...

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition

open access: yesAntipode, Volume 57, Issue 3, Page 830-861, May 2025.
Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

Conservation Gap Within a Nature Reserve: A Case Study in the Biodiversity Hotspot of Rare and Endangered Plants at the Southern Gaoligong Mountains 高黎贡山南段稀有濒危植物保护空缺分析

open access: yesIntegrative Conservation, Volume 4, Issue 1, Page 71-84, March 2025.
Gaoligong Mountain is home to a large number of rare and endangered species, but the effectiveness of conservation measures in the Gaoligong Mountain Nature Reserve remains uncertain. We predicted the potential distribution areas of 361 rare and endangered wild plants in southern Gaoligong Mountain under current and future climate change scenarios and ...

A spatially explicit assessment of factors shaping attitudes toward African elephant conservation

open access: yesConservation Biology, Volume 39, Issue 1, February 2025.
Abstract Conservation plans that explicitly account for the social landscape where people and wildlife co‐occur can yield more effective and equitable conservation practices and outcomes. Yet, social data remain underutilized, often because social data are treated as aspatial or are analyzed with approaches that do not quantify uncertainty or address ...
