Conservation Biology, EarlyView.Abstract The sustainability of area‐based conservation initiatives depends on their value to society. Conservation often focuses inside protected areas, but the impacts of protected areas beyond their boundaries (spillovers) are critical for their social license.

, 2014 不同的自然、历史条件与社会经济背景使得区域旅游系统空间结构各不相同.借助旅游经济模型讨论了区域之间的旅游经济联系强度和旅游经济联系隶属度.研究表明,新疆各地区之间的旅游经济联系很不均衡,乌鲁木齐和昌吉地区构成强联系区,其它地区和城市构成一般联系区;强联系区的容量维和信息维均小于一般联系区,表明旅游景区数量在各地区间的分布变差相对较小,景区分布相对较均衡;一般关联区旅游景区系统的容量维和信息维数值偏大,说明旅游景区数量在各地区间的分布变差相对较大 ...

Optimizing biodiversity offsetting for habitat succession and colonization dynamics
Conservation Biology, EarlyView.Abstract Biodiversity offsetting aims to compensate for ecological losses from development through conservation and restoration. However, its long‐term outcomes under repeated impact–offset cycles remain uncertain. Using a conceptual forest succession model, we evaluated how offset outcomes are affected by interactions among compensation scale ...

面向工程应用的先进绝热压缩空气储能模型及先进㶲分析 [PDF]
全球能源互联网先进绝热压缩空气储能（advanced adiabatic compressed air energy storage system，AA-CAES）仿真建模及分析是其工程实践的基础。然而，目前模型一般基于理想工况建立，分析结果与实际工况相偏差较大，无法指导工程应用。为此，在传统热力学模型基础上，考虑了空气流动阻力损失和能量转换设备损耗等因素，建立了面向工程应用的AA-CAES模型并以200 MW盐穴AA-CAES系统为例进行了分析。同时，对系统效率分析方法进行改进并对其进行了先进分析。结果表明 ...

Pest‐preservation paradox among insects
Conservation Biology, EarlyView.The pest‐preservation paradox is a non‐binary perspective that insects range from those that are harmful and requiring management on the one side, to those requiring conservation intervention on the opposite end of the spectrum. Importantly, the vast majority of insects occur somewhere in the center of the two extremes, and their position along the ...

, 1996 赣东北地区共有鱼类１３５种和亚种，隶属于１０目２２科８０属。其中纯淡水鱼类１２８种和亚种，占总数的９４．８％。鲤形目是最主要鱼类群，有９５种和亚种，占纯淡水鱼类的７４．２％。鲤科鱼类最丰富，有８０种和亚种，占纯淡水鱼类的６２．５％。此地区鱼类区系以东亚特有的江河平原鱼类为其主要组成成分，此外，既有老第三纪原始类群的后裔种类，又有南亚暖水性类群鱼类，而且全北区冷水性类群鱼类也分布于此。与邻近水系比较，此地区与赣江水系、钱塘江水系和湘江水系的鱼类区系无显著差异 ...

Synthesis of Pollinator‐Friendly Management in European Protected Areas
Conservation Biology, EarlyView.Effectiveness of pollinator‐friendly management in European protected areas. Abstract Pollinators are important to humans and nature due to their role in ecosystem functioning and services. Research on the effects of pollinator management in protected areas is insufficient compared with that on farmlands and urban areas, potentially hindering ...
