黑河下游额济纳河沿岸绿洲是阿拉善独特的三道生态屏障——额济纳河沿岸绿洲、横贯东西绵延800多公里梭梭林带、贺兰山天然次生林之一。三道生态屏障同时也是我国西北地区的一条重要生态防线。但由于气候旱化和对动植物资源的不合理开发利用等因素的共同作用,目前黑河下游额济纳河沿岸绿洲生态功能退化严重,生态防护功能受损。为改善黑河下游额济纳河沿岸绿洲的生态环境状况,恢复额济纳绿洲生态功能,需要尊重自然规律,遵循生态学原理,在可持续发展原则指导下合理开发、利用自然资源,加大环保监管力度,综合运用经济、工程、法制、宣传等规划管理措施和手段加强生态环境保护与建设,保护额济纳绿洲生态屏障。 相似文献

Spillover and crossover of sex‐based harassment from work to home: Supervisor gender harassment affects romantic relationship functioning via targets' anger 下载免费PDF全文
Julian Barling 《组织行为杂志》2015,36(2):196-215
We investigate how gender harassment affects the romantic relationships (i.e., romantic relationship adjustment and romantic relationship efficacy) of female targets (spillover effects) and their romantic partners (crossover effects), and what role targets' anger in response to their gender harassment plays in these relationships. We explored these questions using two US samples. Sample 1 comprised 206 females, all of whom provided data on their gender harassment experiences, feelings of anger, and romantic relationship functioning. Sample 2 consisted of 60 romantic dyads. Females once again provided data on their gender harassment experiences and feelings of anger; their romantic partners reported on their own romantic relationship functioning. Full support emerged for hypothesized spillover effects: supervisor gender harassment indirectly and negatively influenced targets' romantic relationship adjustment and romantic relationship efficacy through target anger (Sample 1). Full support also emerged for hypothesized crossover effects: supervisor gender harassment indirectly and negatively influenced the romantic relationship adjustment and romantic relationship efficacy of targets' romantic partners through target anger (Sample 2). Implications for theory, research, and practice are considered. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

Adaptive capacity (AC)—the ability of a species to cope with or accommodate climate change—is a critical determinant of species vulnerability. Using information on species’ AC in conservation planning is key to ensuring successful outcomes. We identified connections between a list of species’ attributes (e.g., traits, population metrics, and behaviors) that were recently proposed for assessing species’ AC and management actions that may enhance AC for species at risk of extinction. Management actions were identified based on evidence from the literature, a review of actions used in other climate adaptation guidance, and our collective experience in diverse fields of global-change ecology and climate adaptation. Selected management actions support the general AC pathways of persist in place or shift in space, in response to contemporary climate change. Some actions, such as genetic manipulations, can be used to directly alter the ability of species to cope with climate change, whereas other actions can indirectly enhance AC by addressing ecological or anthropogenic constraints on the expression of a species’ innate abilities to adapt. Ours is the first synthesis of potential management actions directly linked to AC. Focusing on AC attributes helps improve understanding of how and why aspects of climate are affecting organisms, as well as the mechanisms by which management interventions affect a species’ AC and climate change vulnerability. Adaptive-capacity-informed climate adaptation is needed to build connections among the causes of vulnerability, AC, and proposed management actions that can facilitate AC and reduce vulnerability in support of evolving conservation paradigms. 相似文献
