, 2013 基于中国的农业社会背景,竺可桢对人口与水土保持、资源和环境等问题进行的深入思考,既与西方的可持续发展思想相契合,也与当前"生态文明"建设具有诸多共通之处。本文重点从竺可桢关于人口与水土保持、资源的可持续利用和环境保护问题等方面的思考展开分析 ...

Wildlife Letters, EarlyView.Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

全球能源互联网工业企业从电能消费者转变为产消者的环境生态可持续性仍是个未知数。以水泥产消者为例，基于能值分析方法，提出了光伏发电有效能值可持续发展指数，对分布式光伏发电系统在生命周期内投入的成本和“免费”资源进行统计和综合计算；接着，提出了基于能值指标的绿证与碳抵消电量折算方法，对不同用电模式产生的碳减排效果和电-碳-绿证融合的自然价值进行量化和比较。结果证明，水泥产消者的分布式光伏系统单位功率输出的能值需求低；“自发自用”模式可兼容经济性实现高效减碳；能值指标减小了月度绿证和碳市场的可交易量。据此 ...

Wildlife Letters, EarlyView.We staged dyadic interaction trials between two kangaroo rat species threatened by habitat loss to test whether one species dominates in direct interactions in the field. We found that Stephens’ kangaroo rat (Dipodomys stephensi) residents and intruders were dominant over Dulzura kangaroo rat (Dipodomys simulans). These results suggest that D. simulans

When and why to give shorebirds a head start
Conservation Biology, EarlyView.Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

, 2014 可持续发展是我们时代的主题,也是人类面临的最大挑战.自20世纪70年代,尤其是近20年来,可持续发展的概念日益频繁地出现在学术文章、政府文件以及公益宣传和商业广告之中.然而,为可持续发展提供理论基础和实践指导的科学——可持续性科学——是在21世纪初才开始形成的.该科学在短短的十几年中迅速开拓、不断发展,正在形成其科学概念框架和研究体系.中国是世界大国,是可持续性科学的哲学思想——"天人合一"——的故乡,有必要承担起时代之重任,在追求"中国梦"的同时促进全球可持续发展 ...
