宁夏六盘山自然保护区环颈雉秋季栖息地的选择

open access: yes野生动物学报, 2009
2007年和2008年9~10月,在宁夏六盘山国家级自然保护区采用样带法对环颈雉的栖息地选择进行了研究。共测定了31条样带上的91个环颈雉栖息地利用样方和100个任意样方的12个生态因子。结果表明环颈雉偏好利用草原和草甸,避免选择其他4种植被类型;偏好利用无树的生境,随机利用以桦和椴为优势乔木的生境,避免其他4种优势乔木的生境;偏好位于阳坡的生境,随机利用半阳坡和半阴坡的生境,避免利用阴坡的生境;偏好选择下坡位的生境,随机选择中坡位的生境,避免选择上坡位的生境。对利用样方和任意样方进行Mann ...

Measuring the Value of Blue Carbon in China Coastal Zone [PDF]

open access: yes, 2017
自工业化以来,大气二氧化碳及其他温室气体的浓度已增加了40%,不断增 加的温室气体排放是全球气候变化的重要原因,从而对全球粮食生产以及人类的 生活和生计造成严重影响,气候变化是人类21世纪面临的重大挑战之一。研究 显示全球自然系统封存的生物碳中,超过一半是由海洋生态系统所捕获,被海洋 生态系统捕获并封存的碳称为蓝碳。维持和促进海洋生态系统封存二氧化碳的能 力是应对气候变化的关键措施之一,但是海洋生态系统在应对气候变化中的作用 被长期忽略,其中重要的原因之一是没有赋予蓝碳适宜的价值。本文在对蓝碳理 ...
