Marine Ecological Damage Assessment and Compensation: Theory, Approaches and Case Studies [PDF]

open access: yes, 2015
海洋生态系统是地球生命支持系统之一,也是支撑人类生存和发展的重要资源宝库,对于人类经济的繁荣和生活质量的提高贡献巨大。然而,随着人类对海洋开发进程的加快,海洋环境与海洋生态系统面临着越来越大的压力,海洋资源利用冲突、海洋环境质量退化和生态破坏问题日益凸显。建立海洋生态损害补偿机制被认为是解决海洋资源利用冲突,保护海洋环境和生态系统永续发展的有效途径之一,而海洋生态损害补偿理论和方法的研究则是其重要的前提。目前,生态补偿的研究与实践多集中在陆域生态系统,涉海方面的研究尚不多见 ...

森林涵养水源的价值核算研究

open access: yesShuitu Baochi Xuebao, 2003
森林涵养蓄水价值量核算方法较多,包括土壤蓄水估算法、水量平衡核算法、多因子回归法和用地下径流增长法计算森林涵养水源的价值。但此方法存在一个问题,需要分别求出森林涵养水源的价值,然后进行合成。在合成过程中,可能存在信息叠加等问题,使计算结果偏离实际,为此提出了森林涵养水源价值量核算模糊数学模型,V=(A○R).S,A为要素评价的权重值,R为影响森林涵养水源单要素评判矩阵所组成的综合评价矩阵,S为水资源价格向量,S=(P,P1,P2,P3,0)。

We then analysed these detections at two different spatial scales to assess the habitat associations and diel activity of this species. We found that the sun bear is tolerant to moderate habitat disturbances. ABSTRACT Degraded tropical forests,
