Study on the Scientific and Legal Basis of Ecological Damage Compensation [PDF]
, 2014 生态补偿是协调经济发展与环境保护的有效经济手段,在中国得到了广泛重视。由于受到学科范畴的限制,学术界和管理界对生态补偿的内涵、经济性质和法律性质还存在许多争论,关于生态损害的科学含义及与之对应的补偿与赔偿的法理基础尚有待完善。本文旨在梳理生态补偿的相关术语,探讨生态损害及损害补偿与赔偿的科学含义、法理差异及法律制度,从而为我国进一步开展生态补偿的理论研究和实践提供参考。论文首先从环境管理、环境经济学以及法学三层面对生态补偿的内涵进行分析,并在探究生态补偿实践的演变历程的基础上 ...

Research and the Protection for the Population of Chinese Horseshoe Grabs in Xiamen [PDF]
, 2009 中国鲎是珍贵的海洋活化石,有着极高的医学价值和科研价值。厦门海域曾分布大量的中国鲎,而近年来,由于危及鲎生长繁殖的围海造地、滩涂养殖以及狂捕滥杀现象层出不穷,再加上海水水质和沉积物环境的恶化,使得厦门海域中国鲎资源急剧下降,甚至已经难觅其踪。文章从中国鲎的栖息地破坏、环境污染以及过度捕杀三个角度,分析人类活动对中国鲎种群的威胁,并提出划定厦门中国鲎自然保护区,加强宣传教育和科学研究等保护厦门海域中国鲎资源的几点设想。As a kind of rare oceanic "living fossil ...
