Behaviour ecology, physio-ecology and community ecology of vines in the evergreen broad-leaved forest of Tiantong National Forest Park, Zhejiang Province, China, were studied and rich first-hand data were collected in this project.Some vines with different climbing motheds were much different in leaf anatomy, ecophysiology, growth rhythm and behavior, and another vines with same climbing methods showed similar adaptation to habitat, on which their distribution in a forest depended. The concept of climbing unit consisted of internode, leaves and tendrils or other climbing organs on it was put forth, and the method to calculate and value the climbing capaity of a vine was set up. In the meantime,experimental ecology of a twining vine Humulus scandens was carried out.

The main reasons caused theses problems are as follows: beyond marine carrying capacity and environment capability by predatory and extensive manners, over-exploitation of bioresources resulted in the disturbance of marine ecosystem and the obstruction of matter and energy circulation. Marine environment pollution and unreasonable oceanographic engineering caused serious damage of marine entironments, weakness of marine eco-functions, and degradation of marine ecosystems. The population explosion as well as the trend of population towards coast inflicted tremendous pressure on marine resources and environment. The weakness of marine laws system and the infirmness of macroscopical control by government policies relulted in unreasonable utilization, inefficient management, and insufficient protection of marine bioresources.

其主要原因是:对海洋生物资源的掠夺性、粗放性开发,造成资源过度利用,超出海洋承载力及其环境容量,物质能量循环出现障碍,海洋生态系统失衡;海洋环境污染和不合理的海洋开发工程,造成生境破坏,生态功能减弱,生态系统退化;人口增长和趋海发展,给沿海资源环境造成巨大压力;涉海法律法规体系薄弱,国家宏观政策调控不力,未能合理利用和有效管理、保护海洋生物资源和海洋环境。
