生态交错带理论及其在海洋生态学中的应用

在介绍生态交错带理论的基础上，提出开展海洋生态交错带研究。海洋生态交错带定义为相邻海洋生态系统之间的过渡区。海洋生态交错带主要研究内容包括：①建立海洋生态交错带的划分标准；②生态交错带的三维结构；③生态交错带的生态功能；④海洋生态交错带对全球变化的敏感成分和响应机制；⑤海洋生态交错带的生物多样性维持机制；⑥海洋生态交错带与渔场形成的关系。讨论了海洋生态交错带与陆地生态交错带和海洋锋面的不同之处，指出海洋生态交错带研究极有希望成为海洋生态学新的生长点。

ECOTONE THEORY AND ITS APPLICATION TO MARINE ECOLOGY

The transition region between the neighboring ecosystems was called ecotone. In view of global ecology and landscape ecology, ecotone may be divided into four kinds: terrestrial ecotone, inland water-land ecotone, marine-land ecotone and marine ecotone. The marine ecotone was presented and defined as the transition region between the neighboring marine ecosystems according to the ecotone theory. The main research fields are as following:to build the criteria of marine ecotone, such as biodiversity index or other ecological indexes, three dimensional structures of marine ecotone,  the ecological function of marine ecotone, the sensitive elements and responsive mechanics of marine ecotone to global change,the maintaining biodiversity mechanics in marine ecotone, the relationship between marine ecotone and form of fishery field. The difference between marine ecotone and terrest rial ecotone and marine front were discussed. The marine ecotone field will become one new “growth point”in marine ecology.
