Production and realization of marine ecosystem services
海洋生态系统服务的产生与实现

Based upon expatiation of the connotation of marine ecosystem services, we analyze the production processes and realization approaches of marine ecosystem services. We attempt to link major components and (or) functions of marine ecosystem to their related services. The physiological and ecological processes from each components and (or) functions to their related services are also presented. The results we obtained show that there are 2 sets of production processes. Some services are directly produced from the biological components and (or) system. The others are produced by system functions. The physiological and ecological processes do not produce services directly. The realization of marine ecosystem services contains 2 approaches. One approach is marine ecosystem; the other is marine ecological- economic system.
