The evolution and sustainable development of marine ecosystem has become a hotspot of marine research. We analyzes the characteristics of dissipative structure of marine ecosystem from the perspective of human-sea complex ecosystem. Based on the theory and method of dissipative structure and information entropy, we construct the index system of marine ecosystem evolution from entropy flow and entropy generation, and took the coastal province of Shandong as an example to analyze the evolution trend of marine ecosystem with entropy change. Adopting sustainable development evaluation model, we explored the sustainable development ability of marine ecosystem from an integrated and coordinated perspective. The results showed that:(1) from 2006 to 2013, the internal negative feedback mechanism of marine ecosystem had always been dominant in Shandong Province, the system was developing in the direction of orderly, the internal vitality of the system increased after 2009, and the health and stability of the system became stronger; (2) the carrying capacity, the value output capacity and the comprehensive environmental management capacity of the marine ecosystem in Shandong Province were constantly increasing, and the comprehensive sustainable development capacity was on the rise; (3) the comprehensive development level of marine ecosystem in Shandong Province had been improved, and in 2013, it entered a higher development stage; the overall coordinated development capability between marine social economy and natural ecosystem was in the period of fluctuation increase.
