摘　　要：日本海的形成与演化一直是研究边缘海问题的热点之一.日本海位于亚欧大陆东北缘,太平洋西岸,同时受到太平洋板块、欧亚板块、菲律宾海板块和鄂霍次克四个板块的相互作用,构造环境复杂.海域内的地形以弧后盆地为主,相间分布着海隆、沙洲、海底高原和裂谷等,是西北太平洋上独特的地质和地貌构造单元.因此,研究日本海有利于我们更好的理解西北太平洋弧后盆地的形成机理和海沟的俯冲机制.本文首先通过整理前人的研究成果和收集到的地质及地球物理学数据,对日本海的构造环境和地貌特征进行详细地描述.然后,分析现有研究成果在有关日本海的研究中仍存在的争议性问题并加以描述,包括日本海的形成时间、日本海的形成模式和日本岛弧演化等问题.接着,通过回顾前人提出的日本海的演化模式,我们发现日本海的形成与周围板块的俯冲作用密切相关,根据周围板块与欧亚大陆之间可能的相对运动,我们把日本海的演化模式分为四类:(1)仅受到太平洋板块的俯冲作用;(2)仅受到菲律宾海板块的俯冲作用;(3)同时受到太平洋板块和菲律宾海板块的俯冲作用;(4)形成初期仅受到太平洋板块的作用,随后受到太平洋板块和菲律宾海板块的协同作用.最后对日本海未来研究的发展方向进行展望.The opening and evolution of the Japan sea is one of the hot issues in Marginal sea research. Japan sea is located in the northeast of the Eurasian continent, and in the western Pacific Ocean, the tectonic environment is so complicated that it is surrounded by four plates： the Pacific plate,the Eurasian plate,the Philippine Sea plate and the Okhotsk plate. The main topography in the Japan Sea is back-arc basin, with ridges,banks, oceanic plateaus and rifts appear alternatively. All these make it one of the most unique geological and geomorphic tectonic units. So that＇s of great importance to research on the Japan Sea to get a better understanding of the forming mechanism of the back-arc basins in the western Pacific Ocean,as well as the mechanism of subduction of the trench. In this paper,we first describe the characteristics of tectonic environment,geology and topography of the Japan Sea in detail,based on the previous research results and geological and geophysical data we collected. Then by analyzing the results from previous research we list some debated controversies of researches that focus on the Japan Sea,such as the time of opening,the formation model of the Japan Sea,as well as the evolution process of the Japan arc and so on. After that,when arrange the collected researches of the evolution of the Japan Sea,we find that this evolution process is highly related to the subduction of the plates around,and we can classify different models into four kinds according to the possible relative motions between the Eurasia with the plates around during the formation of the Japan Sea： The Eurasia is（ 1） only subducted by the Pacific Plate;（ 2） only subducted by the Philippine Plate;（ 3） subducted by the Pacific Plate and the Philippine Plate, concurrently;（ 4） at the very beginning,subducted by the Pacific Plate,after a certain time,it is subducted by the Pacific Plate and the Philippine Plate,concurrently.Finally,we prospect the developing direction for future research on the Japan Sea.
