三国水军与水战述略

三国时期，魏、蜀、吴都有水军建置，水战在三国之间时有发生。曹魏虽为统一南方而始终致力于水军发展，但限于地域、造船技术等原因，水军发展缓慢，水军作战能力不强。蜀汉曾在荆州建置有一定力量的水军，但在荆州失守之后，水军数量锐减，水军作战能力严重削弱。孙吴以水军立国，水军力量在三国中最为强大，其水军的发展大致经历了崛起、鼎盛、衰落三个阶段。

The Water - forces(Navy) and Water - battles in the Period of the Three Kingdoms

During the era of the Three Kingdoms,the Wei,Shu,Wu States all set up water-forces,and water-battles often occurred among the three kingdoms.In order to unify the southern areas,the Wei State committed itself to develop water-forces all the time,but saw very slow progress owing to its geographic conditions and skills of shipbuilding.The Shu State once had a bit strong water-forces,but after Jingzhou was lost,the capacity of the water-forces was rapidly reduced and severely weakened.The Wu State were founded with the help of its water-forces,so the power of its water-forces was the strongest one among the three states,the development of which was marked with three phrases as follows:rise, reach its best and decline.
