제주도 주변해역에 출현하는 중국대륙연안수의 특성을 여러자료를 근거로 분석한 결과를 요약하면 다음과 같다. 1. 제주도 주변해역에 출현하는 여러 수괴중 $32.20\%0$ 이하의 저염분수는 중국대륙연안수로 해석된다. 2. 본 연구기간중, 제주해협 표층에는 1월${\sim}5$월 중순까지는 $34.00\%0$ 이상의 고염분수가 출현했고, 5월 하순부터 점차적으로 염분이 저하하여 $32.20\%0$이하의 중국대륙연안수는 7월초에 출현하여 10월중에 소멸했다. 3. 제주해협에서 중국대륙연안수의 두에는 평균 25m이고, 대체로 50m 정도의 깊이까지 영향을 주고 있다. 그러므로 동 해협의 하계 성층구조는 $0{\sim}50m$까지는 심한 염분약층이 형성되며 50m 이심은 동계와 같이 균질염분층에 가까운 성층이 된다. 4. 하계에는 제주도 주변표층 대부분의 해역에 중국대륙연안수가 출현하지만 그 중 최저염분을 갖는 이 연안수의 Core는 제주도 서방해역에서 제주해협 서쪽 입구로 유입되어 동 해협 중앙부를 통해 해협 동쪽으로 유출되며, 해협을 통과한 후에는 과유의 형태로 이동되는 것 같다.

China Coastal Water(CCW) appeared in the neighbouring seas of Cheju Island has been analyzed and the results are as follows: The water with salinity below $32.20\%0$ in the neighbouring seas of Cheju Island in summer is thought CCW. During the period from April 1985 to August 1986, salinity of more than $34.00\%0$ was appeared in the Cheju Strait during January to mid May, but it decreased gradually from late May. CCW with salinity below $32.20\%0$ appeared in the Cheju Strait in early July and disappeared in October. The mean thickness of CCW in the Cheju Strait was about 25m and CCW had an influence of up to about 50m depth. And stratification structure of the Cheju Strait in summer was halocline between the surface and 50m depth and homogeneous salinity layer below 50m depth. It seems that although CCW appears in the wide area of neighbouring seas surface of Cheju Island in summer, the core of this CCW which has the lowest salinity flows into the Cheju Strait from the western seas of Cheju Island. This CCW flows out the east through the central part of the Cheju Strait and then seems to be transported further in the form of eddy.
