中文摘要：

于2006年冬至2007年秋分四个季度对海南万宁小海近岸表层海水的弧菌种类分布及数量变化进行了调查。共分离到27种弧菌属细菌,其中副溶血弧菌、创伤弧菌、溶藻弧菌、霍乱弧菌、河流弧菌和拟态弧菌6种弧菌为主要弧菌。在6种主要弧菌中,溶藻弧菌、副溶血弧菌和霍乱弧菌在夏季和秋季检出率较高;河流弧菌在春季和夏季的检出率较高;拟态弧菌在冬季的检出率较高;创伤弧菌在全年不同季节检出率相当。海水中弧菌的数量分布为气候较为温和的春、秋季较高,而温度较高和较低的夏、冬季则较低。相关性分析显示,弧菌数量分布与盐度和酸碱度呈显著正相关;弧菌种类分布与温度、盐度、溶解氧和酸碱度的相关性则因弧菌种类和季节不同而异。聚类分析结果表明,该海域夏季和秋季弧菌组成的相似性最高;距离较近的站位间弧菌组成相似性通常较高。

英文摘要：

The species and numbers of Vibrio bacteria and some environmental factors were investiged from winter of 2006 to autumn of 2007 for the inshore surface water of Xiaohai,Wanning City,Hainan Province.The results of Vibrio species survey showed that,totally 27 Vibrio species were isolated from the inshore surface water of Xiaohai and the main Vibrio species isolated from Xiaohai including V.parahaemolyticus,V.vulnificus,V.alginolyticus,V.Cholerae,V.fluvialis and V.mimicus.V.alginolyticus,V.parahaemolyticus and V.cholerae were the dominant species in summer and autumn;V.fluvialis was the dominant species in spring and summer;V.harveyi and V.mimicus were the dominant species in winter;V.vulnificus could be detected in all seasons and its numbers were constant in differdent season.The total numbers of Vibrio were higher in spring and autumn,lower in summer and winter.Correlation analysis showed that,the correlation between the number of Vibrio distribution and salinity,pH were notable,the correlation between Vibrio distribution and temperature,salinity,dissolved oxygen and pH were different among different Vibrio species,different sampling stations and different seasons.The results of cluster analysis showed that,the composition of Vibrio species had high similarity in summer and autumn and at the stations with shorter distance.
