【摘要】 基于2008～2010年浒苔发生的事实,着重分析研究了日照时数和降水量对浒苔生消的影响。分析表明,5月上旬浒苔生成时,其发生地附近江苏近岸平均日照时数85.2h,比常年偏多14.7h;6月下旬浒苔覆盖青岛海域的面积一般在400～800km2,影响较明显,此时青岛平均日照时数74.3小时,比常年偏多8.2小时,表明日照充足,光合作用加强,适合浒苔生长繁殖。5月中旬江苏近岸降水量39.6mm,比常年偏多13.7mm,加快了浒苔生长发育;青岛近海浒苔大面积发生时,降水量是由5月中旬29.8mm转为6月下旬8.7mm(光照充足),再到7月上旬63.0mm,从偏多到偏少再到偏多交替出现的。降水偏多促进了浒苔大发生。更多还原

【Abstract】 Based on the observation of entermorpha prolifera from 2008 to 2010, the effects of sunshine duration and precipitation on the bloom and extinction of enteromorpha prolifera was analyzed emphatically. Analysis showed that average sunshine hours of 85.2 hours in early May along the coastal area of Jiangsu, which was 14.7 hours more than normal years. Entermorpha prolifera covering 400-800 square in Qingdao coastal waters in late June, and average sunshine of 74.3 hours in Qingdao, which was8.2 hours more than normal years. Sufficient sunshine was suitable for the growth of entermorpha prolifera. Precipitation of 39.6mm along the coastal area of Jiangsu in mid-May, and 13.7mm more than normal years, which was conducive to the growth of entermorpha prolifera. When the entermorpha prolifera outbreaked in the off-shore area of Qingdao, precipitation of 29.8mm in mid-May, and 8.7mm in late June, then 63.0mm in early July, which from more to less then to more alternated. The plentiful rainfall was beneficial to the outbreak of entermorpha prolifera更多还原
