[ Method] With Porphyra yezoensis as tested materials , the general stations of P. yezoensis i nJiangsu province in 2003 were investigated . Based onthe meteo- rological data from8 stations of Jiangsu coast , the cli matic suitability of laver culture in Jiangsu province was analyzed . [ Result ] The culture area of P. 2 yezoensis in Jiangsu province in 2003 reached 9 640 hm and the production value exceeded one billion yuan . The culture area , yield and production value of laver in Nantong region were all highest , followed by Lianyungang and Yancheng . The shoal of Dongsha Island in Yancheng had greater development potential . Th
