摘　　要：[目的]为提高紫菜养殖中减灾与防灾能力提供科学依据。[方法]以条斑紫菜为试材,调查江苏省2003年条斑紫菜的养殖概况,利用江苏沿海8个站点的气象资料分析江苏紫菜养殖的气候适宜性。[结果]2003年江苏省条斑紫菜的养殖面积达9640 hm2,产值超过10亿元。南通地区紫菜养殖面积、产量和产值均最高,其次为连云港和盐城。盐城东沙的沙洲具较大发展潜力。南通地区气候最适宜紫菜养殖,连云港次之,盐城最差。如东到启东沿海,尤其吕泗附近对于紫菜养殖最为理想。造成区域间养殖紫菜气候适宜性差异的主要是大风、冻害、雾害、寡照等灾害性天气指标,而温度等常规指标区域间适宜性差异较小。[结论]加强气象条件等级预报,可为紫菜病害的防治提供参考。The research aimed to provide the scientific basis for enhancing the abilities of disaster pievenfion and reduction in laver cultme. [Method] With Porphyra yezoensis as tested materials, the general stations of P. yezoensis in Jiangsu province in 2003 weie investigated. Based on the meteorological data from 8 stations of Jiangsu coast, the climatic suitability of laver culture in Jiangsu province was analyzed. [ Result ] Tne culture area of P. yezoensis in Jiangsu province in 2003 reached 9 640 hm^2 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 hanyurgang and Yancheng. Tee shoal of Dongsha Ishnd in Yancheng had greater develotment potential. The climate of Nantong region was most suitable for laver culture, followed by Lianyungang, and that of Yancheng was worst. Tee coastal area from Rudong to Qidong, especially for around Lvsi was most ideal for laver culture. The regional differences of climatic suitability for culturing laver were mainly caused by such disaster weather indexes as gale, freezing injury, fog damage and scant light, while that caused by conventional indexes such as tenoerature was stroller. [ Conclusion] Strengthening the prediction of meteorologic conditions grade could provide references for preventing the diseases of hver.
