摘　　要：收集了宁德沿海2011年9月-2012年8月1周年的风和波浪连续观测资料,并对该海域的风和波浪特征进行了统计分析。该海域观测期间内全年平均风速年均为7.2m/s,平均有效波高为1.04m。常风向为NNE向,强风向为NE向。常浪向为E向,强浪向为E向。根据风和波浪场数据对宁德沿海的风能和波浪能进行评估,评估结果发现宁德沿海的风能和波浪能蕴藏量较丰富,年平均风能密度能达到411W/m^2,平均波浪能密度能达到2.6kW/m。对研究海域重现期波浪极值进行了推算,受东侧四礵列岛阻挡,宁德沿海南部海域主要受SE向波浪影响,北部海域主要受E向波浪影响。若对宁德沿海进行新能源开发,可以进行风能和波浪能的联合开发利用。Wind and wave measurement data are used from September 2011 to August 2012 in Ningde coastal area. The characteristics of wind and wave energy resources are studied base on the observed da- ta. The results of the energy assessment showed that this area possesses huge wind and wave energy potentialities. Annual average wind energy density reaches up to 411W/m^2 and wave power density reaches up to 2. 6 kW/m. The extreme wave parameters are calculated by SWAN model. The results showed the southern sea areas is mainly affected by waves from SE direction, while the north sea area is mainly affected by the waves from E direction. The combined exploiting of wind energy and wave energy is suggested.
