通过潜水调查枸杞岛铜藻的分布特征,并统计西北太平洋近65年台风生成的波浪对枸杞岛产生的影响以及近3年枸杞岛日常风力和风向的变化规律,分析了枸杞岛铜藻分布格局与风浪影响之间的关系。结果表明:铜藻主要分布在枸杞岛西北侧沿岸,且集中分布在平均海平面以下1~4 m较浅的水深范围内,而枸杞岛东到南侧则无铜藻分布,这与85.1%台风生成的波浪影响枸杞岛的东到南侧有关;近年来枸杞岛铜藻数量减少,但近年来台风生成的波浪对枸杞岛产生的影响并没有显著增强,说明铜藻数量的减少并不是由于近年来台风的显著增强而引起;虽然枸杞岛日常风力以西北-北向最强,西北-北向风向的发生频次也较多,但铜藻却集中分布在枸杞岛西北侧沿岸,说明枸杞岛西北侧大面积贻贝养殖筏可能对风浪的影响起到一定缓解作用,保护了近岸岩礁区铜藻的分布与生长。因此,在铜藻垂直分布上移的趋势下,风浪的影响加剧了对铜藻的破坏作用,风浪对枸杞岛铜藻的分布格局起到重要作用。
The distribution characteristics of Lycium barbarum in the wolfberry Island were investigated by diving, and the influence of the waves generated by the typhoon in the western North Pacific nearly 65 years on the wolfberry island and the daily wind and wind direction of the wolfberry Island in the past three years were analyzed. Relationship with the impact of storms. The results showed that the distribution of copper algae was mainly along the northwestern coast of Goji Island and concentrated within a shallow water depth of 1 ~ 4 m below the mean sea level. However, there was no distribution of copper and algae from the east to the south of Goji Island, which was consistent with 85.1% The waves generated by the typhoon are related to the east of the wolfberry island to the south. In recent years, the quantity of copper algae in the wolfberry Island has decreased. However, the waves generated by the typhoon have not significantly increased the wolfberry island in recent years, indicating that the decrease in the number of copper algae is not due to Although the daily wind of Goji Island is the most northerly-northerly and northwest-northerly, the occurrence of typhoon is more frequent in recent years, but the distribution of copper algae is concentrated along the northwestern side of Goji Island, indicating that the northwest side of Goji Island Large-scale mussel breeding rafts may play a role in mitigating the effects of wind and waves and protect the distribution and growth of copper algae in the coastal reefs. Therefore, under the tendency of the vertical distribution of copper algae moving upward, the influence of storms aggravated the destructive effect on the copper algae. The storms played an important role in the distribution pattern of copper alga in Lycium barbarum.
