中文摘要：

在实验室条件下研究了裙带菜Undaria pinnatifida的不同孢子液浓度、附着基坡度和海水浊度对裙带菜孢子附着密度的影响。结果表明：裙带菜孢子附着密度随着孢子液浓度的增大而增加，呈正相关变化；随着附着基坡度的增大而减小，呈负相关变化；随着海水浊度的增加而减小，呈负相关变化。当孢子液浓度为3250～29250个／mL时，孢子液浓度（x1）与孢子附着密度（y1）的关系式为y1=724e^0.00008x1（R=0．978）；当附着基坡度为0～90°时，附着基坡度（x2）与孢子附着密度（y2）的关系式为y2=-0．7507x2＋97．447（R^2=0．9866）；当海水浊度为0．3～7．9时，海水浊度（x3）与孢子相对附着密度（y3）的关系式为y3=0．1354x3^3＋2．3802x3^2-18．557x3＋98．571（R^2=0．9896）。

英文摘要：

The influence of spore concentration, attachment gradient and turbidity of sea water on attachment density of spores in sea mustard Undaria pinnatifida was studied in laboratory. The results showed that the attachment density of the spores increased with the enhancement of the concentration with a positive correlation, but decreased by the enhancement of the gradient and the turbidity of sea water with a negative correlation. When the concentration of the spores ranged from 3 250 per mL to 29 250 per mL, the relationship between attached density（y1 ） and the concentration of spores（x1 ） was expressed as y1 = 724e^0. 00008x1 （R = 0. 978 ）. When the attachment gradient varied from 0° to 90°, the relationship between attachment density（y2） and attachment gradient （x2） was expressed as y2 = - 0. 7507x2 ＋ 97.447 （R^2 = 0. 9866）. When the sea water turbidity ranged from 0. 3 to 7.9, the relationship between attachment density（y3 ） and sea water turbidity （x3 ） was described as y3 = -0. 1354x1 ＋ 2. 3802x3^2 - 18. 557x3 ＋98. 571（R^2 =0. 9896）.
