| 摘 要： | 研究了1998年5月，10月，12月。1999年8月以及2001年7月和9月的太湖梅梁湾的初级生产力和光照时发现，在不同水层中，20cm左右的水深处初级生产力最大，最大初级生产力与叶绿素a的关系是Pm=0.012Chla]-0.028Chla](n=30），在叶绿素a与光谱之间关系以及初级生产力与光强之间关系的基础上，建立了初级生产力与光谱之间的关系，在蓝光光谱波段和红光光谱波段的Kd较大，较大，而550nm的Kd最小。

| Abstract: | According to the study of the pimary production and light in Meiliang Bay Taihu Lake in May, October, December of 1998, August of 1999 and July, September of 2001, the anthors found that the greatest primary production was at the depth of 0. 2cm, the relationship between primary production(P) and the concentration of Chla was; P = 0. 012-0. 028 Chla] (n= 30). On the basis of the relationship between light spectrum and concentration of Chla, as well as the relationship between primary production and light intensity, the relationship between primary production and light spectrum was found and validated. Further analysis revealed that the Kd of light spectrum at the blue end and at the red end was greater than that of green, the lowest was at 550 nm. |
