The pattern of lunar cycle can be classified into three strategies:(1) Planulation of S. hystrix and P. damicornis showed clear lunar periodicity and the peak of larval release shifted with different months. The peak of planulation occurred around the full moon in winter then shifted gradually to the first quarter moon phase in summer. The phase shift of larval release may be related to the seasonal variation of seawater temperature and the sudden temperature drops caused by upwelling.(2) Planulation of S. pistillata showed clear lunar periodicity and the peak of larval release occurred around the full moon.

The results show that a the variation of annual mean runoff of Huayuankou section exist an intrinsic dynamic mechanism, which is the results of joint action of affecting factor of periodicity and non-periodicity, having obvious chaos characteristic; b the correlation dimension of attractor of phase space is 5.09 and saturation inserted dimension is 14. It shows that to establish a mathematical model of the annual mean runoff system of Huayuankou at least requires 6 independent variables and the required saturation inserted dimension for rebuilding phase space is 14; c the steady estimate of Kolmogorov entropy is 0.14, showing the average predictable time of the annual mean runoff variation of Huayuankou is about 7 years and; d using nonlinear deterministic chaos model is more suitable to describe the variation of annual mean runoff of Huayuankou.
