The zooplankton identified belongs to 19 species, and its biomass ranged from 3.75mg/L to 7.74mg/L, averaging 5.93mg/L. The diversity index of the zooplankton was relatively low too. In the cultured rice fields, the phytoplankton identified belonging 53 gena, 6 phyla.

For example, we use geometric distribution to describe the life distribution of runs of a species in transect surveys of plant populations and inventory demand distributions. In the theory of reliability, geometric distribution is one of the most important discrete probability distributions because of its loss of memory.
在可靠性理论中,由于几何分布的无记忆性,使得其是离散型寿命分布中最为重要的寿命分布之一,其相当于指数分布在连续型寿命分布中的地位,这正如程侃研究员在文献[5]中所指出的"在离散寿命的情形,几何分布起着连续情形下指数分布所起的作用"一样。

Ecological analysis of morphological and genetic variation revealed that:(1) The averages of morphological characters were significantly negatively correlated with WSF (2) Dominant frequencies of some RAPD loci were significantly correlated with WSF (3) The correlation between morphological variation and genetic variation was not significant (4) The cluster analysis based on morphological and genetic evidence supported that all population can be divided into three ecotypes: saltmarsh reed, freshwater reed and giant reed.
