Studies on the bottom fauna and biomass in Nishina Sanko;

By means of simulating the regressions of biomass, volume, leaf- area of each organs of the forests,allometric rules of the five main forest communities at the Hueditang forest region were quantitavely studied, The average standing crop, average stocked volume,average produc-tion, average volume increment and the standing crop of dead ground - stratum of the forests were 133- 42t/hm2, 166.

According to the annual variations (May 1990 - April 1991) of species composition , standing crop and productions of phytoplankton in Houhu Lake, Wuhan, it is found that the dominant taxa are no other than Chloropgyta, Bacillatiophyta and Cyanophyta in the lake with their standing crop and production being highest in autumn and lowest in spring.

According to the investigation on zoobenthos of Donghu Lake in 2003, this paper deals with calculating whole zoobenthic standing crop, and analyzing the standing crop of 6 dominant species and their distributive patterns, and evaluating environmental quality using bio-index.

It was shown in the study that the standing crops of the as-similative system(AS)and the unassimilative system(UAS)in the community were concentrated mainlywithin 0～20 cm and 0～30 cm,respectively,from the ground level.

The community structure of copepods, including species composition, standing crops dynamics and diversities, was studied in a oligo mesotrophic, large, deep water lake - Qiandao Lake, Zhejiang.

This article is mainly about the investigation results on the extand quantity and distribution of Benthonic Animal resources in the Hasuhai Lake.
