Abstract
Summary
This report made up investigation to the individual amount , living beings amount , kind of the zooplankton each season from 2001 to 2004, and the estimation of total zooplankton , oar feet and wise water flea's amount of production, and analyse about the dependence among the zooplankton , environmental factor and biological factor, in order to promote the knowledge of this sea area ecological environment.
The total zooplankton's individual amount lies between 12,165,176,400ind./1000m3, examine average content that stand each, in order to is it stand 8 with is it stand 4 most high to examine to examine. Individual amount's change in four seasons is the highest with summer, it is the minimum content in winter to take second place in spring and autumn. The average individual amount of 2004 is the tallest, took second place in 2001 and 2002, 2003 was for being lowest. Main classification average individual amount respect is with oar foot, tail worm and mao content of jaw type relatively high, and is obviously higher than two seasons of autumn and winter with the content of zooplankton of two seasons in spring and summer. Spring , summer , autumn and winter all rely mainly on oar feet and tail worms. Zooplankton's living beings amount lie between 2.2923.95g/1000m3, the difference among season is obvious. Investigate that the universe of 11 pieces of classification zooplankton of sea area is divided into wet and heavy (X ) relational expression four seasons heavily (Y ): Spring Y =0.116X-0.121 , summer Y =0.119X +0.043 , autumn Y =0.118X +0.037 and winter Y =0.106X+0.031.
Total average second amount of production (mgC/m3/day ) of zooplankton lies between 0.02.84 during the investigation of sea area of small house of salt, it is 0.31 on average , among them oar feet lie between 0.01.70, 0.21 on average, accounting for total 61.7% of second amount of production of zooplankton, it is 0.18 on average that the wise water flea lies between 0.01.67, accounts for foot 85.7% of second amount of production of oar, accounts for 58.0% of second amount of production of zooplankton . Count and make with elementary productivity the analysis of coefficient correlation of second amount of production and the temperature , phytoplankton cell. It is 0.89 of the temperatures to be the highest, it is the elementary amount of production- 0.26 to be the lowest. Main composition is it hive off nine classification to analyse, first temperature, wise water flea, maos of jaw type and total zooplankton, the second group is tail worms and sword water flea, the third group, for young growing type , phytoplankton and jellyfish, show one hundred points of more close kinds of the classification in the zooplankton's clustering of sea area of small house of salt, perhaps the change of individual quantity is related. Basis season for four year, 8 pieces of main classification percentage of zooplankton, carry on cluster's analysis (CA ). In spring , show that the wise water flea's percentage (57.46% for 29.80% springs ) is higher for more independent classification , the change situation is relatively great. In summer , autumn and winter, the change in the period of eight pieces of classification percentage (0.001.23% ) is relatively great, it is more difficult to find out the dependence of the change. Salt small house the sea area the zooplankton the getting higher most,but belong to there aren't water flea and the tail worms not wise of classification not main , the result shows zooplankton's high content to summer, does not totally come from the wise water flea and contribution of tail worms, but the mutual contribution via most other classifications .
