Beijing small lake community structure of benthic invertebrates and nutritional status of

When algae die, their, to clarify the lake tide, the water quality differences between one another is not obvious. F5 spring months), the chironomid larvae species number was significantly reduced, so here mainly to the lake g compared and discussed the information in January. The results show that in September the average diversity index of the wave () values were: P Lake,[link widoczny dla zalogowanych], 1.60, F Lake, 2.40, N Lake, 1.2lJC tide, 1.10, S surges,[link widoczny dla zalogowanych], 1.01 Lake not sampled). According to Huang Yuyao et al (1982) on the relationship between value and quality standards to judge, in addition to light pollution the lake F, the remaining patients were classified as moderately polluted bodies, but the degree is slightly different, that is, heavier after the three lakes some. Technical quality of reference data \6 small lake that Beijing first three lakes are mesotrophic lakes, the latter three are in a eutrophic lake water. 5 Conclusion of small lakes before the Beijing six lakes are molluscs 3 Chironomidae larvae of a type of a few hair, which is equivalent in nutritional Lakes | Lake after three chironomid larvae are a few hair types, the equivalent of a eutrophic lake. S ~ nnon diversity index value and the results are basically kiss sets. Benthic indicator species, dominant species, density and community structure are valuable biological indicators of shallow lakes. Which Bellamya and crude abdominal chironomid Beijing 6 small as indicators of biological water quality of the environment, the former indicates better water quality, which indicates poor water quality.
