In order to study the ecotourism of small benthic animals in the southern Yellow Sea anchovy spawning grounds, this article uses sediment samples obtained from 10 sites in the southern yellow sea anchovy spawning grounds in June 2018 to determine the abundance and abundance of small benthic animals. Related researches on biomass and environmental factors have provided environmental evaluation indicators for the study of microbenthic ecotourism in anchovy spawning grounds in the South Yellow Sea. The survey results show that the average abundance of small and medium-sized benthic organisms at different depths in the South Yellow Sea sediments, such as the surface (0-2cm), the deeper layer (2-5cm) and the deepest layer (5-8cm), is 890.8ind.10cm- 2. The average biomass is 1220µg.10cm-2; 10 environmental factors in the sediments, such as the depth of water, the temperature of the bottom water of the sediment, the amount of organic matter, the amount of chlorophyll, the amount of pheophorbide, and the water content, Ch-a, the amount of sand, clay (%) and the median particle size and other parameters show a correlation, among them, the abundance is negatively correlated with water depth (r=-0.579, P<0.05), and Ch- a is positively correlated (r=0.497, P<0.05), abundance and biomass are negatively correlated with bottom surface water temperature and clay content (r=-0.357, P<0.05); a total of 17 species of small benthic animals at different depths have been identified Among them, marine nematodes (74%), copepods (14%), and polychaetes (7%) are the most important populations in terms of numbers; in comparison with other sea areas, the South Yellow Sea anchovy spawning ground The groups and numbers of meiobenthos are very close to those of other sea areas; in terms of vertical distribution, meiobenthos gradually decrease at the surface, sub-surface, and deep layers of sediments, and different species are distributed in depth. There is a significant difference on the above. This paper studies and analyzes the biocommunity composition and biodiversity characteristics of the microbenthos in the anchovy spawning grounds in the South Yellow Sea, which can be used to protect the microbenthos in the anchovy spawning grounds for ecotourism and real-time detection of the marine environment in the South Yellow Sea. Contributed to the theoretical foundation.
