Q wave Shengsi Islands with 3 types of biological communities, that low-salt, wide and high salt, salt, ¨ all types of communities communities, algae, polychaetes, molluscs and crustaceans in the density and biomass in different sections different distribution of the different tidal zones, such a number of differences,[link widoczny dla zalogowanych], resulting in community similarity and structural differences. Figure 1 is the structure of benthic communities in the quantitative analysis.

Looking at the results from the numerical analysis (Fig. l, Table 1), nearly off the community (SJ2) for the coastal communities (DY1) and offshore communities (H, SS4) had between the types of assistance. This result proved the correctness of the results of previous studies _5j. 3.2.2 Cluster analysis using Bray-Curtis community similarity coefficient community cluster analysis, the results shown in Figure 2. Figure 2 shows the value at 5O draw a line, 4 communities can be grouped into two categories. From the numerical analysis can be seen: for the coastal community off the coast of the transition to community,[link widoczny dla zalogowanych], which further proved the correctness of the results of the previous 【5j. Figures 1 and 2, consistent results. Currently, Whif. taker and Fairbanks and the Bray-Curtis of the two indicators have been widely used for community similarity and cluster priced. 2 Kids in crucian carp 9,010,[link widoczny dla zalogowanych],096 3,040,506,070 base shelf ROCKY pounds during the action with the benthic community analysis diagram tunicates Fig. 2Clusteranalysis ... fb ~ thJeinv ~ tebrateeOl ~ tftu-nityofrockyintertidalz0tlealongShengsiarch/pehSo analysis of ['.
