摘要：

Number of polychaete species identified from Vellar and Uppanar estuaries were 52 and 14 species respectively. Diversity indices were high in Vellar estuary (H'log2-4.264 +/- 0.21, d-5.782 +/- 0.65, J-0.964 +/- 0.008, Lambda'-0.02 +/- 0.004 and sPhi+-1906 +/- 264.99) and low in Uppanar estuary (H'log2-0.941 +/- 0.27, d-1.130 +/- 0.42, J-0.418 +/- 0.05, Lambda'-0.70 +/- 0.07 and sPhi+ 433 +/- 102.74). While the BI (AMBI-1.03 +/- 0.19) and M-AMBI (M-AMBI-0.90 +/- 0.06) values of Vellar estuary corresponded to the undisturbed nature and high/good estuarine ecological quality respectively, the above values in Uppanar showed the polluted (AMBI-4.47 +/- 0.14) and poor/bad status (M-AMBI-0.22 +/- 0.04) of estuarine ecological quality. Recently introduced tools such as AMBI & M-AMBI have clearly brought out the impaired health of Uppanar estuary and healthy nature of Vellar estuary.
