Description:
In order to study the ecological status of western and estern estuary of of Hormozgan, sampling of sediments in
four stations in each estuary was carried out seasonally from spring to winter of 2016. In this study, 118 species
of polychaets, 71 species 0f crustacea, 25 species of bivalves and 20 species of gastropods were introduced. The
average density of macrobenthos population in indicated that the station 2 in Laft with 1522, station 1 in Khoran
with an average of 3397 and station 4 of Yekshabe and Tiab with a mean of 980 and 1577 inm-2 respectively
were the most densely populated. In laft, Margalef index, with the values of 7.44 in station 2, Shannon with 2.68
in Station 3, Pielo-Evenes with 0.77 in station 3, Simpson index with 0.43 in station 4 and w- Statistic with a
value of 0.3 at station 3, In khooran Margalef index with a value of 43.4 at station 2, Shannon with a value of
2.78 at station 2, pielo-Evenes with a value of 0.66 at station 2, Simpson index with a value of 0.61 at station 1
and index w -statistic with a value of 0.1 at station two, In Yekshabeh, Margalef index with 8.83 in station 4,
Shannon with a value of 3.68 at station 4, Pylou-Evenes with a value of 0.88 at station 4, Simpson index with a
value of 0.11 at station 3 and w- Statistic with a value of 0.24 at stations two and four, and im Tiab, the Margalf
index with a value of 10.46 at station 4, Shannon with a value of 3.47 at station 4, Pylou-Evenes with a value of
0.83 at station 2, Simpson index with a value of 0.17 at station 1 and index w -statistic with the value of 0.29 at
station 4 were the highest in this survey. Totaly, these quantitative and qualitative indices based on weight ABC
for Laft and Khoran discribed relatively contaminated and for Yekshabe and Tiab discribed non-contaminated
condition In sum, these quantitative and qualitative indices based on ABC weight for leachate and dough
conditions were relatively contaminated and for one and the other cobbins, non-contaminated conditions, due to
which can be adjacent to the West Bank with the Persian Gulf, low depth and limited water exchanges, and as a
result , the accumulation of materials from pllutands in thisestuaries and their impact onbenthic communities.
