AbstractAlong with the development and progress of society economy,dams have been playing increasing important roles, and so does the Three-Gorges Dam. Inevitably, hydrobios, hydrochemistry and other key physico-chemical factors of water body were altered. In order to evaluate these changes,many pursuers study water quality through bio-detectors and physico-chemical factors. But both of the two methods failed to compare from different studies since different bio-detector and physico-chemical factors were adopted. In this paper,the author tries to probe into a new way through discussing the relationship between DNA structure of plankton community and physico-chemical factors in the Three-Gorges Reservoir region (TGRR).Random amplified polymorpbic DNA ( RAPD) was used to analyze DNA structure of plankton community, and got the result that 7 locations clustered into 3 groups. Station D and E clustered together at first, then A and C joined in this group; B and F was as another group,and G was different from all the others. While the physico-chemical factors clustering showed that station B and C clustered as a group at first,then adding D into this group; G and F clustered into another group; A and E was other two separated groups. After comparing, some stations such as A, C, D and E clustered close in RARD while were away fram each other in physico-chemical factors. On the other hand, B-G and F-G clusteried apart from each other while reversed in physico-chemical factors analysis. All the results indicated two possibilities: One was that DNA structure of plankton community under RAPD analysis and physico-chemical factors analysis of water body in the TRGG correlate negatively; the other was because of the instantaneous samples,some natural and artificial factors,such as water flow, weather,man-made operations and so on,might affect the experiment results to some extent. Accordingly,new information about physico-chemical factors has been obtained, which is beneficial to affirm relationship of DNA structure of plankton community and physico-chemical factors. Further more,it is better for establishing a new assessment system of water quality.
