Abstract: Wetlands play a key role in the ecological conservation, in environmental quality improvement, and in human habitat environment improvement. Primer field investigations, primary survey and series of stakeholder meetings were utilised to evaluate the performance of the wetland. It was done using the complex index system covering wider aspect to correlate the comparative status of both Tamil Nadu and Puducherry zone of the Ousteri wetland. Compared with the researches applying the ecosystem service evaluation method, the proposed scoring method in this study can evaluate on some important performance indices (aquatic vegetation coverage, plant community integrity, integrity of management operating system, stakeholders feedback on the wetland protection, public satisfaction) that cannot be ignored and unable to be transformed to a monetary form. The Delphi method was used to screen preset 35 subindicators prior to evaluation. By using Delphi and Analytic Hierarchy Process method, as well as the weighted linear combination model, the ecological-economic-social performances were obtained. This indices system was applied to the case of Ousteri wetland with respect to Puducherry and Tamil Nadu scenario separately. With the help of the Evaluation Index system (EIS) established in this study, decision makers can obtain more omni-visual information so that an ecological subsidy policy by incorporating rewards and punishments mechanisms according to the performance evaluations can be formulated to enable the greatest returns on investment in the wetland conservative measure.
