Establishment of evaluation indicators of ecological engineering methods

This study has established an initial methodology of assessment, based on the watershed scale, using several related indicators and classifying them biological and non-biological.Furthermore, we should combine the ecological engineering criteria so as to assess the efficiency of such methods.We establish a river water-quality monitoring project to know the different water qualities during, before and after its construction, and avoid destroying the river ecological environment.The ecological engineering methods should have different scales and notions in choosing the crieria, and mainly attach importance to the integrity of the watershed management.The decision-makers can refer to and use the different assessment criteria in working out their plans, meanwhile, offer the project-planned parameters with the ecological monitoring indicators in order not to destroy the ecological environment during the construction.
