A Systematic Assessing Model of Regional Aquatic Ecosystem Health Based on Entropy Weight

With the social development and more high demand of sustainable development, more complicated problems on water ecosystem need to be deal with. To a regional sustainable development, water is the most basic condition and the regional aquatic ecosystem health is the constraint to the development. In this paper, the systematic assessment model(SAM) is proposed to assess the status the aquatic ecosystem health using systemic method. In the SAM, the indexes include 5 factors. Besides the factors about water,the human activities and area of the forest etc, are included in the index system. The factors on the system restore also take into account in the system.Through the experiment, SAM is more reasonable and comprehension than the methods which only use the water quality to assess the status of aquatic ecosystem health.
