Abstract:

The comprehensive ecological evaluation of the Sanjiangyuan Region is conducted based on large amount of realtime ecological monitoring data. Firstly, the monitoring data obtained from WSN are normalized to eliminate the difference of type and dimension, and a comprehensive ecological evaluation model is established according to the available ecological monitoring sensor and the ecological study of the Sanjiangyuan Region. Then the weights of all indexes are scientifically determined with AHP. Finally the comprehensive ecological evaluation is conducted with a linear strategy of comprehensive evaluation, and an example is given to demonstrate the evaluation process. The evaluation method put forward in this paper determinates the index weight with AHP. It makes it scientific to quantitatively evaluate the comprehensive ecology of the Sanjiangyuan Region, and is a theoretical and practical guidance for the utilization of the remote realtime ecological monitoring data of the Sanjiangyuan Region based on WSN.
