摘　　要：基于大量实时生态监测数据实现了对三江源地区的综合生态评价。首先对通过WSN获得的不同类型和不同量纲的数据进行统一的规范化处理,并根据可用的生态监测传感器类型和三江源地区生态研究成果,构建了综合生态评价模型,然后基于AHP原理科学地确定各指标的权值,最后采用线性综合评价策略进行综合生态评价,并通过实例应用说明了评价过程。该评价方法应用AHP确定权值,科学地实现了对三江源地区综合生态的量化评价,对基于WSN的三江源远程实时生态监测信息的开发利用具有重要的理论和实际指导作用。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.
