Performance Evaluation of Watershed Water Pollutants Total Emission Reduction Based on Cloud Theory
Yue Peng · Modern Agricultural Science and Technology · 2013
Being fully considered of the performance evaluation characteristics of watershed water pollutants total emission reduction,the cloud theory which combined the ambiguity and the randomness of uncertainty concept were introduced.Based on cloud theory,the cloud gravity center evaluation methods was proposed in order to evaluate the performance evaluation management level of water pollutants emission reduction of Qinghe basin during 2005—2007 and 2008—2010.The results showed that the performance management level of 2008—2010 were greatly improved than 2005—2007,but it also had a big gap to the ideal state.In addition,the cloud gravity center evaluation methods as a effective mathematical tool to deal with the uncertainty and ambiguity information could convenient to realize the transformation between qualitative concepts and their quantitative expressions,so that this method was feasibility and effective for the evaluation of water environment management.
