This paper has constructed the index system of ecological civilization health quotient and quantitatively got each index proportion of the system with application of analytic hierarchy process(AHP). The value of ecological civilization health quotient index is calculated with the fuzzy analysis method. The health state of ecological civilization is judged by the positive and negative ecological civilization health quotient index. This paper has selected the data from 2009 to 2013 to calculate the whole health status of ecological civilization of our country. The conclusion is that our country had transformed from the unhealthy status(ecological civilization health quotient index is-0.133) into the sub-health state(ecological civilization health quotient index is 0.191, but its internal rule layers are negative) during the fi ve years. We should construct the ecological civilization mainly from two aspects of resource conservation and ecological behavior civilization in the future to build a beautiful China.展开更多
