The Strategy to Construct the Urban Ecological Civilization Strengthen the education of citizen’ quality, develop awareness of ecological civilization. [5]In order to raise people’s ecological ethics should set up the new views of system , values, economic, spending and science technology.
Advocate the new consumption mode can help people get rid of the endless pursuit of material desires, guiding people and nature to harmonious coexistence to construct the party and the national to resource conservation and environment friendly society.
Today, in the increasingly serious ecological crisis, ecological criticism in guiding people to respect the nature, love nature, return to nature, will play more and more important role in building a green lifestyle Acknowledgements This work was financially supported by the Shenyang Engineering Institution Natural Science Foundation (RWQN-1312).
