The Third Plenary Session of the 18th CPC Central Committee put forward the strategic requirements of “delineating and strictly observing the Ecological Conservation Redline”. The “Nineteenth National Congress” report emphasizes promoting the overall protection of ecosystems，“coordinating the management of landscape and forestry lakes and grassland，and implementing the most stringent ecological environment. The Ecological Conservation Redline has become an important starting point for the construction of national ecological civilization，and has been upgraded to the national strategic to become the national ecological security line. In this context，Shanghai actively carried out the delineation of Ecological Conservation Redline，which is not only a positive response to the country’s strategic requirements for promoting ecological civilization construction，accelerating the reform of the ecological civilization system，and implementing the Yangtze River Economic Belt’s protection. It is also an important measure for Shanghai to maintain the bottom line of urban ecological security and achieve excellence in global urban construction. In February 2018，the State Council officially approved the Shanghai Ecological Conservation Redline Delineation Plan. The next step is to establish and improve the Ecological Conservation Redline management system and promote Shanghai ecological protection red line. We thus discussed the management system from 4 dimensions and discussed the management countermeasures from 8 aspects. In order to provide support for Shanghai to strictly adhere to the Ecological Conservation Redline and ensure ecological security.
