At present, Ministry of Ecology and Environment is carrying out the demarcation work of national ecological red line. A total of 15 provinces, including Beijing-Tianjin-Hebei, Yangtze River Economic Belt and Ningxia, have completed the demarcation work by the end of last year, and the other 16 provinces will complete theirs by the end of this year. On this basis, a picture of the national ecological red line will be formed. The ratio of national ecological protection red line area will meet or exceed the target determined by the central government, 25% of the national land area.

First, demarcating and strictly complying with the red line of ecological protection is an important strategic measure to retain lucid waters and lush mountains. The sources of major rivers, barriers of ecological security, and various protections of rivers and lakes in China are important parts of national security. The demarcation of ecological protection red line is to implement strict protection of these important areas and leave innocent nature for future generations.

Second, demarcating and strictly complying with the red line of ecological protection is an effective method of improving system functions. The ecological protection red line is the bottom line and lifeline for ensuring and maintaining national ecological security. The demarcation of ecological protection red line is to respect the laws of nature, preferentially protect good ecosystems and important habitats, classify and repair damaged ecosystems, improve the supply capacity of ecological products, and leave a sustainably developing Green Bank for future generations.

Third, demarcating and strictly complying with the red line of ecological protection is an important support for supervision and management of the national resources within territory. The ecological protection red line is the most important and core part of the ecological space. Build a scientific and reasonable urbanization promotion pattern, agricultural development pattern, and ecological security pattern to ensure national and regional ecological security. The demarcation of ecological protection red line will facilitate the establishment of national spatial land protection system, which is based on spatial planning and uses land control as the main means. The first is to carry out scientific evaluation; the second is to reasonably determine the scope; the third is to conduct a boundary survey and set boundary makers.

The ecological protection red line is the basis, and strict compliance is the key. It is necessary to implement the whole-process supervision¬, precaution in advance, supervision in progress and punishment afterwards; and to establish a severe ecological protection red line system..

To ensure that the demarcation and survey conducting tasks of national ecological protection red line are fully completed in 2020, use the 2020 Convention on Biological Diversity and the 15th Conference of the Parties to jointly discuss new models and methods for global ecological protection, commune concepts including lucid waters and lush mountains are invaluable assets; the harmonious coexistence of man and nature; the ecological protection red line, and make our work more solid and effective.

In order to effectively implement the two-mountain theory and create more two-mountain samples, the Ministry of Ecology and Environment proposed in September 2017 to conduct a pilot construction of the two-mountain practice nationwide. 13 regions were selected to be practice bases , such as Saihanba Mechanical Forest Farm in Hebei Province; Youyu County, Shanxi Province; Sihong County, Jiangsu Province; Anji County, Quzhou City, Zhejiang Province; Jingde County, Anhui Province; Changting County, Fujian Province; Jing'an County, Jiangxi Province; Dongyuan County, Guangdong Province; Jiuzhaigou County, Sichuan Province; Wudang District, Guiyang City, Guizhou Province and Liuba County, Sshanxi Province. This brought theoretical innovation to practical innovation and promoted the transformation from lucid waters and lush mountains to invaluable assets.

First, consciously improve the political position and give full play to the leading role of two-mountain theory.

Second, strengthen environmental governance and ecological restoration, constantly tamp the ecological basis of lucid waters and lush mountains.

Third, continuously optimize the economic structure and persist in enriching and benefiting people in an eco-friendly way..

Fourth, continue to deepen reforms, and strive to establish a guarantee for the system that deeply implements the two-mountain theory.

Fifth, cultivate an ecological culture and extensively encourage the whole society to participate in the two-mountain practice.
