China releases blue book on ecological conservation red lines

China's ecological conservation red lines reached about 3.19 million square kilometers, covering all 35 key areas for biodiversity conservation and more than 90 percent of typical ecosystems, said a blue book released on Tuesday.

The Ministry of Natural Resources released the Blue Book of China's Ecological Conservation Red Lines, marking the country's first publication of such kind.

Among them, the land ecological conservation red lines cover about 3.04 million square kilometers, accounting for over 30 percent of the country's land area.

The marine ecological conservation red lines cover an area of about 150,000 square kilometers.

By drawing the red lines, the country aims to prioritize the conservation of areas with significant functions, including water conservation, biodiversity maintenance, soil and water conservation, wind and sand fixation, and coastal protection.
