China has established about 10,000 protected areas of all types, which account for about 18 percent of the country's total land area, said a white paper released on Friday by the State Council Information Office.

The well-planned protected areas system has brought 90 percent of terrestrial ecosystem types and 71 percent of key state-protected wildlife species under effective protection, according to the white paper titled "Biodiversity Conservation in China."
