BEIJING - China's State Council Information Office Friday issued a white paper to introduce the country's actions on biodiversity conservation and share its achievements in the sector.

The white paper, titled "Biodiversity Conservation in China," said that China preserves biodiversity with creative and up-to-date measures, forming a new pattern of biodiversity conservation.

Here're some of the highlights:

China contributes 10% of world's new plant varieties in past decade

China has contributed up to 10 percent of the new plant varieties identified worldwide in the past decade.

In this period, the country has identified about 200 new varieties of plants per annum, said the white paper.

China takes lead to propose, implement red line strategy for ecological conservation

China was the first in the world to propose and implement the red line strategy for ecological conservation. The country has also designated priority areas in biodiversity protection. These measures have contributed to the conservation of key natural ecosystems, biological resources, and habitats for key species.

Protected areas account for 18% of China's land area

China has established about 10,000 protected areas of all types, which account for about 18 percent of the country's total land area.

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.

China contributes most to world's green area growth in 2000-2017

The country has contributed about 25 percent of global vegetation growth in the reporting period, the biggest share among all countries.

China's forest coverage and forest reserve have both maintained growth for the last 30 years, and the country has realized the largest growth in forest resources among all countries in the world.

Remarkable results in pollution control

The country has improved the quality of air, water and soil. 

In 2020, China's average concentration of ambient particulate matters, or PM2.5, declined by 28.3 percent from 2015, while the percentage of days with good air quality rose by 5.8 percentage points from 2015.

The combined proportion of state-controlled water sections with good-quality surface water was 83.4 percent last year, up by 17.4 percentage points from 2015, while that of good-quality offshore waters was 77.4 percent in terms of area, up by 9 percentage points from five years earlier.

In 2020, the safe utilization rate of contaminated arable land and that of contaminated land both exceeded 90 percent.
