During the "13th Five-Year Plan" period, the city's ecological environment status index increased from 64.2 in 2015 to 70.2 in 2020, an increase of 9.3%; the area of Beijing accounts for about 0.17% of the country's land area, and the number of plant species accounts for about 8% of the total number of the country; at present, the proportion of birds with accurate records in Beijing accounts for more than one-third of the number of bird species in the country, which is unique in the northern cities of China... These are all microcosm of Beijing's biodiversity.
May 22 will usher in the International Day of Biodiversity, the reporter learned from the Beijing Municipal Bureau of Ecology and Environment held a press conference in the morning, the city has formulated a biodiversity survey plan for 2021-2025, during the "14th Five-Year Plan" period is expected to achieve full coverage of the survey grid, dynamically find out the background of the city's biodiversity, and form a series of survey reports.
Finding out the "home base" of biodiversity is an important basis and prerequisite for carrying out conservation work. Cao Zhiping, director of the Beijing Municipal Natural and Ecological Protection Department, introduced that in 2020, the Municipal Bureau of Ecology and Environment divided the city into 212 grids, and carried out a comprehensive survey of the diversity of some grid ecosystems and the diversity of mammals, birds, amphibians, fish, insects, algae and other species, and recorded a total of 5,086 species in the field.
Cao Zhiping said that in the central urban area, the investigation team found animals such as the northeast hedgehog and weasels, and also found birds of prey such as the Japanese pine sparrowhawk and the red-footed falcon, reflecting that in recent years, the central urban area has increased the urban green area in a variety of ways, providing a richer habitat for wild animals.
In the plain area, forest birds such as bald eagles and woodpeckers, amphibians and reptiles such as black-spotted side-fold frogs, Chinese forest frogs, and Chifeng golden snakes, as well as fish such as horsefish and blackfin carp are frequently "infested", indicating that Beijing has expanded its green ecological space and enriched biodiversity in recent years through afforestation and afforestation of millions of mu, the construction of country parks and the restoration of rivers and lakes and wetlands.
"The ecological conservation area is a biodiversity-rich area in Beijing, and the areas with the best ecosystem quality in Beijing have been effectively protected by strengthening the construction of nature reserves, habitat protection, water ecological restoration and other measures." For example, Cao Zhiping introduced that the investigation found threatened species such as the blue-headed diving duck, the brown horse chicken, the large-flowered orchid, and the rotunda shellfish, as well as the ocelot, the spiny horn snake spring fly, the purple lime and other national key protected wild animals and plants, as well as a large number of wild boar, soft jujube kiwifruit, eleutheroccus and other wild animals and plants under key protection in Beijing.
Rich biodiversity is inseparable from a good ecological environment. The data shows that the index of beijing's ecological environment has continued to improve, from 64.2 in 2015 to 70.2 in 2020, which has achieved six consecutive years of improvement. Specifically, the index of the functional core area, the central urban area and the plain area of the capital has increased greatly, of which the plain area has increased the most, reaching 16.9%, the capital functional core area has increased by 15.1%, the improvement of the ecological environment is significantly higher than the average increase of the city, and the excellent ecological environment service capacity has been further improved.
