According to the communique, the overall urban air quality in the country improved in 2015. The average concentration of PM2.5 in the first batch of 74 cities that implemented the new ambient air quality standards was 14.1% lower than that in 2014. Of the 338 prefecture-level cities in China, 73 cities had environmental air quality standards, accounting for 21.6%; 265 cities had exceeded ambient air quality, accounting for 78.4%. 480 cities (districts, counties) carried out precipitation monitoring, acid rain 22.5% of the city, acid rain frequency is an average of 14.0%, the overall type of acid rain is still sulfuric acid, acid rain pollution is mainly located in the south of the Yangtze River - east of the Yunnan-Guizhou Plateau.
967 state-controlled surface water monitoring sections (points) in 423 major rivers and 62 key lakes (reservoirs) across the country have carried out water quality monitoring, and 64.5% of the water quality sections I-III, IV-V, and V-grade respectively accounted for. , 26.7%, 8.8%. In the groundwater aquifer system as a unit, among the 5118 groundwater quality monitoring points that are mainly superficial shallow groundwater and medium-deep groundwater with confined water as the monitoring target, the proportion of water quality-grade monitoring sites is 9.1%. The proportion of monitoring sites was 25.0%, that of better-level monitoring sites was 4.6%, that of poor-grade monitoring sites was 42.5%, and that of extremely-level monitoring sites was 18.8%. 338 cities above prefecture level have carried out water quality monitoring of centralized drinking water sources. The total amount of water taken is 35.543 billion tons, and the standard water intake is 34.506 billion tons, accounting for 97.1%.
In winter, spring, summer and autumn, the area of ​​bad seawater in the fourth category accounted for 2.2%, 1.7%, 1.3% and 2.1% of the area under China's jurisdiction. The polluted sea areas are mainly distributed in the offshore waters of Liaodong Bay, Bohai Bay, Laizhou Bay, Jiangsu Coast, Yangtze River Estuary, Hangzhou Bay, Zhejiang Coast, and Zhujiang Estuary.
The average rate of day-to-day monitoring of 308 cities above the prefecture level with sound environment monitoring in the functional areas was 92.4%, an increase of 1.1 percentage points from 2014; the average monitoring rate of night-time monitoring was 74.3%, which was an increase of 2.5 from 2014. Percentage. The standard rate of acoustic environmental quality in all types of urban functional areas was higher than that at night.
The level of environmental ionizing radiation in the country is within the background fluctuation range, and the level of environmental electromagnetic radiation is lower than the corresponding national limit.
By the end of 2015, a total of 2740 nature reserves of various types and levels were established across the country, with a total area of ​​approximately 14.703 million hectares.

The existing forest area of ​​the country is 208 million hectares, the forest coverage rate is 21.63%, and the total standing timber volume is 16.333 billion cubic meters. The area of ​​grassland is nearly 400 million hectares, accounting for 41.7% of the country's land area.
Thirty provinces (autonomous regions and municipalities) suffered floods and floods. Compared with the historical average, the number of deaths due to disasters decreased by 76%, the lowest in history; the number of affected people, affected areas, and collapsed houses decreased by 46%, 45%, and 85%, respectively. The overall drought situation in the country was generally mild. The annual acreage of farmland affected by drought and the number of people and livestock drinking water were all significantly lower than in the same period of the year. Compared with the year-round, the area affected by crops, the loss of food due to drought, and the number of people suffering from drought and drinking water decreased by 52% and 51 respectively. %, 65%. Affected by El Niño, the forest fire safety rating has been persistently high since the beginning of spring in 2015. In the summer, the lightning intensity in the key forest areas in the north has been rapidly high; in the autumn, the precipitation in the south continues to be high; when it enters the winter, the temperature in the north is high. Cold air activity is less frequent and weak. It is expected that the strong El Nino will continue to decline, but the impact on the climate will continue.
