June 4, Vice Minister of environmental protection Li Ganjie said today that the national environmental quality situation in General has improved, but the situation of the ecological environment is still grim, still faces many difficulties and challenges. Soil erosion in the country has a total area of 295 million hectares, covers a land area of 30.7%.
New Office held a news conference today, Deputy Minister of environmental protection Li Ganjie Secretary Zhao Yingmin, Ministry of environmental protection, pollution control, environmental monitoring Secretary Luo Yi to attend on the 2013 China environmental situation bulletin, and answering a reporter's question.

Pearl River, rivers in Southwest and Northwest Rivers for water quality is excellent, and Zhejiang, Fujian and the Yangtze River River water quality good, Yellow River, huaihe and liaohe, Songhua River, light pollution, pollution in the haihe River. In monitoring the nutritional status of 61 Lake (reservoir), the eutrophication status of Lakes (reservoirs), 27.8% of mild to moderate eutrophication eutrophication of these lakes (reservoirs) 26.2% and 1.6%, respectively. 4,778 groundwater monitoring sites in the proportion of poor and extremely poor water quality monitoring points to 59.6%.
Second, national coastal waters generally fair. Ratio of sea water, to 66.4% one or two classes, three or four categories of water level for 15%, inferior ratio of four categories of water, to 18.6%. In the four areas, water quality of the Yellow Sea and the South China Sea offshore well, coastal water quality in the Bohai Sea, the East China Sea coastal water quality very poor. 9 key Bay, Liaodong Bay, Bohai Bay, and poor water quality in Jiaozhou Bay, Yangtze River estuary, Hangzhou Bay and the very poor water quality of minjiang River and Pearl River mouth.
Third, national ambient air quality in the city is at stake. Under the new ambient air quality standards (GB 3095-2012) for SO2, NO2, PM10, PM2.5, CO and O3 pollution assessment, 74 new standards for monitoring the implementation of the first phase of urban ambient air quality standards the city compared to 4.1%, other 256 municipalities to implement air quality and old standards, reaching the city for 69.5%. Acid rain distribution mainly concentrated in areas along the Yangtze River and South of the middle and lower reaches of the region, acid rain area covers a land area of 10.6%.
Four is the national urban sound environmental quality overall is good. National City daytime sound environment quality of 76.9% for the first and second grade 97.8% daytime road traffic acoustic environmental quality of the city for the first and second level; national urban Ribbon daytime sound environment of compliance with 91.1%, evening standard rate of 71.7%.
Radiation of five national environmental quality overall is good. Maintained at natural background ionizing radiation level fluctuations within nuclear installations, nuclear technology projects overall no significant changes in ambient levels of ionizing radiation. Environmental electromagnetic radiation level in General is better, electromagnetic launch facility overall no significant changes of ambient electromagnetic radiation levels.
Six is the environmental situation is still grim. Disturbing the soil environmental quality of cultivated land, regional degradation problem is more serious. Year net decrease of 80,200 ha of cultivated land area of the country. Soil erosion in the country has a total area of 295 million hectares, covers a land area of 30.7%.
Seven forest and grassland resources remained steady. 208 million hectares of national forests, the forest coverage rate of 21.6%, total accumulative 16.433 billion cubic metres of standing timber, forest 15.137 billion cubic meters. Area of nearly 400 million hectares of grassland, covers a land area of about 41.7%.
Eight is the stability of ecological environment quality. National eco-environmental quality in a benign and mainly covers a land area of about 67.2%. By the end of 2013, s establishment of nature reserves in various types, different levels of 2,697, 146.31 million hectares of the total area, land area total national land area 14.8%; 407-a total of national nature reserve, an area of 94.04 million hectares.
