 Jiangxi forest ecological and meteorological observation base: most of Nanchangs pollutants come from other places.


In November 1st, the promotion of meteorological support services for national ecological civilization construction was held in Jingan County, our province. According to reports, as one of the first batch of national ecological civilization pilot areas, our province has achieved 89% of the excellent air quality rate and 92% of the national assessment section water quality rate through a series of measures in recent years, ranking the forefront of the country.

In addition, the newly built Jiangxi Forest Eco-meteorological Observation Base (Jingan) is also appearing in dense forests in deep mountains. The observation results of this base can not only provide basic data for assessing the changes of ecological red line protection areas in Jiangxi Province, the functions and values of forest ecosystems, but also provide basic data support for the assessment of pollutants in Nanchang mostly coming from other places. This judgment provides the best data support.

ecological environment

Many excellent indicators rank among the highest in the country.

At the end of 2014, our province was approved by the National Development and Reform Commission and other six ministries and commissions as the first demonstration area of national ecological civilization; in 2016, our province was once again set up by the central government as one of the first national experimental areas of ecological civilization; in 2017, China Meteorological Administration ranked our province as the first pilot province of meteorological guarantee service for the construction of national ecological civilization. From Pioneer Demonstration Zone to Test Zone, Jiangxis position in the national ecological civilization construction pattern has been further enhanced.

Climate is one of the most active factors affecting ecosystem, and it is also an important part of the construction of ecological civilization. According to reports, in recent years, our province has vigorously promoted the modernization of meteorology, implemented the key project of the 13th Five-Year Plan of Meteorology, invested 608 million yuan locally, initially constructed the ecological observation network of forests, wetlands, alpine meadows, farmland and cities, and formed a number of ecological meteorological service brands with Jiangxi characteristics.

At the same time, our province actively explores the green water and green hills as the development path of Jinshan Yinshan, intensifies the ecological restoration efforts, promotes the Yangtze River Economic Zone to jointly grasp the great protection, resolutely fights against the blue sky, eliminates inferior V-type water bodies and soil pollution prevention and control, and achieves better results in the construction of ecological civilization.

At present, the excellent rate of air quality in Jiangnan Metropolitan Daily reaches 89%, the excellent rate of water quality in national assessment section reaches 92%, and the forest coverage is stable at 63.1%.

Ecological cloud

Providing security for green development

Jingan County is one of the best ecological counties in our province. The forest coverage rate is as high as 84.1%. The construction of ecological civilization is undoubtedly in the forefront of the province. On the morning of November 1, delegates from all over the country visited Jingan Eco-Cloud Platform, Baofeng Eco-Town and Jiangxi Forest Eco-meteorological Observation Base, and realized the charm of Jingan as a natural oxygen bar.

Through 30 cameras and 260 sensors, Eco-Cloud is connected to water, meteorology, environmental protection, Skynet and other sub-clouds, and online monitoring is implemented to realize the function ofThousand-mile-eye. On the screen of Jingan ecological cloud exhibition hall, pictures of river banks, villages and ancient trees are displayed in real time. According to local officials, Jingan County has established 13 monitoring and early warning projects covering meteorology, forestry, water resources and other fields. Through the ecological cloud platform, equipment perception, data analysis and processing, and abnormal information warning and alarm can be realized, security risks can be predicted in advance, and security guarantees for green development can be provided.

Baofeng is a famous ecological town in Jingan and even Yichun. In recent years, in order to promote the construction of ecological civilization in Baofeng, meteorological departments have carried out climate quality assessment services for local famous and excellent agricultural products, and issued excellent climate labels for products that meet the relevant conditions of planting climate, which has greatly enhanced the value of agricultural products; in the areas of issuing early warning and carrying out scientific popularization of meteorological disaster prevention, etc., Qi has been widely used. Image departments also provide scientific evidence and guidance. In addition, Jingan County Meteorological Bureau has also installed a township meteorological service platform, so that people can get real-time information about the weather, weather forecast and farming suggestions.

Observation base

Air pollution in Nanchang is confirmed from abroad.

Jiangxi Forest Eco-meteorological (Jingan) Observation Base was established in October this year and is located at Dadongkou Forest Protection Site of Zhoufang Branch of Jingan Ecological Public Welfare Forest Farm. Base observation projects mainly include meteorological elements inside and outside forests, forest gradient meteorological elements, air quality (PM2.5, PM10 concentration, etc.), atmospheric negative oxygen ion concentration and so on. In addition, the Provincial Meteorological Bureau has installed an aerosol lidar system, which can detect the vertical transport flux of air pollutants in Nanchang.

According to Yin Jianmin, chief engineer of Jiangxi Meteorological Bureau, Nanchang is just in the downwind direction of Jingan, so although the detection equipment is located in Jingan, the pollutants monitored will eventually float to Nanchang with the wind. In fact, there is not much haze emission in Nanchang and even in Jiangxi itself. According to our calculation, more than half of the haze in Jiangxi comes from outside the province, but we need data to prove it. Yin Jianmin said that the data monitored by the system can provide the best evidence for the statement that most pollutants in Nanchang come from other places. In addition, the observation results of the whole base provide basic data support for scientifically and dynamically evaluating the changes of eco-red line reserve in Jiangxi Province, the functions and values of forest ecosystem, the impact of meteorological disasters on forest ecosystem, and the regional transportation of atmospheric pollutants, so as to improve meteorological support services for the construction of ecological civilization in Jiangxi Province.
