"Ministry of Natural Resources 2020 Satellite Remote Sensing Application Report" was released yesterday (August 20). The report shows that my country's natural resource satellite observation capabilities have been further improved, and satellite sharing has formed a scale.
The Ministry of Natural Resources stated that there are currently 19 natural resources remote sensing satellites in orbit, and my country’s remote sensing satellite observation capabilities for natural resource surveys have been further improved.
In addition, satellite sharing has formed a scale, basically realizing the connection of natural resource system land, surveying and mapping, ocean, geology and mining, forestry and grass data images, and established natural resources provincial satellites in 31 provinces, autonomous regions and municipalities in the country and Xinjiang Production and Construction Corps. Application Technology Center. Over the year, land satellite data pushed more than 1.73 million, and marine satellite data pushed more than 2.74 million. The
report also stated that natural resource remote sensing satellites provide comprehensive services for natural resource management, and their application scope, scale, and depth have been further expanded. They have become important for natural resource survey and monitoring, spatial planning, ecological restoration, farmland protection, surveying and mapping geographic information, sea islands, etc. Technical support and regular information guarantee.
With the further improvement of natural resource satellite observation capabilities, my country's remote sensing application has also achieved remarkable results, providing important data, information and technical support for special remote sensing monitoring of major geological hazards and the status of mangrove resources.
The Ministry of Natural Resources stated that in 2020, satellite remote sensing will be used to complete the identification of hidden hazards in 9 provinces and cities with high risk of geological disasters across the country, covering five types of typical types including the upper reaches of the Yellow River, Sichuan strong earthquake area, southeastern Tibet, northwestern Yunnan, and the Three Gorges reservoir area. In the geological disaster distribution area, a total of 8,450 suspected hidden dangers were identified, mainly high-level remote landslides, large-scale unstable slopes and other types. At the same time, the comprehensive remote sensing identification and monitoring of major geological hazards has also been promoted and applied to 14 provinces where the impact of geological hazards is prominent, becoming an important technical means for the new round of geological hazard risk surveys.
At the same time, the state has also used 2m domestic remote sensing satellite imagery to carry out the national mangrove resource satellite remote sensing monitoring. The results show that the total area of mangroves in my country is increasing. From 2018 to 2020, the country’s newly increased mangrove area is close to 490 hectares, of which artificial planting restoration is the main type of increase. The area is about 290 hectares, accounting for about 60%, mainly distributed in Guangdong, Guangxi, Hainan, Fujian, Taiwan and Hong Kong Wait for the place. The Ministry of Natural Resources said that in the future, it will further promote the deep integration of satellite remote sensing and natural resource management, and further enhance the ability of natural resource management observation.
