A nature reserve refers to the land, land water body or sea area where representative natural ecosystems, natural concentrated distribution areas of rare and endangered wild animal and plant species, and natural relics of special significance are located, and a certain area is legally designated. Areas to be specially protected and managed.
[Grading] According to the principle of division of powers, my country's nature reserves are divided into 4 levels: national level, provincial (autonomous region, municipality) level, city (autonomous prefecture) level, county (autonomous county, banner, county-level city) level. manage.
[Division] In order to effectively coordinate the contradiction between protection and development in nature reserves, my country refers to the successful experience of the "Man and the Biosphere Program", and divides the nature reserves into core areas, buffer areas and experimental areas according to the main functional differences. Implement different management policies for each functional area.
The geographic remote sensing ecological network www.gisrs.cn is based on the list of nature reserves issued by the Department of Environmental Protection, the Department of Forestry and other departments, as well as the functional zoning map of nature reserves. Under the 2000 National Geodetic Coordinate System (CGCS2000), based on high-resolution satellite images, Through the geographical matching of the points with the same name on the map and the error calculation between the latitude and longitude grids, the georeferencing between the functional zoning map of the nature reserve and the satellite image is realized. Then, polygonal feature vectorization is performed for the core area, buffer area and experimental area of each nature reserve. Finally, the topology check is performed on the polygonal elements, and after the modification is qualified, the production of the spatial distribution data of the nature reserve is completed.

1. Geographic Remote Sensing Ecological Network www.gisrs.cn
At the same time, the geographic remote sensing ecological network www.gisrs.cn shares a lot of scientific data in the field of geographic remote sensing (land use data, npp net primary productivity data, NDVI data, meteorological data (precipitation, temperature, evapotranspiration, radiation, humidity) , sunshine hours, wind speed, water vapor pressure data), runoff data, night light data, statistical yearbook, road network, POI point of interest data, GDP distribution, population density distribution, tertiary watershed vector boundary, geological disaster distribution data, soil Geographical data such as type, soil texture, soil organic matter, soil PH value, soil texture, soil erosion, vegetation type, distribution of nature reserves, distribution of building contours, etc., as well as operation tutorials on gis and remote sensing, national monthly average solar radiation Spatial distribution data/monthly rainfall distribution/monthly average temperature distribution) national aviation and airport distribution vector data/tourist attraction poi/national port terminal distribution/subway station distribution/train station distribution/2020 POI vector data.

4. The University of Maryland data set
UMd based on the 5 bands of AVHRR data and NDVI data has been combined to propose a data matrix again, and the global land cover classification has been carried out with the method of classification tree. Its purpose is to hope to build a dataset with higher accuracy than past data
