Spatial distribution dataset of ecosystem quality in Sanjiangyuan National Park (2010-2020)

As one of the first batch and largest national parks in China, Sanjiangyuan National Park quantitatively evaluates the quality of the ecosystem. It not only clarifies the ecological background status, but also understands the ecological construction status of the national park, providing a healthy and stable ecosystem, coping with climate change, and warning ecological security risks for Sanjiangyuan National Park Mitigating the degradation process and other aspects can provide scientific basis and decision-making services. This dataset selects the vegetation coverage and net primary productivity of Sanjiangyuan National Park from 2010 to 2020 as key indicators to measure the ecosystem quality of Sanjiangyuan National Park. Among them, vegetation coverage refers to the proportion of the vertical projection of vegetation on the ground to the total area of the study area, calculated using the pixel binary model. Net primary productivity refers to the total capacity determined and the total amount of organic matter produced minus the amount consumed by vegetation respiration, which directly reflects the production capacity of vegetation communities under natural environmental conditions, characterizes the quality status of terrestrial ecosystems, and is calculated using the EC-LUE model developed based on vorticity related carbon flux site data. This dataset calculates the values of two indicators before and after the pilot implementation of the Sanjiangyuan National Park system (2016) (2010-2015 and 2016-2020), standardizes them, and finally merges them into the spatial distribution dataset of the ecosystem quality of Sanjiangyuan National Park.
