Chinese scientists mapped non-photosynthetic vegetation across China, finding it covers 37% of land and growing, with implications for carbon cycling and climate resilience.
Chinese scientists at Nanjing University created a high-precision remote sensing method to map non-photosynthetic vegetation (NPV) across China from 2016 to 2024 at 300-meter resolution.
The study found NPV covers about 37% of China’s land area on average, increasing by 0.14% annually, with the fastest growth in semi-arid to semi-humid regions at 0.75% per year.
Seasonal temperature and precipitation drive NPV changes, and a new spectral detection method in the 750–900 nanometer range improved accuracy.
The research introduces a carbon exchange flux index, highlighting NPV’s role in carbon cycling and soil sequestration, addressing long-standing challenges in large-scale carbon monitoring and offering insights into ecosystem resilience and climate feedbacks.
