A dataset of leave nitrogen to phosphorus ratios in China’s shrubland ecosystems with a resolution of 1 km

<p indent="0mm"> The leaf nitrogen to phosphorus ratio (N:P) is an important indicator describing plant nutrition limitation. Large-scale N:P data plays an essential role in assessing nutrition utilization in ecosystems and estimating the carbon sink potential under nitrogen and phosphorus deposition. However, ecosystems are highly influenced by human activities, leading to greater uncertainty in their study. This dataset establishes relationships between ground-measured data and environmental factors using a machine learning algorithm, generating a d dataset of leave nitrogen to phosphorus ratios in China’s shrubland ecosystems with a resolution of <sc>1 km,</sc> with each grid cell representing the estimated leaf N:P ratio, and is available in TIFF format. The testing results and comparison with other similar data both demonstrates the high accuracy of the dataset. This dataset objectively reflects nutrition limitation in shrubland vegetation, and can be used for studies on nutrient utilization and carbon sink potential in shrubland ecosystem.
