英文摘要Nitrogen (N) is an essential nutrient that is important for plant growth and productivity. How plants distribute N in different plant organs is aligned to the N use strategy of plants, and, in turn, provides an accurate way of assessing N storage in vegetation at the regional scale. Here, we analyzed variation in N concentrations across different organs and at different spatial scales. Specifically, we obtained 13,526 observations of plant N in China from consistent field measurements and from the published literature. The results showed that N concentration was significantly different across different plant organs (leaf, branch, trunk, and root), with more active organs having higher N. For forests, N concentration was ordered as: leaf (17.35 g kg(-1)) > root (6.66 g kg(-1)) > branch (6.47 g kg(-1)) > trunk (2.79 g kg(-1)). Similar trends were observed in grasslands, deserts, and wetlands. The N concentration of different plant organs significantly differed among different vegetation types [e.g., leaf N was ordered as: grassland (19.20 g kg(-1)) > desert (17.91 g kg(-1)) > forest (17.35 g kg(-1)) > wetland (14.58 g kg(-1))]. Furthermore, N concentration in different plant organs significantly differed across various regions. With increasing latitude and decreasing mean annual temperature, the N concentration of different plant organs increased, to some extent. Our findings provide new insights about the differences in the N use strategy of plants across plant organs and at different spatial scales. In conclusion, the data assimilated here provide a systematic reference point for estimating vegetation N storage at different scales.
