- Abstract:
- In order to further improve the plant nutrient cycle model in China, we used meta-analyses to collect 51 published studies to explore the different N/P resorption pattern between herbs, shrubs and trees and the relationships between N/P resorption, temperature and precipitation in China. The results showed that:(1)average N contents of senesced leaves in herbs, shrubs and trees were 9.05 mg/g, 14.91 mg/g, 12.72 mg/g, respectively; average P contents of senesced leaves of herbs, shrubs and trees were 0.50 mg/g, 0.79 mg/g, 0.76 mg/g, respectively; average N resorption efficiencies of herbs, shrubs and trees were 64.16%, 51.97% and 35.82%, respectively; average P resorption efficiencies of herbs, shrubs and trees were 65.51%, 46.74% and 41.72%, respectively;(2)N and P contents of senesced leaves of herbs were significantly lower than those of shrubs and trees; N and P resorption efficiencies of herbs were significantly higher than those of shrubs and trees; N resorption efficiency of shrubs was significantly higher than that of trees; There was not remarkable difference to other variables of nutrient resorption between shrubs and trees;(3)N and P contents of senesced leaves were positively correlated with temperature; there was a negative relationship between N resorption efficiency and temperature, while P resorption efficiency was not related to temperature; N content of senesced leaves and N resorption efficiency were positively and negatively correlated with precipitation, respectively; there was no correlation between P content of senesced, P resorption efficiency and precipitation; this result indicated that the high nutrient resorption efficiency of herbs might reflect that the regeneration rate of herbs was higher than that of shrubs and trees; it also indicated that different life-form plants had various nutrient adaptation strategies to the environment shifts. In this study, N resorption was more sensitive to the changes of precipitation and temperature than P resorption. It suggested that the strategy of plant N uptake and utilization might be more flexible than that of P along the climate gradients. The response of N and P resorption pattern to temperature and precipitation may imply the difference adaptability of plant to hydrothermal conditions under the climate change.
