Abstract:The objective of this study was to clarify the ecological stoichiometry characteristics of leaves and litter in different plant communities in the Yongli colliery reclamation area. Leaves and litter were collected, and organic carbon (C), total nitrogen (N), total phosphorous (P), and total potassium (K) content were measured.Plant nutrient values and restriction factors for the reclamation area were determined and nutrient cycling between leaves and litter was investigated. The results indicated that: (1) There were significant differences in leaf C content among the different plant types. C content was the highest in shrubs (Platycladus orientalis (L.) Franco, 537.96 g/kg) and the lowest in herbs (Astragalus adsurgens Pall., 423.73 g/kg). Leaf N, P, and K content did not differ significantly between plant types. In contrast, there were significant differences between plant types for the N and P content of the litter. C content was significantly higher in Hippophae rhamnoides Linn. (417.84 g/kg) than in A. adsurgens and Caragana korshinskii Kom. N content was the highest in A. adsurgens (20.30 g/kg) and the lowest in C. korshinskii, whereas P content was the highest in A. adsurgens (1.57 g/kg) and the lowest in H. rhamnoides. K content was significantly higher in A. adsurgens (6.31 g/kg) than in H. rhamnoides and C. korshinskii. C, N, P, and K content were higher in the leaves than in the litter. The resorption efficiencies of N, P, and K was in the range of 5.17-50.16%, 4.19-6.41%, and 11.27-23.24%, respectively. N resorption was significantly higher in H. rhamnoides than in C. korshinskii and A. adsurgens, P resorption was the highest in A. adsurgens and the lowest in C. korshinskii, and K resorption was the highest in H. rhamnoides (23.24%) and the lowest in C. korshinskii; and (2) Shrubs and herbs had an N/P ratio > 16. This finding indicates that the growth of these plants was primarily limited by P. In contrast, macrophanerophytes had an N/P ratio < 14, which indicates that growth was primarily limited by N. Combined with C, N, and P content in the soil, leguminous plants should be planted in the early stage of vegetation restoration, followed by shrubs or macrophanerophytes.
