Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Carbon, nitrogen and phosphorus are important elements in biogeochemical cycles, they play an important role in the ecosystem, the study about the ecological stoichiometry for C, N and P in the plant leaves is a hot topic of ecological field. The characteristics of ecological stoichiometry are explored by studying the content of C, N and P in the leaves of Leymus chinense at different succession stages of grassland degradation from the Jiangjiadian grassland in Da´an city in western Jilin Province. The results show that the maximum C content appears in lightly degraded grassland, and the minimum C content appears in the very seriously degraded grassland. However, the maximum N content appears in the very seriously degraded grassland, and the minimum N content appears in the undegraded grassland. The maximum P content appears in the very seriously degraded grassland, and the minimum P content appears in the moderate degraded grassland. The maximum value of C: N appears in the undegraded grassland, the minimum value of C: N appears in the very seriously degraded grassland. The maximum value of C: P appears in the moderate degraded grassland, the minimum value of C: P appears in the undegraded grassland. The maximum value of N: P appears in the seriously degraded grassland, the minimum value of N: P appears in the undegraded grassland. The undegraded grassland is limited by both N and P; the degraded grassland is limited by P. The ecological stoichiometry characteristic provide useful guidance on different degradat- on succession Stages.
