青藏高原氮沉降研究现状及草地生态系统响应研究进展
Research progress on nitrogen deposition and grassland ecosystem response in Qinghai-Tibet Plateau
摘要
Abstract
In order to understand the characteristics of nitrogen deposition in the Qinghai-Tibet Plateau,references on atmospheric nitrogen deposition and its effect on the plateau ecosystem under the background of rapid economic development in Tibet region are reviewed.The results of previous atmospheric nitrogen deposition monitoring study in different areas of the Qinghai-Tibet Plateau are summarized.The effects of atmospheric nitrogen deposition on grassland ecosystems are summarized and compared.The results show that:The quantitative analysis of nitrogen deposition fluxes in the Qinghai-Tibet Plateau are relatively less,which are limited to short-term monitoring or only quantitative precipitation nitrogen content.Long-term situ monitoring,atmospheric reactive nitrogen composition characteristics, urban-rural differences and trends are still unknown;Plant diversity,plant stoichiometry and phenology under enhanced atmospheric nitrogen deposition in Qinghai-Tibet Plateau grassland are still unclear,especially the mechanism is ambiguous.Nitrogen deposition,as one of the main driving factors of global change,and its impact on the ecological environment in the Qinghai-Tibet Plateau needs to be further investigated.关键词
