Other Abstract



The research on the biogeochemical cycles of nutrient elements and heavy metals on the Mt. Gongga was systemically reviewed,and the focuses and perspectives of future research were also prospected. The research of the biogeochemistry of carbon (C) and nitrogen ( N) in the ecosystem of Mt. Gongga was involved in their distribution characteristics,pools,and returning /release from litterfall through decomposition. The biogeochemical cycles of phosphorus ( P) have mainly explored the variations of its fractions and bioavailability along the altitudinal gradient and with soil development,and the migration and transformations of soil P as well as its controlling factors were
comprehensively deciphered. Moreover,the effects of microbial activity and  pedogenesis on the P bioavailability have been preliminarily explored. The distribution characteristics,sources and influencing factors of heavy metals on the eastern slope of Mt.Gongga have been systematically investigated in last few years according to multiple methods,and their contamination and potential ecological risks have also been assessed. In future,the systematic research on the biogeochemical processes and mechanisms of nutrient cycling need be delineated in the air-watersoil-
plant-microbial systems. Meanwhile,the processes of migration and transformation of heavy metals should be highlighted,and the key mechanisms controlling these processes need be further explored. A quantity of conceptual and numerical coupling models for the element cycles will be established to provide a theoretical basis for mountain ecological safety and ecological restoration.
