Q (Qiannan) Leng

I am a visiting PhD student from the University of Chinese Academy of Sciences (UCAS), and I am very pleased to have the opportunity to come to the FEM group to carry out a 7-month study. I mainly focus on the impact of climate change on the productivity of plantation trees and their coupled water-carbon physiological mechanisms. Through the combination of tree-ring analysis and measurement of functional traits related to water-carbon physiology, the main afforestation tree species in Saihanba, China (Larix principis-rupprechtii and Pinus sylvestris var. mongolica) are used as research objects to explore 1) the main factors affecting tree productivity and their physiological and ecological mechanisms in water-limited habitats, and 2) the intrinsic water-carbon physiological mechanisms of the effects of stand density on tree productivity. The aim is to provide a theoretical basis for improving the functional stability of forests in water-limited areas and to provide a reference for the prevention the decline of silvicultural species in certain areas, as well as for the rational management and administration of forests.
