Preliminary analysis of Long-term hydro-meteorological, ecological and dendro-chronological monitoring over the larch forests on the permafrost in northern Mongolia

Abstract

To clarify the heat, water carbon exchange process and dynamics by comprehensive approach, we started long term monitoring of the eddy-correlation based flux observations, the hydro-climatic observations, the phonological camera monitoring and sap flow measurement at the 25-m height tower and forest around the tower in the Udleg (48 15’43.7” N, 106 50’56.6”E, altitude: 1264m) over the larch forest in Research Forest of NUM in northern Mongolia since 2009. We’ve also carried out the tree-ring observation to get the stand history (age, growth rate, fire, drought etc.) and dendrometer observation to get the diameter growth of larch trees.
