Outline of Final Research Achievements

Desert ecosystems have very specific water cycles compared with other ecosystems. The target of current research is in premier to reveal the response of desert ecosystems in Central Asia to environmental changes from the perspective of ecohydrology on the basis of multi-scale ET monitoring and modelling. Furthermore, the research also aims for setting up an early stress-detecting system for this fragile ecosystem based on remote sensing technique. Annually continuous monitoring of leaf, branch, canopy and plot scale ET in desert ecosystem revealed that this type of ecosystem had very low water being transpired during growth periods. Vulnerability assessment of the ecosystem has been based on CLM using different RCP scenarios. Furthermore, effective remote sensing indices have been identified for tracing different scale transpiration and thus provide a base for building up early stress-detecting system.
