The Ecological and Climatic Effects of Modern Oasis Evolution on the North Slope of Tianshan Mountains

Since the 1950s, the area of the oasis has increased around four times on the north slope of Tianshan Mountains, because of the large-scale water-soil development. However, the influences on the fragile ecosystems and regional climate caused by the process remain unclear. Therefore, to study the process, this project contains three aspects: field observation and data collection, model improvement and localization and model simulation. The carbon, water and energy fluxes are observed by the eddy covariance observation systems and Bowen Ratio equipment for model validation. The input climate datasets are collected from meteorological stations and reanalysis dataset. The other data such as land-use, land surface parameters and plant functional type data are collected from previous studies. The oasis management processes are coupled to the Arid Ecosystem Model (AEM), the land surface and several sensitive parameters are updated to localize the climate model ALARO and land surface model SURFEX. With the improved AEM model, the ecological effects of the modern oasis evolution will be simulated and quantified. The dynamics of the urban heat-island effect and the local circulation between oasis and desert will be simulated by using ALARO and SURFEX models.
