%X An Australia-China bilateral project on climate change has been developed to study impacts of land-use and land-surface processes on regional and global climate. This study presents results from a series of Australian Bureau of Meteorology Research Centre (BMRC) climate model simulations of land-use in China on regional climate and Australia-Asian monsoon system. Six pairs of 54-yr BMRC model integrations using multi land-surface configurations allow us to explore the degree of uncertainty in the model land-use simulations caused by land-surface modelling itself. The climate impacts of land-use are assessed by applying two sets of surface vegetation datasets in the model: one represents current vegetation coverage in China and the other approximates its potential vegetation coverage without human intervention. The imposed surface parameter changes include changes in surface albedo, surface roughness, vegetation fraction and leaf-area-index (LAI). Ten model ensemble simulations have been conducted to allow us to compare the model-simulated land-use signal to its intrinsic variability. Results from additional model experiments will be analysed to compare the impacts of land-use forcing to CO2 increases and SST variations in explaining the observed climate variations in the region in the last century.
