Using a regional climate model which was nested in a global climate model, the effects of industrialization on East Asian monsoon climate is simulated by employing the present-day vegetation or the preindustrial vegetation and corresponding CO2 concentration, and the changes in hydrology process, including vapor transportation, precipitation, evapotranspiration and runoff in eastern China during these periods are evaluated. Results indicate that industrialization leads to temperature rise in lots of regions, but the temperature changes are various for different areas. Temperature reveals marked rise in inner-Mongolia, northeastern China and northern China, while temperature fall exists in north of Sichuan. Industrialization also leads to drought climate in some areas of East Asian, especially in Huaihe valley, Shandong peninsula and Yunnan, but rainfall increase at middle reaches of Changjiang and Yellow River, and in Taiwan region. The changes of precipitation pattern induce more arid in the north of China, while aridity weakened at middle reaches of Yellow River, meanwhile, flood of Changjiang valley maybe reveals higher frequency.
