Abstract The climate changing characteristic and its effect on the eco-environment of HuLunHu Lake area in Inner Mongolia are studied by using the data of temperature, precipitation and remote sensing data from 1959 to 2005. The results show that: ①For the recent 46 years, the temperature rose notably in HuLunHu Lake area. The precipitation fluctuation was great and with periodicity changes of 11-year and 22-year; In general, precipitation had decreasing trend, especially since 1999. ②Either temperature or precipitation was in high climatic variability period for the recent 46 years, so the extreme climatic events increased. The eco-environment in HuLunHu Lake area tended to be degenerated since 1999 due to the climate warming and drying. Subsequently, a series of eco-environmental problem appeared, for example, the water area of HuLunHu Lake reduced, the wetland area shrank, and the grassland degenerated, and so on. ③Sprinkle event had decreased trend in recent years, but its intensity obviously increased after entering 21st century, so that the severe drought events obviously increased. The high frequency and high intensity of drought events had enhanced the deterioration of the eco-environment of HuLunHu Lake area.
