Abstract

This study aims to analysis the characteristics of climate change on Hulunbeir steppe of China in the past 50 years which are from 1958 to 2007. Fist hand monitoring data were collected by utilizing a parametric model that is established using indicators of temperature, precipitation, and relative humidity. The Ivanov model were applied in the case study in order to calculate land evaporation and drought index for obtaining better understand on the climate changes in Hulunbeir Steppe. The modelling results indicated that the overall situation of climate change began to dry out and had a tendency towards drought according to the last 50 years, especially there was a significant increasing in average temperature, precipitation, and the evaporation. According to the monitoring date from our six meteorological stations established in Hulunbeir steppe, it has been shown that the average temperature have increased by 2.31 °C, the maximum value of precipitation have increased by 158.56mm after 1980s, drought indexes and evaporation capacity have increased by 3.2 to 10.6 times and 4.3 to 5.4 times during 1991 to 2007, respectively. The results in present study are expected to give a theoretical support for relevant researches in the future.
