Abstract:

Land use/cover change (LUCC) will impact near the ground temperature measurement. Based on the temperature data from meteorological stations, 1:100000 LUCC data sets and NCEP reanalysis temperature data, we use"observation minus reanalysis (OMR)"method to extract the land cover individual contributions for temperature change. Also we use Sen trend method and Mann-Kendall nonparametric test to analyze the impact of air temperature and the change caused by LUCC. The result show that the air temperature generally exhibit significant warming trend during the study area in recent 30 years, the trend is 0.29 ℃/10 a. The order of different land cover type trend of temperature increase is sand land>built-up land> grassland>farmland. The temperature increase trend is different during different land cover types. Even the same land cover type could display different trends. The main LUCC change types are farmland reclamation, urban expansion and decrease in grassland area during the station buffer area between 1990-2005. To some extent, this result could reflects the whole LUCC change characteristics in the Inner Mongolia region, especially the anthropologic effects. LUCC caused the temperature increase 0.49 ℃ during 1990-2005. Between the 1980-2010, land cover changes gradually increased, especially after 2000, the rapid urbanization significantly increase the region temperature rising trend.

Key words: OMR, air temperature change, land use/cover change, Inner Mongolia Plateau
