Abstract

The paper takes Chenbarag Banner, Hulunbuir on as the research object, analysis the meteorological data of 1980-2015 and quadrat survey data of 2011-2015, preliminary mastered the influnce of climate change on clipping pasture's straw yield in Hulunbuir Grassland. It is concluded that: First, Chenbarag banner, Hulunbuir's the average temperature increased 1.43 or so in past 35 years ,and average rainfall fell 40.4mm,and sunshine durationÿreduced about 79h.he trend of warming in summer is the most significant, spring and autumn season are secondly, and does not significantly in winter. The trend of precipitation in summer is most significant, followed by autumn, winter and spring have slightly increasing trend instead,and winter obvious than spring. The trend of sunshine duration is reduced obviously in grass growing season.Second, by analyzing the correlation between climate change and clipping pasture's straw yield, it is concluded that there are highly positive correlation between precipitation and straw yield, and precipitation is one of the most factors to affect local clipping pasture's straw yield. Finally, according to the local climate trend's characteristics and clipping pasture's straw yield's correlational relationship with rainfall , predicted the trend of clipping pasture's straw yield in the next 50 years.
