中文摘要	利用高精度的中国西部公元1 - 2000年温度和降水变化序列及CENTURY模型,重建公元1 - 2000年内蒙古荒漠草原、典型草原和草甸草原地上净初级生产力(ANPP)序列,利用小波分析探讨了不同草原生产力周期变化特征及与气候要素之间的相关性。结果表明: 1) 3类草原ANPP波动大体相似,其中在魏晋和明清小冰期出现明显低值期,在公元600 - 1200年出现长达600年左右的高值期; 2)不同草原ANPP波动有所不同,典型草原ANPP居中变幅最大,荒漠草原ANPP最低变幅次之,草甸草原最高且变幅最小; 3) 3类草原ANPP均存在准280a和准60a振荡周期,草甸草原ANPP还存在准150a振荡周期。4)降水和温度对草原ANPP有重大影响,但在不同类型的草原影响不同。典型草原和荒漠草原主要受降水控制,草甸草原受降水和温度共同控制。
英文摘要	The ANPP sequences of desert steppe,typical steppe and meadow steppe in Inner Mongolia were reconstructed by using the CENTURY model and high - precision sequences of changes in temperature and precipitation in West China from A. D 1 to 2000. The period features of ANPP for different steppes and their relationships with annual temperature and precipitation were investigated with the application of Pearson correlation analysis, continuous wavelet and cross - wavelet. The results indicate that: (1) The long - term fluctuations of ANPP for three types of steppe were generally similar. Significant low value period appeared during the Little Ice Age of Wei - Jin and Ming - Qing Dynasties,while high value period lasted for about 600 years from A. D 600 to 1200. (2) The fluctuation changes of ANPP for different steppes were different. The productivity of typical steppe was in the middle with the largest fluctuation range; desert steppe was the lowest with middle fluctuation range,and meadow steppe was the highest with the least fluctuation range. (3) The ANPP of these three types of steppe all had oscillation periods of around quasi - 280 years and quasi - 60 years. Meanwhile,a oscillation period of about quasi - 150 years existed in meadow steppe. (4) Precipitation and temperature had a significant effect on grassland ANPP,but in different types of grassland effects were different. The productivity of typical steppe and desert steppe were mainly determined by precipitation while for meadow steppe case,it was determined by the combined effects of precipitation and temperature.
