摘　　要：应用灰色关联度方法,对鄂尔多斯市乌审旗乌审召镇滩地草场1985-2005年天然草地产量与各年3-7月份降雨量、温度、相对湿度、日照时数的关联度进行分析,以探讨气候因子对草地生产力的影响,为草地合理管理和持续利用提供理论支持。结果表明:降雨量和温度与草产量的关联度高,是影响该地区天然草地产量的主要生态因子;其中3月份降雨量与草地产量的关联度最高;5、6、7月份在降雨量和温度均较好的情况下,日照时数是影响草地产量的主要生态因子。In order to explore the effect of climatic factors on grassland yield and provide theoretical support for rational management and sustainable utilization of grassland,the correlation between grassland yield and monthly climatic factors including rainfall,sunshine hour,average temperature,and relative humidity was analyzed using grey correlation analysis for grassland in Wushengzhao Town,Erdos,Inner Mongolia Autonomous Region from March to July during 1985 to 2005.Results show that the grassland yield had highest correlation degree with temperature and rainfall amount and temperature and rainfall amount were the main ecology factors influencing grassland yield.The correlation degree between rainfall and yield was highest in March,while sunshine hour was the main ecology factor affecting grassland yield from May to July when preferable rainfall and temperature conditions were available.
