| 摘 要： | 利用湖北省76个气象台站1960～2005年逐年年平均气温、降水资料，应用Miami模型、Thomthwaite Memorial模型对湖北省气温气候生产力（TSPt）、降水气候生产力（TSPn）和蒸散量气候生产力（TSPv）进行了估算，并采用EOF、RE．OF、EEOF、Mann—Kendall检验、小波分析等方法研究了湖北省TSPv的演变及其对气候变化的响应。结果表明：降水是大部分地区作物产量的限制因素；TSPv在时间上波动明显，在空间上受地形、降水、人类活动等因素影响，西部山地区震荡特征明显，东部平原丘陵区具有稳定的上升趋势，西北山地区是震荡的敏感区；未来“暖湿型”气候对作物生长最有利，“冷干型”气候对作物生长最不利，北部地区是气候变化的敏感区。图4，表2，参11。 |

| Abstract: | Based on the data of annual average temperature and annual precipitation of 76 meteorological stations from 1960 to 2005 in Hubeiprovince,the temperature climate productivity potential (TSPt),the precipitation climate productivity potential (TSPn) and the evapotranspi-ration climate productivity potential (TSPv) in Hubei province were evaluated by Miami Model and Thornthwaite Memorial Model. EOF, REOF,EEOF, Mann-Kendall Test, Wavelet-based Analysis were used to analyze the evolvement and effects of climate-productivity on climate change in Hubei province. The results showed that rainfall was the restrictive factor of TSPv in most areas. There existed significant fluctuations of TSPv as time changes.Topography, rainfall, human activities and other factors influenced TSPv changes in space.The western mountain region was char-acterized with obvious oscillation and the eastern plains and hills were characterized with stable upward trend, and the mountain region in north-west Hubei was the sensitive area to TSPv oscillation.The future "warm-wet" climate was beneficial to crop productivity,while "cold-dry" cli-mate can lead to decreases in TSPv. North Hubei is the sensitive region to global climate change. |
