摘　　要：为揭示甘肃气候生产力的区域响应特征,利用甘肃省分布比较均匀的64站50a(1957-2006年)实测气象资料,研究该区域气候生产力格局和时空演变。结果表明:甘肃气候生产力对气候响应的空间一致性程度低,形成河西走廊、中北部区、甘南陇南山区次区域一致空间格局;中北部区是甘肃响应最敏感的地方,河西走廊次之,甘南陇南山区最低;河西走廊以气候生产力低、相对变幅大,年代际振荡弱、生产力增加为主要响应特点,甘肃地区气候生产力较高、年际振荡强、年代际振荡明显、生产力不断下降,甘南陇南山区气候生产力变幅小、振荡周期复杂。To reveal the productivity of the regional response to climate characteristics in Gansu,data of 64 stations of 50a（1957-2006） were used to study the regional climate patterns and spatial and temporal evolution of productivity.The results showed that：Gansu climate productivity to climate showed the low level of spatial coherence,the spatial patterns of the Hexi Corridor,north-central area,Gannan Longnan mountainous sub-region were basicily same;north-central area is the most sensitive areas in Gansu;Hexi Corridor is the second,Gannan Longnan Mountain is the minimum;Hexi Corridor＇s weather productivity is low,and has relatively large amplitude,and interdecadal oscillation is weak.Regional climate productivity of Gansu is higher,inter-annual oscillation is strong and decadal oscillation is obvious and productivity is declining.Gannan Longnan mountain climate productivity is of small amplitude oscillation cycle and complex.
