甘肃气候生产力格局及演变
Spatial pattern and regional response of climate-productivity over Gansu area
【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。
【Abstract】 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.
