摘　　要：通过对1971-2000年天水气候及林业产值变化分析,得出影响天水市国有林区林业产值的主要气象条件是4-8月降水量和≥0℃积温;建立了天水林业气候产值的数学模型,得出了适宜天水林业生长的水热匹配规律,水热匹配指标为R年≥0.12∑T年≥0℃。Changes on climate and output value of forestry production in Tianshui City from 1971 to 2000 were analyzed. It is concluded that main meteorological conditions, which influenced changes of output value of forestry production, were monthly average precipitation and accumulated temperature above 0℃ during April and August. The mathematical model on climate influenced output value of forestry production was established. The water-thermal matching index, which indicated the suitable degree for tree growth, was obtained.
