摘　　要：利用格尔木3个国家气象站1991~2021年气象要素和枸杞发育期资料,计算近31 a来枸杞气候适宜度,分析其生育期变化特征。结果表明:枸杞各生育期气温适宜度在0.181~0.838之间,前期年际波动较小,中期波动较大;降水适宜度在0.100~0.765之间,年际波动较大;日照适宜度在0.600~0.990之间,年际波动较小;综合气候适宜度在0.436~0.745之间,年际波动较小。全生育期气温适宜度和降水适宜度均呈波动增加趋势,而日照适宜度呈波动减少趋势。从空间分布来看,格尔木气温适宜度最大,诺木洪次之,小灶火最小;诺木洪降水适宜度最大,格尔木次之,小灶火最小;小灶火日照适宜度较好,格尔木次之,诺木洪较差。整体来看格尔木种植区气候适宜度较好,适合枸杞种植。The climate suitability of Lycium barbarum in recent 31a was calculated by using the meteorological elements and the data of Lycium barbarum development period from 1991 to 2021 from 3 national meteorological stations in Golmud,and the variation characteristics of Lycium barbarum growth period were analyzed.The results showed that the suitability of temperature conditions in each growth stage of Lycium barbarum ranged from 0.181 to 0.838,and the inter-annual fluctuation was small in the early stage and large in the middle stage.The precipitation suitability ranges from 0.100 to 0.765,which fluctuates greatly from year to year.Sunshine suitability ranges from 0.600 to 0.990,with little inter-year fluctuation.The suitability of comprehensive climatic conditions is between 0.436 and 0.745,and the inter-annual fluctuation is small.During the whole growth period,the temperature suitability showed an increasing trend and the precipitation suitability showed a slightly increasing trend.Sunshine suitability showed a slightly decreasing trend.From the perspective of spatial distribution,Golmud planting area had the largest temperature suitability,followed by Nuomuhong,and small stove fire was the smallest.The suitability of precipitation in Nomuhong planting area was the highest,followed by Golmud,and small stove fire was the lowest.The sunshine suitability of small stove growing area is better,Golmud is second,and Nuomuhong is poor.Overall,the climate suitability of Golmud planting area is good,which is suitable for wolfberry planting.
