摘  要：
利用柴达木盆地11个气象台(站)1991～2017年气温、降水量、日照和枸杞产量、种植面积等资料,应用数理统计方法,分析了该区近27a来气温、降水、日照及枸杞产量、面积的变化特征,并分析了气候因子对枸杞产量、面积的影响。27a来柴达木盆地年平均气温升高显著,升温率为0.5℃·10a~(-1);降水呈略增加趋势,增幅为16.5mm·10a~(-1);日照时数呈减少趋势,减少倾向率为71.6h·10a~(-1)。柴达木盆地枸杞产量和面积呈明显增加趋势,每10年枸杞产量和面积分别增加331.7kg·hm~(-2)、12250.4hm~2;枸杞产量和种植面积与气温、降水量呈正相关关系,与日照时数呈负相关关系,气温升高、降水量增加、日照时数略减少对枸杞产量提高和面积增加有利。

摘  要：
Based on the data of temperature,precipitation,sunshine,crop yield and planting area of Lycium from 11 meteorological stations in Chaidamu Basin from 1991 to 2017,the mathematical statistics method was used to analyze the temperature,precipitation,crop yield of Lycium,the changes of temperature,precipitation,Sunshine and the yield and area of Lycium in recent 27 years were analyzed,and the effects of climate factors on the yield and area of Lycium were analyzed.The annual mean temperature increased significantly,with the warming rate 0.5℃·10 a~(-1),the precipitation slightly increased by 16.5 mm·10 a~(-1),and the sunshine decreased by 71.6 h·10 a~(-1).The yield and area of Lycium in Chaidamu Basin increased by 331.7 kg·hm~(-2) and 12250.4 hm~2 every 10 years;The yield and acreage were positively correlated with air temperature and precipitation,and negatively correlated with sunshine,the increase of temperature,precipitation and sunshine hours were beneficial to the increase of yield and area of Lycium.
