摘要
采用灰色关联分析法,对海西州牧草产量与主要气象因子6~8月平均气温、6~8月平均降雨量的关联度进行了分析。结果表明:海西州牧草产量与主要气象因子关联顺序依次为:6~8月平均降水量>7月降水量>6月降水量>8月降水量>6月平均气温>6~8月平均气温>7月平均气温>8月平均气温,海西州牧草产量与6~8月平均降水量的关联度最高。因此,海西州牧草产量对降水量敏感度高于对气温的敏感度,降水量是影响海西州牧草产量的主要因子,气温基本满足牧草生长需求。
Using the gray correlation analysis method,the correlation degree between the forage yield prefecture and the main meteorological factors,including the monthly mean temperature and monthly precipitation in Haixi,was analyzed.The results showed that the order of correlation between the forage yield and the main meteorological factors in Haixi Prefecture was as follows:the total precipitation from June to August>precipitation in July>precipitation in June>precipitation in August>monthly mean temperature in June>monthly mean temperature from June to August>monthly mean temperature in July>monthly mean temperature in August.Therefore,the sensitivity of forage yield in Haixi Prefecture to precipitation is higher than that to temperature,precipitation is the main factor affecting forage yield in Haixi Prefecture,the temperature basically meets the needs of forage grow.
