摘要
利用阿鲁科尔沁旗生态监测站2005-2014年年平均气温、年降水量、牧草监测数据,分析了天然牧草生长及产量与气象条件的关系。结果表明:阿鲁科尔沁旗年降水量与牧草产量呈极显著正相关(P<0.01),相关系数为0.775,直接通径系数为0.788,直接效应最为明显,年均气温与牧草产量呈不显著正相关关系。因此,年降水量是影响阿鲁科尔沁旗天然牧草产量最主要的因子。
By using th e observed data related to grass growth and meteorological conditions during ten continual growing seasons from 2005 to 2014 in Arhorchin Banner, the relationship between hay yield of natural and meteorological conditions were comprehensively studied and analyzed. The results showed that the annual precipitation significantly correlated with hay yield with the simple correlation coeffocients was 0.775,the direct path coefficients was 0.788 in Arhorchin Banner, whereas the annual average temperaturedid not significantly correlated with hay yield, which implied annual precipitation was the most important factor in determining hay yield. Therefore, the main meteorological factors to influence the forage growth and yield in this area were short of precipitation.
