摘要
对辉腾锡勒草原15年间多个气象因子和风机数量之间的相关性进行了研究,结果表明:风机数量的增加与NDVI指数具有正相关关系,会导致研究区地温和蒸发量升高,空气相对湿度降低,但是对降水量的影响不大。地温的增加有利于植物的生长,同时蒸发量的升高和空气相对湿度的降低表明风机数量的增加有导致研究区域干旱程度加重的趋势。
For the correlation between the number of meteorological factors and the number of fans in the research area during the 15 years,the research analysis has concluded that the increase in the number of fans has a certain positive correlation with the NDVI index,which will lead to an increase in the mild evaporation in the research area and a decrease in the relative humidity of the air.However,the influence on precipitation is not large,and the increase of ground temperature is conducive to the growth of plants.At the same time,the increase of evaporation and the decrease of air relative humidity indicate that the increase in the number of fans has led to a tendency towards drought.
