摘要
本文根据年降蒸差和干旱季节0～50cm 土层贮水量等指标,运用均值聚类方法将宁夏划分出4个土壤水分区,并对各区进行了评述。试用结构函数确定测站布局。对川区和山区土壤湿度观测时间提出了建议。
According to the indexes of diffrernce between precipitation and potential evapotranspiration and of moisture content in 0～50 cm soil layer in dry season,using the method of average value cluster,the Ningxia Province is divided into four soil moisture divisions Each division is described.The stations distribution is difined using structure function The suggestion on measuring time of soil moisture in plain and mountain area is made.
