摘　　要：本研究通过实验观测数据 ,建立了用一般气象台站都具有的温度、湿度、蒸发、1 0cm土壤湿度等常规资料为信息输入的能较准确计算与TCK发生相关的土层 3cm相对湿度的数学模型。On the basis of experimental data,this research has established a mathematical modern which used some normal data as information input These normal data include temperature,humidity,evaporation and soil humidity of the 10cm depth,and commonly observatory often has these data This modern can be used to calculate relative humidity of the 3cm soil layer fairly and exactly,which has close connect with the state of TCK
