中文摘要	感热和潜热的估算在陆气、海气相互作用的研究中具有重要意义;波恩比法是估算感热和潜热的重要方法,它以其低廉、简单和无需知道近地层动力特征的特点而被普遍使用。利用黄土高原陆面过程试验(LOPEX)的观测资料,研究了半干旱区热量在土壤中传递的慢过程对波恩比法估算感热和潜热的影响。结果发现,反映慢过程的传输线法和四边形法比不考虑慢过程的常规法在波恩比法估算感热和潜热的精度方面有一定提高,而反映慢过程的三角形法估算精度低于常规法,究其原因是三角形法计算复杂所致。所以,扣除计算中的不确定因素,考虑慢过程在一定程度上可以提高半干旱区波恩比法的估算精度。
英文摘要	The estimation of sensible heat and latent heat is important in interaction between land and atmosphere, and sea and atmosphere. Bowen ratio method is an important method in estimating sensible heat and latent heat, and it has been widely used for its characteristics of cheap ,simple and unnecessary to know surface layer dynamic process. The effect of the slow transport process(STP) existing in soil heat transport in semi-arid area on estimation of sensible heat and latent heat by Bowen ratio method was studied based on land surface process observational data collected in Dingxi Base of Lanzhou Institute of Arid Meteorology. The results showed that the transport line approach in slow transport process on estimating sensible heat and latent heat by Bowen ration method was more highly accurate than quadrilateral approach without slow transport process. While the triangle approach in slow transport process was less accurate than traditional approach, though it could also reflect the STP. The reason was that it would cause the complicated calculating. So, if neglecting the factor of complicated calculation of triangle approach, the STP could improve the accuracy of estimating sensible heat and latent heat by Bowen ratio method to some degree in semi-arid area.
