Research progresses of the author and their team on urban land-surface process and boundary layer structure was summarized in this paper. With the data analysis on urban boundary layer and satellite remote sensing, and the numerical study, the characteristics of the urban land-surface have been known, and the mechanism of urban boundary layer research was further carried out by building the fine urban boundary layer model system with the reasonable urban effect parameterization. The research results showed that: (1) The urban surface energy balance is very different from it on nature surface. (2) The satellite data with high resolution is an important approach to investigate the characteristics of urban surface parameter. (3) It is very important to introduce the anthropogenic heat parameterization into the model for accurately describing the urban surface energy balance. (4) The multi-layer urban canopy model has been developed for considering the buildings effect on the dynamical and thermal field of atmospheric motion. (5) The development of multi-scale urban boundary layer model system and the perfection of the urban effect parameterization in it made the simulation on local characteristic of urban boundary layer to be more reasonable. At present, with the speedup of the urbanization on various effects of the urban area expansion and layout on the change of weather/climate are very necessary.
