Since January 2000, He has been working as a leading professor at Institute of Geographical Sciences and Natural Resources Research, Chinese Academy of Sciences. He has innovatively been developing methods for high accuracy surface modelling (HASM) to give solutions to error problem, slow-computational-speed problem and multi-resolution problem which long troubled surface modelling. HASM has been successfully applied to simulating surfaces of elevation, soil properties, changes of biodiversity and ecosystem services, and driving forces of the changes as well as analysing ecosystem responses to climatic change. In all these applications, HASM produced more accurate results than the classical methods. In 2016, a Fundamental Theorem of Earth Surface Modelling (FTESM) is abstracted on the basis of all the applications of HASM in last 25 years. From FTESM, seven corollaries have been deduced, corresponding to interpolation, upscaling, downscaling, data fusion and model-data assimilation respectively.
