|on the physical mechanism of wind erosion and dust emission，the advances on dust storms in China were reviewed
from the micrometeorological perspective，the characteristics of micrometeorological variables and the evolutional discipline of turbulent
fluxes during dust events as well as atmospheric turbulence effect on parameterization of dust storms were introduced． Meanwhile，combining
with relevant research abroad，shortness at present and research direction in the future about dust events research were discussed，
including taking different turbulence parameterization schemes in dust storms modeling and comparing the results with the field
and satellite observations; obtaining the high quality profiles of meteorological variables in the surface layer during dust events; studying
the influences of soil moisture on dust emission thresholds over various dust sources; measuring and modeling dust emission rates
of different soil particle size bins and dust flux profiles．

According to the climate data (1953 - 2006) in the farming - pasturing interlocked area of InnerMongolia (Duolun) , the response of local grassland p roductivity to the climate change is analyzed. Climate models (Miami and ThornthwaiteMemorial) are introduced to evaluate the grassland potential p roductivity. It is showed that ThornthwaiteMemorialmodel could better describe the main features of the grassland potential p roductivity change with climate factors in Duolun County, and both temperature and p recip itation increase could enhance the potential p roductivity, but p recip itation is the key climatic factor limiting the potential p roductivity. The grassland actual p roductivity observed in Duolun County is then compared with the effective potential p roductivity. The results show that the p roductivity level of natural grassland is very low (412 kg/hm² ·a) , which is only 26% of its effective potential p roductivity, and there is a large room for imp roving. Both of the potential and actual p roductivities of the artificial grassland are much higher than those of the natural grassland, which indicates that the development of artificial grassland could be highly efficient for imp roving the local
grassland p roductivity. The actual stocking rate in 2000 - 2002 is also compared with the estimated theoretical one, and an average overloading rate up to 79. 3% exists in this period.
