【Abstract】 The research on mechanism of soil nutrient loss by erosion and land covering pattern succession has been regarded mostly as a base research content of the globe change,and the reciprocity of matter and energy between the terrene and atmosphere,which will produce a new research subject with integration and interconnection crossover.The essentiality of this research,the relationship of soil nutrient loss mechanism by erosion and land covering pattern succession,the model of soil nutrient loss by erosion in little catchment and future research expectation in this research were illustrated for promoting the soil environment science to develop.更多还原
