The merits of Thomas Ford Brown's definition are:(1) Systemism implies a three-dimensional analysis that integrates well the individual egos in a network with the network structure, taking into considerations each proactive egos as well as the characteristics and influence of the whole network;(2) He emphasized that this is a processual system that indicates the interactive relations between components, structure and environment, giving the system a dynamic feature.

During the establishment of sediment yield dynamic model at the watershed outlet, it was difficult for us to carry out dynamic monitoring of each impact factors in the whole basin, because it was a long time research and was in very large-scale watershed. Taking into account the interannual variability of sediment yield mainly affected by hydrological conditions of rainfall - runoff and underlaying surface changes caused by soil conservation measures, a combined influence factor which is related to surface runoff modulus and the implementation time of the water and soil conservation project was proposed for the first time. Furthermore, its specific expression was determined through dimensional analysis and non-linear regression multianalysis.
