Based on the synthetic panel data of the incidence of soil erosion area and the impoverishment rate in Chinese provinces domains,through the establishment of economic model and quantitative analysi.

The result showed water and soil loss rate and water loss rate to be better indicators for the assessment of water and soil loss in urban forest.

According to the evaluation indexes system frame established on improvement rate of soil and water loss,health diagnoses of several typical regions from soil and water loss improvement are comprehensively evaluated.

This paper establishes a comprehensive evaluation index system frame of improvement rate of soil and water loss by adopting survey data of soil and water loss in several typical regions from water and soil resources,ecological environment and economic development.

The purpose of the study was to construct a system dynamics model of soil and water loss on slope surface on the basis of system dynamics principles through the analyses of soil and water loss processes and its influencing factors.
