Key points in enacting provincial soil erosion and water loss crisis emergency response plan

No matter the irregular sudden bursting high-intensity soil erosion and water loss crisis incidents, or the regular continuing cumulative soil erosion and water loss crisis incidents, may make great negative impact and threat to both people's production and their living, even to their lives. Compiling and enacting emergency response plan of soil erosion and water loss crisis incident at all levels are effective in achieving reasonable response to prevent and handle soil erosion and water loss crisis incident. Among them, the provincial soil erosion and water loss crisis incident emergency response plan is the representative one and so that it is studied in this paper respectively. In its enacting, the matter about how to distinguish the different types of crisis incident in order that prevention and treatment work can be put into effective use respectively, and the determination of different grade plan starting standards and the classification criterion of soil erosion and water loss crisis incident in order that suitable forecasting, warning and emergency response can be achieved, are the most important and difficult problems. In this paper, the categories of soil erosion and water loss crisis incident is classified as normal soil erosion and water loss crisis incident and abnormal one according to the rapid occurrence degree, scale and scope of erosion and water loss crisis incident, and the need of fathering and treatment after analysis and study. Also, the classification criterion of soil erosion and water loss crisis incident and the starting standard of emergency plan at all levels are put forward due to the indexes of soil erosion intensity, erosion degree, types and numbers of crises, disaster impact scale and extent. The research work in this paper make a good foundation for the final determination of soil erosion and water loss crisis incident emergency response plan at all levels.
