This paper divides eco-environmental loss into the loss of provisioning services, supporting services and regulating services. The loss of provisioning food and raw materials, soil conservation, species conservation, gas regulation, hydrological regulation is evaluated by the method of market value, opportunity cost, afforestation cost, shadow project, the sum of which is eco-environmental loss total value of debris flow disaster.
