Embodiment Construction
[0040] The ecological risk assessment method of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0041] Such as Figure 1 to Figure 2 Shown, described ecological risk assessment method comprises the following steps:
[0042] Step 1. Ecological risk source identification and quantitative sub-technology construction, comprehensive material-value input-output model and structural decomposition analysis, and realize the identification of ecological risk sources by accounting for ecological risk source identification indicators reflecting industrialization and urbanization:
[0043] Step 1.1, based on the material-value input-output model to calculate the accumulated resource consumption / pollutant discharge of the industrial chain, expressed by the following formula (1):
[0044] f=F(I-A) -1 y=FLy...(1);
[0045] In the formula: f represents the resource consumption / pollutant disc...
