Regional ecological quality evaluation method and device

The invention discloses a regional ecological quality evaluation method and device, and the method comprises the steps: obtaining the index values of all evaluation indexes of a to-be-evaluated regionaccording to preset evaluation elements and evaluation indexes contained in the evaluation elements, wherein the evaluation elements comprise a water element, a gas element, a soil element, a biological element and a disaster element; standardizing the index values of the evaluation indexes to form dimensionless indexes; calculating an ecological environment comprehensive evaluation index value of the to-be-evaluated area; and according to a preset corresponding relationship between the ecological environment comprehensive evaluation index value and the ecological environment quality grade, outputting ecological environment quality grade of a to-be-evaluated region. The evaluation index system is established from the water, gas, soil, living and disaster perspectives, regional ecologicalquality evaluation is carr
