The identification and assessment method of environmental damage of an ecological damage event
With the aggravation of the contradiction between the rapid growth of socio-economic and human needs and the ecological carrying capacity,the structure and function of typical ecosystems are degraded and ecological environment damage events occur frequently.This paper takes an ecolog-ical damage event in Shandong Province as an example,and discusses the ecological damage investi-gation,damage confirmation,causality analysis,damage physical quantification,restoration program development and damage value quantification in the ecosystem damage appraisal,and constructs a set of appraisal methods for the ecosystem environmental damage by agricultural excavation.The method was used to quantify the ecological damage caused by the incident in terms of damage during the peri-od of ecological service functions and ecological restoration costs.
