高斯扩散衍生公式在环境风险评价中的应用

为在大气环境风险评价中客观地确定危险源、估算各类突发性事故的危害，在高斯扩散模型基础上，通过严格的数学推导，得出一整套适用于鉴别与评估大气环境突发事故危害后果（危害区、危害期等）的定量估算公式，使用方便，结果精确。所有公式使用条件与高斯扩散模型相同，可用于直接求取任意浓度等值线精确的时、空位置及其特征点位置。作为高斯扩散模型的衍生公式，可广泛应用于风险工程设计、风险工程保险、环境风险评价、环境风险管理、环境影响评价与环境规划等各个领域

The application of extended Gaussian diffusion formulae on environmental risk assessment.

To identify hazard sources objectively and evaluate hazard of various accidents on atmospheric environmental risk assessment,based on Gaussian diffusion model and rigid mathematics,a modeling system was developed to identify harm and estimate impaired region of accident and impaired duration of accident in atmospheric environment.These formulae are easy to use with exact results.This modeling system has the same conditions as Gaussian diffusion model,and can calculate any concentration isoline's rigor time space location and specific points location. As the extened formulae of Gaussian diffusion model,it can be applied broadly for risk engineering design,risk engineering insurance,environmental risk assessment,environmental risk management,environmental impact assessment,environmental planning.
