摘　　要：城市经济快速发展,重金属污染成为日益严重的问题。重金属传播近似满足高斯扩散模型,建立偏微分重金属污染物传播特征方程,基于非线性最小二乘法,结合L-M算法,求解出金属污染源位置。With the rapid development of urban economy,heavy metal pollution has become an increasingly serious problem.The propagation of heavy metals approximates to the Gauss diffusion model.The partial differential equation of heavy metal pollutant propagation characteristics is established.Based on the non-linear least squares method and L-M algorithm,the location of metal pollution sources is solved.

关 键 词：高斯扩散模型 非线性最小二乘法
