Numerical solution of the model is maed by using Monte-Carlo sampling method.Its solution is astochastic field. It is showed by a real case that the model can describe the main trend and changing range ofpollutant'sconcentration at any calculating point,and the probability is added to the isopleth of the pollutant'sconcentration.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
