Abstract:According to the principle and method of population system control,ecological control system of main pests in leaf vegetables was established,and its practical effect on the produce was evaluated by the method of environmental economics,which was also compared with those under chemical control.Results showed that the economic,social and environmental benefit was greatly improved afted the utilization of ecological control system.
Keywords:pest ecological control system  biological control  environmental economics analysis
