The first step in carrying out environmental quality monitoring is to formulate a monitoring plan and to obtain accurate information on the environmental quality from the monitoring results. It is more important than the advanced level of the agricultural environmental monitoring stations and other equipment and working conditions. It depends on whether the monitoring program is complete or not. The complete monitoring program mainly includes the following items: monitoring items, monitoring scope, monitoring period and monitoring points.

Soil environmental monitoring usually analyzes heavy metals, trace elements, pesticides, and other pollutants in the soil. Because the soil properties are not uniform in the spatial distribution, each sampling unit is obtained by uniformly mixing several different samples. The setting of sampling points should also take care of the overall situation of the soil as much as possible and should not be too concentrated. Sampling sites usually use grid points, diagonal points, plum-shaped points, checkerboards, and serpentine points. Sampling time is determined according to the purpose of the measurement. To understand soil contaminants'R should be collected at any time to determine the soil samples, but also to understand the pollution status of the crops grown on the soil. At the same time, the soil and plant samples should be collected during the plant harvest season.
Comparison of agricultural environmental monitoring stations and biological biological monitoring found that the use of indicator plants to monitor atmospheric pollution is an effective method. The damage caused by air pollution to sensitive indicator plants is obvious. Through a large number of experiments, a list of pollution indicators for plant pollution and a color map of pollution damage were compiled. The hazards of environmental pollution can be analyzed according to the visible symptoms of biological pollution victims. Among the three methods of agricultural environmental monitoring, the sensitivity and reliability of biological monitoring Less than physical and chemical analysis methods, therefore. It can not replace the conventional method can only make a supplement.
