【Abstract】 The distribution and pattern of man-planting vegetable in a city has strong effect on the ecological environment in the city. However, how many vegetabe we have to plant? What planting pattern is most reasonable? Where should we to plant? Authors used three dimensional vegetation quantities(VQ) to describe the amount of vegetation in a city, set up the correlative equations between the amount of VQ and the concentration of air pollutant, and developed a computer software to forecast atmosphere quantity dynamically and to support making planting decisions. The precision of the forecast can meet the permitted limits of air monitor verified by relevant precision test. The results by this research are helpful in estimation of ecologically environmental quality in a city quickly, exactly, and dynamically.更多还原
