利用1979、1988、2000和2007年的土地利用遥感图像，使用autocad制图工具，依据大气污染物扩散规律，绘制出风向玫瑰图中的16个不同风向南京市江北工业区大气污染物扩散、输送对主城的影响．结果显示，随着南京主城区和江北工业区面积的不断扩大，江北工业区大气污染物对主城的影响范围在不断扩大、影响程度在不断加深；但是，江北工业区大气污染物输送和扩散不在南京主城的主导风向上侧，对主城的影响主要是在冬季，是一年中影响最大的．

According to the spread law of air pollutants, the rose diagram of wind is made, based on the land use satellite images in 1979,1988, 2000 and 2007 with the Autocad technology, indicating the way the main city of Nanjing is affected by the pollutants brought by the wind from the industrial area at the north shore of the Yangtze River in 16 different directions. The result shows that the polluted areas are getting larger and larger because of the extension of both the industrial areas and the main city. It must be npoted that the pollutant source of the northern industry, which is not on the upper side of the leading wind of the city, mainly has effects on the main city of Nan- jing in winter.
