广州市居住环境上空悬浮颗粒物分布的信息分析研究

生活环境中微尘的污染直接影响人体的健康，搞清楚悬浮颗粒在生活环境中的分布情况对环境的治理有重要意义。文中介绍了本研究组对广州市四个观察点能见情况的观察结果。对广州市四个不同功能区包括工业区、商业区、居住区和园林区的居住环境空气的浮悬颗粒物，在不同季节、不同层高进行了采样；组建了电子显微ＣＣＤ摄像系统；用所研究的纤维物剔除图像处理软件，分析了以上居住环境的浮悬颗粒物分布情况。指出广州市居住上空的浮悬颗粒物大小的分布符合指数函数分布规律，给出了ＰＭ１０以下微尘颗粒分布的分析结果及进一步应研究的内容。

Analysis for Distribution of Suspended Particle in Guangzhou Resident Environment

The dust pollution in resident environment effects human healthy. So it is important to study the distribution of suspended particle for the environment governance. This article intro-duced the results of observing visibility from four target points in Guangzhou city. The suspended particle in the atmosphere in four functional regions (industrial, commercial, resident, and gar-dens), in four seasons, and in differ floor heights is collected. An electron microscope CCD camera system is also composed and an image processing software for fiber-weeded out is developed, which were used to analyze the distribution of suspended particle. An index function could be used to describe the distribution of suspended particle in the resident environment mentioned above. At last, the result of particle below PM10 and task for further study is presented.
