为了探索林木对环境的净化作用,我们于1978年同长沙市园林局协作,在长沙磷肥厂进行环境污染调查,并营造了一条防污净化试验林带。1981年8月至11月,我们对该林带及其所有树种的防污、净化效益进行了全面的测定分析,现将结果介绍于后。一、长沙磷肥厂的环境污染及防污林带概况长沙磷肥厂是一个年产钙、镁、磷肥10万吨左右的中型化肥厂,所用的磷矿石中含氟量2.93％,烟囱每小时排放废气25,200立方米,其中含氟化氢25.2—126公斤,粉尘281.2-
In order to explore the role of trees in the purification of the environment, we collaborated with the Bureau of Landscape Architecture in Changsha City in 1978 to investigate the environmental pollution in the phosphate fertilizer plant in Changsha and to create an experimental forest zone for anti-fouling purification. From August to November 1981, we conducted a comprehensive survey and analysis of the antifouling and purification benefits of the forest belt and all its species. The results are presented below. I. Overview of Environmental Pollution and Anti-fouling Forest Belt in Changsha Phosphate Fertilizer Plant Changsha Phosphate Fertilizer Plant is a medium-sized fertilizer plant with an annual output of about 100,000 tons of calcium, magnesium and phosphate fertilizers. The amount of fluorine in used phosphate rock is 2.93%, and the hourly discharge of chimneys 25,200 cubic meters of exhaust gas, including hydrogen fluoride 25.2-126 kilograms, dust 281.2-
