技术领域 technical field

背景技术 Background technique
城市化进程导致一系列环境污染问题,如土壤重金属污染、雾霾、有毒气体(如二氧化硫、氮氧化物)、温室气体(如二氧化碳、甲烷)等大气污染。为解决这些环境污染问题,城市管理从源头抓起,如提升石油品质、提高机动车燃烧效率、降低私家车使用频率等,转移高能耗产业,如钢厂、石化产业等,依靠科技降低产业能耗,以最大程度的减少城市环境污染。但是,城市化进程必然产生能耗,随着工业产业的转移,城市化范围将扩大,环境污染的范围也随之扩大。因此,城市环境污染是一个系统性问题,解决城市环境污染问题,应科学运用系统运行规律。 The process of urbanization has led to a series of environmental pollution problems, such as soil heavy metal pollution, smog, toxic gases (such as sulfur dioxide, nitrogen oxides), greenhouse gases (such as carbon dioxide, methane) and other air pollution. In order to solve these environmental pollution problems, urban management starts from the source, such as improving the quality of petroleum, improving the combustion efficiency of motor vehicles, reducing the frequency of private car use, etc., transferring high-energy-consuming industries, such as steel mills and petrochemical industries, and relying on technology to reduce industrial energy consumption. consumption to minimize urban environmental pollution. However, the process of urbanization will inevitably generate energy consumption. With the transfer of industrial industries, the scope of urbanization will expand, and the scope of environmental pollution will also expand. Therefore, urban environmental pollution is a systemic problem. To solve the problem of urban environmental pollution, we should scientifically apply the laws of system operation.
虽然城市是一个人工生态系统,但与自然生态系统一样,绿色植物尤其是绿化树,是生态系统的重要生命基础。绿化树是天然的空气净化器,能够吸收二氧化碳、生产氧气、阻滞粉尘;是土壤污染防治的有效工具,能够活化土壤,促进养分循环;是城市热岛效应缓解剂,调节空气的温度和湿度,改变风向和风速,减少土壤水分蒸发,从而改善城市生态环境。不同树种对环境质量的贡献不同,因此,根据环境质量状况配置绿化树种才能够从根本上解决城市环境污染问题。 Although the city is an artificial ecosystem, like the natural ecosystem, green plants, especially green trees, are the important life basis of the ecosystem. Greening trees are natural air purifiers, which can absorb carbon dioxide, produce oxygen, and block dust; they are effective tools for soil pollution prevention and control, can activate soil, and promote nutrient cycle; they are urban heat island effect mitigants, regulating air temperature and humidity, Change the wind direction and speed to reduce the evaporation of soil moisture, thereby improving the urban ecological environment. Different tree species contribute differently to environmental quality. Therefore, the allocation of green tree species according to the environmental quality can fundamentally solve the problem of urban environmental pollution.
