一、环境容量概述环境容量是表示环境自净能力的指标,是在自然状态下通过大气环流、自然界水循环、物质的氧化以及微生物的分解作用,将环境中污染物化为无害物的能力。广义而言,环境容量是指一个特定的地理空间,可以提供支持生命系统的总能力,它成为在长期稳定基础上对于该生命系统发展上线的总限制,体现了某一生态环境的最大负荷量。例如,对于人口的环境容量,就有如下定义:在不损害生物圈或不消耗资源的条件下,全球可 I. Overview of Environmental Capacity Environmental capacity is an indicator of self-purification capacity of the environment. It refers to the capacity of environmental pollutants to become harmless in the natural state through the circulation of the atmosphere, the water cycle in nature, the oxidation of substances and the decomposition of microorganisms. In broad terms, environmental capacity refers to a specific geographical space that can provide the total capacity to support a living system, which becomes the total limit on the development of the living system on a long-term and stable basis and reflects the maximum load of an ecological environment . For example, the environmental capacity of a population is defined as follows: Without compromising the biosphere or consuming resources, the global
