Lanzhou Environmental Impact Assessment Report Write an Introduction to Common Terms (II)
(10) Water quality model. A mathematical model for describing or predicting the change law of natural water quality.
(11) Ecological impact assessment. The ecological load or environmental capacity of a region can be determined by quantitatively revealing and predicting the impact of human activities on ecology and its impact on human health and economic development.
(12) Biodiversity. The variability of various organisms within a certain space and the general name of various ecological complexes that are regularly combined. It includes gene, species and ecosystem diversity.
(13) Biological monitoring. The nature, degree and scope of environmental pollution are clarified by the reaction and impact of individual organisms, populations or communities on environmental quality and its changes, that is, the process of evaluating the nature, degree and scope of environmental quality and environmental quality from a biological perspective.
(14) Ecological monitoring. It is to observe and evaluate the natural changes of the ecosystem and the response to human changes. It is to measure the spatial and temporal pattern variables of various ecosystem structures and functions. Gansu Environmental Impact Assessment Report to write
(15) Background noise. The general name of all noises except the study object.
(16) Air pollution. The phenomenon that a substance enters the atmosphere or the secondary pollution generated from it reaches a certain concentration and duration due to human activities or natural processes, which is sufficient to have adverse effects or effects on human health, animals and plants, materials, ecology or environmental factors.
(17) Sampling of atmospheric samples. Collect samples of pollutants in the air or polluted air to obtain basic data of air pollution.
(18) Air quality assessment. According to people's specific requirements for air quality, air quality shall be qualitatively or quantitatively evaluated according to certain environmental standards, evaluation standards and certain evaluation methods.
(19) Secondary pollutants. The pollutants are divided into primary pollutants and secondary pollutants according to the generation mechanism. After the pollutants discharged directly from the pollution source are discharged into the environment, the new pollutants formed by physical factors, chemical factors or biological effects, or by reaction with other substances in the environment are secondary pollutants, also known as secondary pollutants. For example, ozone generated by photochemical reaction of nitrogen oxides and hydrocarbons under sunlight belongs to secondary pollutants.
