Comparison of environmental quality assessment methods.

Evaluative dimensionName of indexExplanationAdvantageDisadvantage

Unidimensional indexThe air indicatorA unit of environmental pollutant such as sulfur dioxide, suspended matter concentration (SPM), carbon monoxide, carbon dioxide, and nitrogen oxides.Single-dimensional indicators are straightforward and easy to understand, data availability is strong, continuity is strong, it is easy to compare and study, and local environmental problems are targeted.In the process of evaluating the overall quality of the environment, there will be an overgeneralization problem.
Water environment indicatorOne kind of water pollutant is taken as the content of environmental assessment, such as industrial wastewater and chemical oxygen demand (COD).
Waste indicatorHazardous waste is taken as the index of environmental evaluation, such as solid waste and liquid waste.
Forest environmental indicatorsForest coverage rate is the main index of environmental quality evaluation.
Other indicatorsThe utilization efficiency of a certain natural resource is taken as the index of environmental comprehensive evaluation.

Multidimensional indexComprehensive indicators for the discharge of various pollutantsA variety of environmental factors are integrated into a comprehensive indicator of environmental quality, such as industrial emissions, industrial waste water emissions, and industrial solid emissions.The multidimensional environmental quality evaluation index can reflect the overall situation of environmental quality in a comprehensive way, which is conducive to an objective, fair, and reasonable comprehensive evaluation of environmental quality. It can also reflect the ability of sustainable development from the environmental dimension.Due to the lack of unified criteria for the composition of multidimensional evaluation indicators, the composition of comprehensive indicators is different, and the evaluation results are inconsistent, which is not conducive to comparison. Because the indexes are numerous, the calculation is complex, causes the result continuity to be not good, and is disadvantageous to discover the historical regularity.
Environmental sustainability indicatorsEnvironmental quality is an important part of sustainable development. The relationships between environment and society, between environment and economy, between environment and ecology, and between environment and human development are evaluated.
Environmental quality satisfaction indexTaking residents’ perceived environmental quality satisfaction as the evaluation index, the satisfaction data were obtained by means of questionnaire survey, including air quality satisfaction, water quality satisfaction, vegetation satisfaction, and acoustic environment satisfaction.
