河湖健康评价方法研究进展

随着城市化和现代化的不断发展,世界人口不断增加,污水处理能力趋于落后,大量污水未经处理排入河流和湖泊,造成严重的环境污染。梳理了国内外河湖健康评价发展历程,详细列举了预测模型法、生物完整性指数评价法和水质指数评价法的发展和应用,分析了不同评价方法和评价标准的优缺点,并对今后我国河湖健康评价工作进行了简要展望。

With the continuous development of urbanization and modernization,the population continues to increase,the sewage treatment capacity tends to lag behind,and a large amount of untreated sewage is discharged into rivers and lakes,causing serious environmental pollution.This paper reviews the development history of river and lake health assessment at home and abroad,lists the development and application of prediction model,biological integrity index and water quality index in detail,analyzes the advantages and disadvantages of different evaluation methods and evaluation criteria,and briefly prospects the future work of river health assessment in China.
