小区域尺度视角下的丽江市玉河健康特征研究
Study on the Health Characteristics of Yuhe River in Lijiang City from the Perspective of Small Regional Scale
摘要
Abstract
With the development of society,the process of industrialization and urbanization is accelerating,and the ecological problems of rivers and lakes are becoming increasingly prominent and showing a more complex situation.It is particularly urgent to carry out health assessment of rivers and lakes,carry out diagnosis of health problems of rivers and lakes,and put forward targeted countermeasures such as precise management,ecological restoration and protection of rivers and lakes ecosystems.The Yuhe River,a typical river in Lijiang City,is chosen as a case study.According to the four standard layers were used as important starting points,i.e.,water shoreline status,water quantity and water quality,biological status,and social service functions.A river health evaluation system with 11 index layers was constructed,and the Yuhe River was divided into three small regional scales:rural section,urban section and composite section,and a comprehensive evaluation was carried out.The results show that both the whole river and individual section of the Yuhe River are in a sub-healthy state,and the health status of the rural section,composite section and urban section of the Yuhe River is significantly different.The main problems are poor water resource endowment,small ecological flow,few benthic fauna,and poor local shoreline condition.关键词
