Development of a River Health Assessment System for the Lower Yellow River
摘要
Abstract
The lower Yellow River is highly regulated to manage problems, such as the trend towards‘less water, more sand’ .In order to improve and maintain the health of the Yellow River and support sustainable development in the river basin, the Yellow River Conservancy Commission ( YRCC) set the goal‘keep life in the Yellow River Healthy’to guide policy development and conservation planning for the Yellow River basin.Based on health assess-ments of highly regulated rivers across the country carried out in 2011-2012 by YRCC, a river health assessment system was developed for the lower Yellow River.The system includes 15 indices for assessing the ecological condi-tion and social benefits provided by the river.The river health indicator system was designed to balance ecological integrity and social services based on characteristics of the Lower Yellow River, such as hydrology and sediment transport, channel morphology, and ecology.The national indicator system for river health assessment was custom-ized for the lower Yellow River in the following ways:the flow variability index was removed from the hydrology as-sessment;flow capacity of the main channel was added to assess the physical structure of the river;The DO and bi-ochemical oxygen demand ( BOD) were integrated into the water quality assessment;the benthic integrity index was removed from the assessment of biology and habitat;the fish loss index was added to assess the status of rare, en-dangered and endemic fish and the natural wetland retention rate and habitat quality assessment were added.Drink-ing water source protection, the landscape amenities and a public satisfaction index were added to the social service function.Rather than combining the two components using a weighted average, the status of the river ecology and its social benefits were reported separately in the health assessment of the lower Yellow River.The river health as-sessment system developed in this study can be used to track the progress of management and conservation efforts on the Yellow River.It can also provide technical support for decision making related to integrated water regulation, water-sediment regulation and promoting sustainable development along the Yellow River.关键词
