基于F-IBI的雅鲁藏布江中上游河流健康状况评价
River Health Assessment in the Upper and Middle Reaches of the Yarlung Zangbo River Based on the Fish Index of Biotic Integrity(F-IBI)
摘要
Abstract
Based on data collection and field monitoring,this study applies the Fish Index of Biotic Integrity(F-IBI)to systematically evaluate the river health of the upper and middle reaches of Yarlung Zangbo River mainstream and its major tributaries,and to analyze the impacts of hydropower development,overfishing and uncontrolled fish releases on aquatic ecosystems.The study area is divided into 22 river sections,and the F-IBI index is calculated using both the scoring method and the ratio method.The results show that:(a)the two calculation approaches produce different assessments of river health,in which the scoring method classifies 10 sections as healthy and 12 as fair,in contrast,the ratio method identifies only 4 sections as healthy and 18 as fair,reflecting the influence of method sensitivity on the evaluation results;and(b)overall,the upper and middle reaches of the Yarlung Zangbo River and its tributaries are in a"healthy to fair"condition,and the mainstream exhibits better health than the tributaries,and the upper-middle mainstream segments performs better than the lower segments,which is closely related to the intensity of human disturbances.The findings provide a scientific basis for fish resource conservation,habitat management,and ecological restoration in the upper and middle reaches of the Yarlung Zangbo River.关键词
