三峡水库蓄水后长江中下游典型物理生境变化及其影响
Changes of Typical Physical Habitat and Its Impact in the Middle and Lower Reaches of Yangtze River after Impoundment of Three Gorges Reservoir
摘要
Abstract
The physical habitat of the middle and lower reaches of the Yangtze River has experienced significant changes after the impoundment of the Three Gorges Reservoir,thereby affecting river functions.Based on data anal-ysis and literature review,this paper examined the alterations in typical physical habitats such as the hydrological condition,river morphology,and vegetation after the TGR operation and their subsequent impacts on flood preven-tion,navigation,water supply,and typical aquatic organisms.Key areas for further research were identified as fol-lows:1)monitoring,including systematic and long-term monitoring programs,and the assessment of the effective-ness of river(waterway)management projects and ecological regulation measures;2)laws and mechanisms of changes in river morphology,vegetation in the main stream and shoals,and the responses and thresholds of flood levels and benthic animals to variations in the physical habitat;3)methods for predicting medium and long-term trends of hydrological conditions under the influence of multiple factors,channel regulation technologies that adapt to changes in the physical habitat and meet demands,as well as reservoir operation schemes that align with water supply objectives,benthic animal and fish breeding needs.Additionally,integrated research efforts focusing on physical habitat changes,their impacts,and improvement strategies and technologies require increased attention.关键词
