强人类活动下流域水网演变及其供水功能影响
Evolution of watershed water networks under intense anthropogenic activities and its impact on water supply functions
摘要
Abstract
To elucidate the mechanisms through which intense anthropogenic activities reshape large-scale cross-basin water networks,this study establishes a comprehensive"morphology-structure-function"evaluation system,focusing on the receiving area of the Middle Route of the South-to-North Water Diversion(SNWD).Employing a"point(reservoir regulation)-line(river network transmission)"analytical framework,we systematically analyse the evolutionary patterns of the water network from 1960 to 2020 and quantify its water supply potential.The results reveal three distinct developmental stages:the centralized construction phase,the plateau phase,and the SNWD-dominated phase.Throughout these periods,the water network exhibited significantly enhanced morphological complexity and topological connectivity.Furthermore,the water supply function underwent a paradigm shift from"morphological expansion and local regulation"to"structural optimization and cross-basin integration".This research confirms that modern backbone water network engineering effectively overcomes morphological bottlenecks through precise structural reshaping,providing a critical theoretical basis for the optimal layout of large-scale water networks.关键词
