摘　　要：良好的河湖水系连通关系是河湖水系自然功能和社会功能发挥的基石,然而当前人类活动已经成为影响河湖水系连通关系的直接因素。本文在理解当前河湖水系连通战略理念的基础上,从流域宏观角度分析人类活动对河湖水系连通关系的影响,将其分为水系形态分布和水系连通状态两个影响方面。然后构建了人类活动对河湖水系连通影响量化指标体系和评估方法,通过单指标子影响系数的量化,最终得出分类层和目标层的影响量化评估等级。从人类活动影响剧烈的淮河流域实例研究结果来看,本文所构建的指标体系和量化方法是可行的。The favorable quality of River System Network Interconnected Relationship (RSNIR) is the cor-nerstone of effective natural and social functioning in Interconnected River System Network (IRSN). How-ever, human activities have become a direct factor affecting RSNIR in recent years. Taking into account na-tional strategy IRSN, this paper discusses influence of RSNIR caused by human activities from macroscopic perspective of watershed. The influence is divided into 2 types: IRSN Form Distribution Influence and Con-necting State Influence. The quantitative evaluation index system and method for human activities affecting RSNIR is established. The index system is composed of three layers, namely target layer, classification layer and index layer. By quantifying influence coefficient in each index layer according to the quantitative de-scription of single index, the influence degree in classification layer and target layer can be calculated. As a case study, the application to Huaihe River basin with intense human activity shows that the proposed system and method are feasible.
