人类活动对河流系统的影响已经达到这样一种状态，即它们不再被认为仅受地球自然过程的控制，而且还受世界许多区域的人为力量的控制。然而，在研究人类活动与河流系统之间的反馈机制时，大多数评估方法仍然认为人类活动是外部影响，而且通常是复杂和专门的。建立了包括人工水面比(AWSR)、人工水面密度比(AWSDR)、破坏纵向连通性比(DLCR)、人工河流比(ARR)、人工截流弯度(SAC)、渠化比(CR)、人工堤防比(ALR)、沿河道路比(RARR)、人工输沙比(ASTR)和河流结构综合影响指数(IRSII)等指标体系，通过比较自然和人为作用力，定量评价人类活动对河流结构的影响。选取受人类活动剧烈影响的南流河流域对指标体系进行验证。实例分析结果表明，南流河IRSII值较高(大于0.49)，已成为一条人为河流。人工表面积和人工排沙量分别是自然过程产出量的2.96倍(AWSR=22.96)和2.51倍(ASTR=92.51)。河流被人工建筑堵塞(DLCR=68.63)，人工河道占天然河流总长度的54.23%(ARR=60.54)。在流域内，经济水平较高地区的上、下子流域受人类活动影响较大。未来南流河流域的治理应把重点放在恢复河流连通性、采砂和灌溉问题上。与以前的大多数评估方法不同，本研究开发的方法简单，公众和决策者容易理解，对长期监测具有成本效益，不受参考条件的限制。
The impact of human activities on river systems has reached a state in which they can no longer be considered to be controlled only by natural processes of the Earth but also by anthropogenic forces in many regions of world. However, most approaches for assessing the impact still consider human activities to be an external influence in the study of feedback mechanisms between human activities and river systems, and they are usually complicated and specialized. This paper aims to develop an indicator system that includes the artificial water surface ratio (AWSR), artificial water surface density ratio (AWSDR), disruption of longitudinal connectivity ratio (DLCR), artificial river ratio (ARR), sinuosity of artificial cutoff (SAC), channelization ratio (CR), artificial levee ratio (ALR), road along river ratio (RARR), artificial sediment transport ratio (ASTR) and the integrated river structure impact index (IRSII) to quantitatively assess the impact of human activities on river structure by comparing natural and anthropogenic forces in a river system. The Nanliu River basin under the dramatic impact of human activities was selected to validate the indicator system. The case results showed the Nanliu River has become an anthropogenic river according to its highIRSIIvalue (greater than 0.49). The artificial water surface area and artificial sediment discharge were 2.96 (AWSR= 2.96) and 2.51 (ASTR = 2.51) times of the outcome of natural process. The river was dramatically blocked by human-made buildings (DLCR = 68.63)and artificial channel accounts for 54.23% of total length of natural river (ARR = 0.54). Within the river basin, upper and lower sub-basins in areas with a higher economic level were more affected by human activities. Future management of the Nanliu River basin should focus on restoration of river connectivity, sand mining and irrigation issues. Unlike most previous assessment methods, the approach developed in this study is simple and readily comprehensible by the public and decision makers, cost-effective for long-term monitoring and not subject to the reference condition.
