"Humanized River Systems“ – Influence of land use change and industry development on the morphdynamics of small rivers between uplands and lowlands: Examples from the Rur River catchment (Northrhine-Westfalia)

研究了黑龙江流域人类活动引起的土地利用变化和不同产业的发展对河漫滩形态动力学的影响。鲁尔河全长165公里，集水区面积2340平方公里，结合了现在森林覆盖的高达600米的高地和北纬200至30米之间以农业为主的低地。与中欧大多数其他河流集水区一样，人类活动导致了环境和河流形态的变化。在鲁尔河集水区，主要河流及其支流受到定居点扩大、磨坊水坝、砍伐森林、采矿活动、工业污染、水坝建设、重新造林和重新安置土地以及自然保护（如艾菲尔国家公园）的影响。本项目重点研究土地利用变化和其他人类活动在不同时期（如中世纪、现代、现在和未来）对河流系统的影响。这包括制图、取样、沉积学和地球化学分析、放射性碳和137Cs定年，以及河流和洪泛平原的数值模拟，包括水坝的影响。重点还在于不同的人类影响以及高地和低地的自然河流动态。跨学科的方法应提供汝尔河集水区的远景，以及人类从过去到现在和未来的影响。

Human induced landuse change and the development of different industries and their influence on the morphodynamic of river floodplains in the Rur River catchment are investigated. The Rur River stretches 165 km with a catchment size of 2340 km² and combines a nowadays-forested upland up to 600m with a lowland dominated by agriculture between 200 and 30 m NHN. As in most other river catchments of Central Europe, human activities caused changes in the environment and river morphology. In the Rur River catchment the main river and also its tributaries were influenced by enlargement of settlements, mill dams, deforestation, mining activities, pollutants by industries, construction of dams, re-forestation and relocation of land as well as natural conservation (e.g. National Park Eifel). This project focuses on the influence of land use change and other human activities on the fluvial systems in different times (e.g. Middle Ages, modern times, present and future) using geoscientific and engineering approaches and methods. This includes e.g. mapping, sampling, sedimentological and geochemical analysis, radiocarbon and 137Cs dating, and numeric modelling of rivers and floodplains including the influence of dams. Emphasis is also the different human impact as well as natural fluvial dynamics in the uplands and lowlands. The interdisciplinary approach shall provide a vison of the Rur River catchment and the human impact from the past to present and future.
