| 摘 要： | 以延安市为例,剖析了黄土高原地区在城市化建设与发展进程中造成的水土流失对城市生态环境的负面影响,指出人类城市化建设活动将加剧水土流失,并随之带来多种危害,特别是造成河流泥沙增加、河床淤积抬高,水体、土壤和空气污染,以致引发洪涝和多种地质灾害等。论文旨在引起人们的普遍重视,寻求相应的防治对策,减少城市开发建设中人为造成的水土流失,特别是在黄土高源丘陵沟壑密布、水土流失严重的地区,为建设良好的城市生态环境提供保障和服务。

| Abstract: | Seting Yanan City as an example, the soil and water loss during the urbanization in the Loess Plateau area and its negative impact on the urban eco-environment are analyzed. The human activities of urbanization will speed up the soil and water loss leading to endangerments, specially such as the increase of the silts in rives, the lift of the riverbed as sedimentary deposits, the pollution of water, soils and air, and resulted in flood and geology calamities. The aim of the article is to lead us paying more attention, to explore the protective and controlling ways and means of solving the questions, to minimize the soil and water loss due to human activities in urbanization, specially in the Loess Plateau area of dense hills and gullies resulted in serious soil and water loss, in order to provide safeguard and service to the construction of better cities'eco-environment. |
