流域景观的水文生态特征分析及景观生态规划方法的研究

Hydrologic-ecological characteristics of river basin landscape and ecological planning of landscape

由于城市化的快速发展,土地利用方式发生大规模改变的同时,城市河道及其沿岸景观系统在结构、形态上也发生巨大变化,导致流域水文生态系统的破坏与功能的退化,城市水涝灾害频发、水质污染严重以及景观美学质量下降等各种环境问题。以杭州市沿山河流域为例,应用景观生态学的原理,分规划的原则和方法以及河道系统的保护、修复与补偿措施,为城市的可持续发展提供科学的技术支撑。

With the fast development of urbanization and large-scale changes in land use, the river and its banks＇ landscape structure and modality suffer from great changes, which cause various environmental problems such as river hydrology breakage, ecosystem deterioration, high frequency waterlog, water pollution and landscape esthetics degradation etc. Illustrated with Yanshan River basin in Hangzhou , and based on the theory of the landscape ecology, this paper analyzes the impacts of urbanization on ecological characteristics of watershed wetland, which are hydrology balance structure and biodiversity etc. And it puts forward the principles and ways of the landscape ecological planning and approaches to protect, repair, compensate the urban river system, and to achieve its sustainable development.
