摘要
运用景观生态学的原理,通过对城市河道系统的景观敏感性与视觉美学敏感性的分析,指出景观系统的敏感性是指不同时间和空间尺度上系统对干扰的反应.揭示了城市化的快速发展使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,导致河流水文、生态系统的破坏与功能的退化,城市水文洪涝灾害频发、水质污染严重和美学质量下降等问题,提出用景观规划探讨城市河道系统的保护、修复与补偿系统及可持续发展途径.
Applying the principles of the landscape ecology, the paper analyzes the ecosystem sensitivity and visual esthetics sensitivity of the urban river landscape, points out that landscape sensitivity is the landscape systems＇ response to disturbance at different time and on spatial seales, and reveals that with the rapid development of urbanism and large-scale changes in land use, the river and the landscape along the river suffer from great changes in structure and form, which causes various environmental problems such as river hydrology breakage, ecosystem deterioration, high frequency waterlog, water pollution and landscape esthetics degradation, etc. Besides, it puts forward a suggestion that people should use landscape-planning methods for discussing the approach to protecting, repairing, and
