福建省滨海城市雨水适应性景观应用之对策

因福建省的滨海城市大都地处沿海,所以年降水量丰富,而地带性土壤则为赤红壤的特性值得注意。随着城市化速度的加快,大量不透水铺装的使用,使得暴雨径流增大,从而引发了城市内涝、水污染以及淡水资源匮乏等问题。同时又由于地下排水基础设施即将大规模改造或者扩建,解决城市的雨水问题,便成了当务之急。在此基础上,探讨了以雨水适应性景观的方式来处理城市的雨水问题,并借鉴国外管理雨水的经验,拟建立以"线状"滞留疏导景观为骨架,结合"点状"集水景观,融合"面状"透水要素,构成初级、中级、高级三级分级削减的雨水适应性景观网络系统,从而达到了对城市雨水进行有效控制与利用的生态目标、降低基础设施投资与维护成本的经济目标以及满足城市民众游憩休闲娱乐要求的目标。

基于“海绵城市”构建的盐城市雨水适应性景观设计研究

城市水资源短缺与城市雨洪管理矛盾的加剧,推进了海绵城市建设的发展。本文着重论述海绵城市的内涵,并就城市雨水适应性景观设计原则及方法展开探讨,借鉴国外雨水管理经验,来拟建初级、中级、高级三种级别的雨水适应性景观网络体系,以促进对盐城市城市雨水的有效管理,提升盐城市城市生态环境建设水平。

浅析雨水适应性景观的应用

阐述了雨水适应性景观的概念,结合雨水的地表及屋面排放过程,介绍了雨水适应性景观的具体构成内容。

Rainwater harvesting in the challenge of droughts and climate change in semi-arid Brazil

Some successful experiences of rainwater harvesting in Brazil’s semi-arid region are shown how rural communities are living during the severe drought from 2011 to 2013 using technologies of rainwater harvesting for the household in agriculture livestock raising and the environment.Starting from the positive experiences principles of living in the challenge of droughts and climate change are elaborated and summarized into different guidelines for sustainable livelihood and production access to water and sufficient land area rainwater harvesting to provide water security to households and communities preservation recovering and management of drought-resistant vegetation emphases on raising of small and medium sized livestock and water and forage storage appropriate crop selection and sustainable extraction processing and marketing of crop products capacity building of the people. These principles contribute to preparing a national policy on living in harmony with the semi-arid climate. Rainwater harvesting is an important part of a package of measures which enables a sustainable livelihood in such a difficult environment.
