摘要
已有城镇格局的陕北河谷川道小城镇内涝明显,弹性应对的水适应景观能够有效改善内涝,在对城镇内涝现状及问题分析的基础上,借鉴陕北传统雨水利用经验,从宏观镇域识别和保护生态基底,中观镇区构建绿色基础设施,微观居住组团布局雨水设施三个层面提出景观设计策略,最后结合河谷川道小城镇设计案例进一步验证,以期通过对现有城镇景观格局的改造策略研究,实现不同尺度下城镇雨水层层滞蓄,提高城镇水适应能力.
Waterlogging is aggravated in small towns along river valleys in northern Shaanxi,which can be effectively improved by water adaptation landscape.Based on the analysis of the current situation and problems of towns waterlogging,the paper draws on the experience of traditional rainfall utilization in northern Shaanxi province.Landscape design strategies are put forward from three aspects,i.e.at the macro level,the recognition and protection of the ecological base of the town area.Construction of Green Infrastructure in towns at medium level.Layout of Rainwater Facilities in Residential Groups at micro level.Finally,the valley small town design case is further validated.It is hoped that through the study of the transformation strategy of the existing small town landscape pattern,the rainwater can be detained and stored in different scales,and towns water adaptability can be improved.
