居住小区景观适应雨水自然循环的空间特征

Spatial Characters Adapted To Rainwater Natural Circulation In Residential Landscape

居住小区的绿地、广场、道路、及建筑外表不仅构成了视觉层面的小区景观,同时也是雨水的载体,关系着城市环境的生态合理性。在生态层面,小区景观没有明显的基底空间特征,而是由不占主体的软质绿地斑块、占主体的硬质建筑和广场斑块以及道路廊道构成。其中,绿地斑块的大小、走向、形状,道路廊道的曲度,对雨水自然循环有较大影响。基于景观生态学理论及杭州几个居住小区实例,本文探讨了小区景观适应雨水自然循环的空间特征,据此提出小区规划设计的五个原则,为海绵城市建设提供了低技术的途径。

In residential landscape, the visual elements of green lands, squares, roads and building facades also carry rainwater and thus imply ecological significance to urban fitness, The pattern of residential landscape is made up of minor soft patch of green land and major hard patch and corridor of buildings, squares and roads, The size, trend, and shape of soft patch, and the bend of roads are influential to rainwater natural circulation. Based upon theories of landscape ecology and examples in Hangzhou, this paper discussed spatial characters of residential landscape and outlines five planning and design principles. It provides Iow- tech approach to building sponge cities,
