兰州住区环境要素对室外湿环境影响分析

Analysis on Outdoor Humidity Environment Influence Based on Design Factors in Lanzhou Residential Areas

兰州地处半干旱地区,湿环境是住区设计的主要因素之一。在分析住区边界条件基础上,本文提出住区湿平衡方程。通过分析住区的布局、绿化及水体等各项因素,提出各自水分影响分量公式。利用对2个住区的各项基本条件和测量气候要素,对比计算结果,对住区布局和绿化指标对住区湿环境的影响进行了分析。针对半干旱气候,提出兰州地区住区湿环境设计的基本原则。针对住区有效开口、等效高度及绿化等方面提出改善住区湿环境的设计建议。

Lanzhou is located in semi-arid area,where humid environment forms one of the main factors in residential design. Based on the analysis on the boundary condition of residential area,the paper puts forward the formula of wet balance in residential area. Through analysis the layout,greening and waters of the residential area,the paper proposes different water vapor formulas for different sources. The Influence on humidity environment of residential area by layout and green index was compared through analysis on the results based on the basic information and climatic factors by measurement. Focusing on the semiarid climate,the paper presents the general principle for humid environment design for residential area in Lanzhou. The paper finally gives proposals for design by changing the layout,equivalent height,and greening to improve humid environment in the residential area.
