园林景观中的城市热岛效应缓解措施研究 -园林专业

摘要

城市化进程的加快使得城市热岛效应日益严重，对居民生活质量和城市生态环境造成诸多负面影响。本研究旨在探讨园林景观在缓解城市热岛效应中的作用机制及有效措施。通过文献综述、实地调研与数值模拟相结合的方法，选取典型城市区域为研究对象，分析不同园林景观要素（如植被类型、水体布局、硬质铺装材料等）对地表温度和空气温度的影响。研究表明，合理配置高大乔木与低矮灌木可显著降低局部气温，增加绿地率能有效减少热辐射；引入小型水景设施有助于调节湿度并降温；采用透水性铺装材料可改善地表热交换性能。

STUDY ON MITIGATION MEASURES OF URBAN HEAT ISLAND EFFECT IN LANDSCAPE ARCHITECTURE

ABSTRACT

With the acceleration of urbanization process, the urban heat island effect becomes increasingly serious, which has many negative effects on the quality of life of residents and urban ecological environment. The purpose of this study is to explore the mechanism and effective measures of landscape architecture in alleviating urban heat island effect. By combining literature review, field investigation and numerical simulation, typical urban areas were selected as research ob jects to analyze the effects of different landscape elements (such as vegetation types, water layout, hard paving materials, etc.) on surface temperature and air temperature. The results show that reasonable allocation of tall trees and low shrubs can significantly reduce local air temperature, and increase green land rate can effectively reduce heat radiation. The introduction of small water features helps regulate humidity and cool down; The surface heat exchange performance can be improved by using permeable paving materials.
