沙区城市园林绿化建设初探—以酒泉市肃州区世纪大道设计为例

在对沙区城市气候特征充分了解的基本上，提出了沙区气候环境对沙区城市园林绿化的特殊要求，即降低风速、阻挡沙尘、湿润空气和调节气温。沙区城市园林绿化应遵循的主要原则是，主要街道与主害风向要有最大的夹角，林园、植物园、公园设置在上风向，主要街道上设置开放式街道公园和节水设计。其关键技术是树种的选择和结构配置。恶劣的沙区气候环境决定了沙区城市园林绿化比其他城市的园林绿化显得更为重要。第1期常兆丰沙区城市园林绿化建设初探

A Primary Study on Gardening of Cities in Sand Areas An Example of the Design of Shiji Avenue in Suzhou District of Jiuquan City

Base on climatic characteristics of cities in sand areas,special requirements of city gardening,namely reducing velocity of wind,holding up dust and sand,wetting atmosphere and adjusting air temperature,have been put forward.The main principles on city gardening of sand areas are as follows: the biggest angle between high streets and principal windy direction should be kept,gardens and park should be set up windward,open parks and facilities for water saving should be built on the main streets.The key techniques are selecting trees and arranging structure of species.The city gardening of sand areas is more important than others for the vile climate of sand areas.
