在城市的自然 - 一种适应性的工具,可以应对未来的气候变化

未来城市博客#1在城市中的自然 - 一种适应性的工具,要应对未来的气候变化
在世界各地的城市社区中,人们被互相吸引,分享经验,交换商品和服务,以获得创新,工作或社会互动。我们的城市代表希望和机遇。

然而,许多迹象表明,我们正在朝着越来越极端的气候发展,未来包括极端热,长期干旱和恶劣天气。极端热量,除了我们的能耗增加,可能会对我们的健康产生严重影响。The consequences of climate change are set to continue to hit our cities hard and therefore an holistic approach, responding to the complexities of our cities, is required to combat these risks – what we plan for today’s cities must work tomorrow, for the cities of the future and for forthcoming generations.

我们致密的城市需要他们的性质,现在比以往任何时候都更多。今天的一大部分城市规划已经通过了解绿化与生态系统的创新,例如增加生物多样性,提高空气质量,减少二氧化碳水平,为城市人民的重要社会和娱乐价值观的创新而受到基础。虽然这些内在的内限需要进一步发展,但现在我们可以积极地和战略地利用自然来缓解预测的极端气候,并创造可持续城市。

In the cities of the future, there will be an increased need for climate regulation to balance what is known as the Urban heat island effect, which occurs when heat is stored in a city’s densified areas in hard elements such as buildings, parking areas and roads. It is apparent even today that these areas can differ by several degrees when compared to larger green areas in the city, especially at night where they cool at a slower rate.

我们的城市森林,公园,树木和植被在规范城市的温度方面发挥着关键的综合作用,因此需要通过各种重大的绿色策略进行计划,实施和保留。We need to see a re-prioritisation of the city’s surfaces, with a smaller proportion given over to hard areas that absorb heat and instead begin using a brighter and more reflective palette for building facades, roofs and ground materials in addition to an increase in permeable materials and green areas. On a smaller scale, shade needs to be provided in our cities to create environments which cater for people to pause, meet and play. The planting of new trees and creation of smaller parks can significantly improve conditions in our cities, and when partnered with a palette of robust, varied and flexible vegetation help to respond to the challenges posed towards our urban environments. Thus, the measures mentioned above provide an important base for reducing the Urban heat island effect.

在大雨的情况下,城市绿地也有助于增加吸水水平。例如,一个较大的树可以每天'喝几百百升。积极导致城市环境低洼植被区的降雨是成功模仿性质的另一种方式,因此创造了更具弹性的城市。

我们需要进一步了解并继续探索自然为我们的城市提供的有价值的机会。城市植被是处理我们在城市创造的问题和挑战的基础。我们欠了明天的城市。

与växjökommun一起一起开发了Bäckaslöv的新地区。强大的树途径,可持续的城市排水解决方案,位于较低点的休息区100年的雨处,宽阔的滨海街道部分是自然如何用于缓冲极端天气的例子。
