城市建设的不断发展促使城市人口越来越密集,这就使得人类生活环境受到各种污染的侵扰。人类的生存环境和身体健康就会受到各种威胁,从大量的科学研究可知,在城市里栽植树木、花草不仅可以对自然生态系统起到强化的作用,还可以充分利用植物将空气里面的二氧化碳等有毒气体吸走。这是因为植物通过光合作用可以释放出来氧气,使得空气里的温度和湿度得以增加,进而对小气候起到一定的调节作用,所以在城市里构建生态园林,有助于提高人类本身的生存质量,也使得人类自己可以过上幸福的生活。
The continuous development of urban construction has led to an increase in the density of urban population, which has caused the human living environment to be polluted by various kinds of pollution. Human beings’ living environment and physical health will be subject to various threats. From a large number of scientific studies, we can see that planting trees and flowers in the city can not only strengthen the natural ecosystem, but also make full use of plants’ carbon dioxide in the air. And other toxic gases suck away. This is because plants can release oxygen through photosynthesis, so that the temperature and humidity in the air can be increased, which in turn can regulate the microclimate. Therefore, building an ecological garden in the city can help improve the quality of human life. It also allows humans to live a happy life.
