城市化进程下，植物被⽤来改善城市⽣态，美化⼈类居住环境，名曰“公园城市”计划，植物经过设计和挑选，⼀部分被栽⼊⽔泥铺装中，成为精品绿化，⼀部分则暗自生长在墙⻆墙缝，成为“杂草”。
3457900 is the total number of hectares of urban green space in China as reported by the National Bureau of Statistics for 2021.
In the process of urbanisation, plants have been
used to improve the urban environment and to
beautify the human habitat, known as the 'park
city' policy. Plants are designed and selected so
that part of them are planted in concrete pavements and become fine greenery, while part of
them grow secretly in the cracks of walls and
become "weeds".
