城市绿化美化水平是衡量城市文明程度的重要指标。作为北京的中心城区，东城从古代走到现代，不知曾有过多少次变革，近些年来又经历了一场绿色革命。建国初期，东城区绿色家底并不多，1949年全区境内以公园名义开放的只有中山公园一处，还有天安门前、东长安街、正义路和景山 The level of urban afforestation and beautification is an important measure of the degree of urban civilization. As the center of Beijing, Dongcheng has gone from ancient times to modern times. I do not know how many times there have been changes and in recent years it has undergone a green revolution. In the early years of the founding of New China, there were not many green families in Dongcheng District. In 1949, there was only one Zhongshan Park opened in the name of the park in the whole district, as well as Tiananmen Square, East Chang’an Avenue, Zhengyi Road and Jingshan
