上海人多地少,人均建设用地只有47平方米。目前市区每建设一亩绿地,仅拆房动迁费就高达800多万元。面对人多地少的现实,上海的绿化建设怎样才能有新的突破呢?有关园林专家指出,上海人多地少,必须让有限的土地发挥最大的生态效益, With fewer people and more land in Shanghai, the per capita construction land is only 47 square meters. At present, every mu of green space in urban areas is built, and the relocation fee for demolition is as high as more than 8 million yuan. With regard to the fact that there are more people and less land, how can Shanghai’s green construction achieve new breakthroughs? The relevant garden experts pointed out that Shanghai has a large number of people and it is necessary to allow limited land to exert its maximum ecological benefits.
