NASA新世界地图里藏的“成都秘密”

今年初，美国国家航空航天局(NASA)公布了一项最新研究报告，数据表明，世界比20年前变得更绿。在新增的绿化面积中，约四分之一来自中国，贡献比例居全球首位。在报告提供的地图中，把目光聚焦在中国西部，可以清晰看到成都龙泉山森林公园的绿色截面。

作为目前全球最大的城市森林公园，龙泉山森林公园是成都“东进”战略推进的重点区域之一。城市向东发展，翻越龙泉山，开辟“第二主战场”，成都的城市格局从“两山夹一城”变为“一山连两翼”，在突破“大城市病”瓶颈的同时，打开了面向未来的永续发展新空间。

The world is a greener place than it was twenty years ago, according to a research by NASA earlier this year. China, in particular, contributed a quarter of the world’s human-caused greening, ranking first in the world. When we look closer on the map, and focus on West China, we can see clearly the green patches that are Longquan Mountain Urban Forest Park.

As the largest city forest park in the world, Longquan Mountain Urban Forest Park is a key part of Chengdu's "Advance the East" strategy. Now under this strategy, the city opened a new space for social and economic development on the other side of the mountain. The outlook of city changed from "one city between two mountains" to "a mountain connecting two wings", breaking the bottleneck of city expansion, opening up a new space for sustainable development in the future.
