植树真的可以逆转沙漠化吗?

沙漠的土壤其实是肥沃的,只要有一点点水,植物就可以长出来。而人工植树耗水量大,甚至吸干了沙地仅有的水。治理沙漠化的关键可能在于减少人为的干预。没有人类的影响,植物自然会长出来。但是中国人口如此多,想让人都搬出沙漠地区是不现实的。

Can planting trees really reverse desertification?

Desert soil is actually fertile, and as long as there is minimal amount of water trees will be able to grow. However, tree plantations will consume a huge quantity of water, and will suck the desert dry. The key to controlling desertification may lie in reducing human intervention. Without human interference plants will be able to grow naturally. But as China's population is so large, it is unrealistic to get people to move away from the desert.
