美国国家航空航天局(NASA)近日发布的研究称,与20年前相比,世界越来越绿了。
在这20年间,中国和印度始终都是全球绿化努力的领导者。
来自美国航天局地球卫星的数据显示,中国和印度的植树造林和农业等活动主导了地球变绿的过程。
该研究报告的第一作者、波士顿大学的陈驰(音)说:"这是个出人意料的发现。
因为人们普遍认为,人口密集国家的过度开发会导致土壤退化。
"而中国和印度对土地使用进行了管理,在境内大量植树并且实施农业集约化,使地球比20年前更绿了。
过去20年里地球增加的绿化面积,相当于亚马逊热带雨林的覆盖面积。
中国只占全球植被面积的6.6%,但全球植被叶面积净增长的25%都来自中国。
中国的绿化面积主要来自森林(42%)和耕地(32%),而印度的绿化面积主要来自耕地(82%),只有少部分来自森林(4.4%)。
