Translation of "grass-roots" into Chinese

I am here to speak to United Nations representatives on behalf of grass-roots Governments, the local governments- those that are closest to the citizens

我在这里代表基层政府,地方政府向联合国代表讲话,地方政府是最接近公民的。

Their main role lies in advocacy work and in reaching people at the grass-roots level.

它们的主要作用是开展宣传工作和联系基层群众。
