A query about Beijing trees

In Beijing, I noticed quite a number of trees had their bases coloured white. Why is that so? 

A lot of the trees are Plane trees - noted for their resilience to pollution.

I think the white colour on the tree trunks is lime.  It is painted on the base of the trunk in the winter to protect the tree from the cold and excessive moisture levels as well as ward off insects.

It's as Wade, Jingyi and Christina said. Lime is used on tree trunks in my country as a kind of protection from bacteria and insects.

In Greece, people used to paint trees with lime (asbestos? Calcium?) for the bacteria. They also painted flowerpots and tall bushes.

Today, though, they just paint them with acrylics because they think it's a decorative Easter tradition.

I think it's something called lime, protecting the trees from bacteria and insects. It looks weird though.

It's not just in BJ, it's all over China. It's to protect the trees apparently. Why is it needed? I don't know, we manage fine in the UK without it.
