Trees which shed their leave in the winter are called deciduous.
Generally speaking these are trees which grow in cold climates and do this for protection (but are not conifers, they have a different mechanism of protection).
In very cold climates the norm is high wind, rain, snow, sleet, hail and frost. Plants that are exposed to this are easily damaged by what is called frost burn (the leaves in particular); additionally the added stress of high wind, the weight of snow or ice on branches can break these limbs. So what the tree does is it sheds is leaves, this reduces the stress on the tree and prevents permanent damage to it.
The fallen leaves also have an advantage if they are not blown away, they collect around the base of the tree and act as a form of insulation which reduces root damage from frost or snow.

What gradually shuts down the leaves in plants at summers end?
The leaves gradually turn from green to oranges, reds, and yellows at the end of summer because of the chloroplasts in the leaves. Chloroplasts keep the leaves green in the summer because there is so much sunlight in the summertime, and as the sunlight gets less in the fall time, the chloroplasts get weaker and the leaves turn red, orange, and yellow.
