求翻译：上图中，从内向外依次是1公里以内、1~4公里、4~7公里、7~10公里、10公里以上五种出行距离对应的不同交通方式的选择。可见：在1公里以下时，同学们倾向选择步行和自行车，步行比例达到55%；1~4公里时，步行比例下降，公交以及地铁的利用都有明显提升；4~10公里时，公交车、地铁、公交换乘起到重要的作用，三者比重较为均衡占到总量的70%以上；当出行距离增至10公里以上时，公交地铁换乘也显得越来越重要，占到所有交通方式的30%，地铁位居第二，占27%，公交车占到25%。是什么意思？

The figure above, from the inside out in turn is less than 1 km, 1 to 4 km, 4 to 7 km, 10 km 10 km more than five travel distance corresponding to different modes of transportation choices. Visible: in less than one kilometer, the students tend to choose walking and cycling, walking 55%; 1 to 4 km,

In the above figure from the inside to the outside, then 1 KM, 1 to 4 KM, 4 to 7 KM, 7 to 10 KM, 10 km of distance traveled more than 5 different modes of transportation. Visible: In the 1KM, students tend to prefer walking and cycling, and walking up to 55 per cent; 1 to 4 kilometers, within walkin

In the previous illustration, from the inside out in order within 1%
