how to draw the legend about color from 3d picture
Look at the color.legend function in the plotrix package to see if it does what you want. You may want to use the layout function to split the graphics device into 2 sections, one for the persp plot and the other to hold the legend. Hope this helps, -- Gregory (Greg) L.

In gnuplot, the corresponding command 'splot' will generate a picture beside to indicate the relationship between color and altitude. But in R, how to draw it? I have read the manual of legend, but they are all about how to draw a legend with colored text, not a continuous varing color with corresponding number.
