Suppose I have a surface parametrized by (x,y). Then I have a scalar field f(x,y), for example f(x,y) = x + y. Then I have a surface S on which a scalar field f is defined. For example defining the temperature at every point on a sphere.
 
It means there is a function defined which, to every point of the surface, assigns a scalar (number).
