摘要：

Every Walker 4-manifold M, endowed with a canonical neutral metric g, admits a specific almost complex structure called proper. In this paper, we find the conditions under which a proper almost complex structure is a harmonic section or a harmonic map from (M, g) to its hyperbolic twistor space.
