In the present paper the mechanism of the appearance of zero-dimensional sinks and sources in the presence of one-dimensional basic sets of diffeomorphisms of two-dimensional surfaces, satisfying Axiom A, is studied. New examples are constructed of one-dimensional basic sets of structurally stable diffeomorphisms of the two-dimensional sphere. The existence is proved of zero-dimensional sinks and sources of diffeomorphisms of orientable surfaces of genus less than two, which are not $Y$-diffeomorphisms. An estimate is given of the number of amply situated basic sets of $A$-diffeomorphisms of orientable surfaces by means of topological invariants of the surfaces. Figures: 2. Bibliography: 17 titles.
