您可以使用删除元框remove_meta_box 功能：

function wpse50430_remove_meta_boxes() {

    // make sure we\'re on an admin screen and `post` is set
    if( !is_admin() && !isset( $_GET[\'post\'] ) )
        return;

    if( $_GET[\'post\'] == 99 ): // editing page ID 99
        remove_meta_box( \'pageparentdiv\', \'page\', \'normal\' );
    endif;

}
add_action( \'admin_menu\', \'wpse50430_remove_meta_boxes\' );
