Answer 1

为了确保脚注块位于文本块的最底部，您可以在序言中添加以下指令：

\usepackage[bottom]{footmisc}

另一个问题是文本块和页码之间的垂直空白。鉴于您正在使用该geometry包，只需提供一个较小的值（footskip当前值为30pt）即可减少空白量。

Answer 2

以下是不同垂直参数用法的（扭曲的）演示。\footskip您必须对其进行修改。请根据您的需要进行调整：

        \documentclass[a4paper, twoside, 11pt]{book}
        \usepackage[utf8]{inputenc}
        \usepackage[T1]{fontenc}
        \usepackage{kantlipsum}
        \pagestyle{plain}

        \skip\footins 2cm
        \setlength{\footnotesep}{1cm}
        \setlength{\footskip}{0pt}

        \begin{document}
        \kant{2}\footnote{This is a first footnote.}\footnote{This is a rather lengthy footnote. Just  above the page number. }
        \kant{3}
        \end{document}
