论地方志对王阳明文献的重构与还原

地方志在著录王阳明文献时往往对其文本进行重构,达到以光志乘的目的。或在王阳明文献的题目中添加和更换地名,以凸显文本的创作地点;或删减王阳明文献内容,以回避原有的地域特征。地方志所收文献与阳明别集所载文献的差异,可以反映阳明弟子处理阳明文献的态度与策略。阳明弟子在编排诗歌文本时,往往拼合写作时间相近、内容相似的诗歌,重新拟定总的题目;在处理序文时,有意根据文本内容选取不同稿次,甚至对文本内容进行加工和润色。在历次编刻王阳明别集的过程中,主事者偏重于篇目顺序的调整,极少考订文本的具体内容。地方志所收文献可以还原阳明文献的文本面貌,如揭示和校订别集中文献的脱讹,恢复文本的原有内容;重新议定王阳明辑供文献的著作权,探寻文本的真实作者。

为探讨西村坊村多维空心化的影响因素,通过熵权法得到各评价维度的权重。结果显示:人口空心化对整体空心化的影响最大。随后,对2010-2021年西村坊村空心化指数进行了分析,发现空心化现象逐年加剧,其中人口密度下降、土地利用不合理、经济活动转移是主要原因。通过耦合度、协调指数和耦合协调度分析了“人口—土地—经济”三元系统间的相互作用和协调关系,发现各要素之间的相互作用程度逐年增加,协调关系逐渐加强。最后,针对研究结果提出了建议:调整人口政策、优化土地利用、升级产业结构、加强政府引导与公众参与等。通过这些建议,希望能够有效解决西村坊村空心化问题,推动其经济社会的可持续发展。
