The aim of this study was to explore the response of soil solution chemistry in Dinghu Mountain broadleaf forest and coniferous forest to nitrogen deposition. Soil samples of two forest types were collected and analyzed for chemical element content. The response and adaptability of soil solution chemistry in two forest types to nitrogen deposition were studied by comparing with nitrogen deposition data. The research results can provide reference for ecological environmental protection and nitrogen deposition control in this area.Keywords: nitrogen deposition; Dinghu Mountain; broadleaf forest; coniferous forest; soil solution chemistry.引言：氮沉降已成为现代化社会环境问题之一，已被广泛关注和讨论。氮沉降对土壤、水体、生物多样性和生态系统功能等方面产生影响。鼎湖山是华南地区著名的丘陵山岭之一，该地主要森林类型为阔叶林和针叶林。近年来，鼎湖山氮沉降量增加，生态环境问题愈发严重，因此讨论其阔叶林和针叶林土壤溶液化学对氮沉降的响应，有助于解决该地区的生态环境问题。目的：本讨论旨在探讨鼎湖山阔叶林和针叶林土壤溶液化学对氮沉降的响应。通过分析两种林型土壤溶液元素含量与氮沉降数据，比较不同土壤精品文档---下载后可任意编辑溶液化学对氮沉降的响应和适应性，了解阔叶林和针叶林土壤溶液化学对氮沉降的影响，为该地区的生态环境保护和氮沉降控制提供参考。方法：1.采集样品：在鼎湖山内选择典型的阔叶林和针叶林样点，采集 0-20cm 深度的土壤，在同一时间、同一深度采集土壤溶液样品。每个样点重复...
