Thinning, replanting and soil nematode diversity

With the deepening of research, more and more researchers pay attention to the impact of forest management practices on the underground part. The quality of soil and forests are also assessed by combining biotic and abiotic indicators such as soil nutrient status, soil nematode community changes. In this context, we investigated the changes in soil nematode communities, soil properties and understory plants in C. funebris plantations in the upper reaches of the Yangtze River after thinning-replanting practices. The aim of this study was to explore the effects of thinning-replanting practices on soil nematode communities and main mechanisms, providing a reference for scientific management of pure forest plantations.

随着研究的不断深入，越来越多的学者开始关注森林经营措施对地下生态系统的影响。土壤与森林的质量可通过结合生物与非生物指标进行评估，例如土壤养分状况、土壤线虫群落动态变化。在此研究背景下，本团队针对长江上游连香树（C. funebris）人工林开展调查，分析其在疏伐补植措施实施后土壤线虫群落、土壤理化性质以及林下植物的变化情况。本研究旨在探明疏伐补植措施对土壤线虫群落的影响及其核心作用机制，为纯人工林的科学经营提供参考依据。
