竹林土壤养分变异影响因素研究进展

在竹林经营过程中，充分了解土壤养分变异的影响因素，可为维持竹林地力以及提高林分生产力提供依据。文中主要从竹林造林密度、海拔、林分模式、林分起源、经营类型、生长时期等方面阐述在不同影响因素下竹林土壤养分的变异情况，旨在让竹类经营者了解影响竹林土壤养分变异的因素，从而提高林地土壤养分利用效率，优化土壤养分变异现状，促进竹林经营的可持续发展，对提高竹林经济效益和生态效益、改善竹林立地质量具有重要的理论研究价值以及生产实践意义。

Research Progress on Influencing Factors of Soil Nutrient Variation in Bamboo Forest

In bamboo forest management, the full understanding of the influencing factors of soil nutrient variation is the foundation to maintain the soil productivity and improve the stand productivity of bamboo forests. The paper mainly expounded the variation of soil nutrient under different influencing factors in terms of plantation density, altitude, forest type, origin of forest, management type, growth period and so on, with the purpose to help bamboo managers understand the influencing factors of bamboo forest soil nutrient variation so as to increase the utilization rate of soil nutrients, optimize the soil nutrient variation and promote the sustainable bamboo forest management and development. This research would be of great theoretic research value and practical significance for improving the economic and ecological benefits of bamboo forests as well as increasing the site quality.
