林下经济模式对土壤养分循环及生物多样性的影响
摘 要
本文探讨了林下经济模式对土壤养分循环及生物多样性的影响，并分析了其实施过程中面临的挑战及优化策略。研究指出，林下经济模式通过促进土壤养分的积累与释放、改善土壤物理性质及实现养分循环利用，对土壤养分循环具有积极影响。同时，该模式还能提升物种多样性、优化生态系统结构并促进资源循环利用，对生物多样性保护具有重要意义。然而，在实施过程中，林下经济模式面临资金投入不足、经营管理水平与技术限制、林地流转困难及资源利用受限等挑战。为优化林下经济模式实施，本文建议政府加强引导与扶持，加大资金投入；加强技术培训与推广，提升经营管理水平；完善林地流转政策，保障资源有效利用。这些策略的实施将有助于推动林下经济模式的可持续发展，实现生态与经济的双赢。

IMPACT OF UNDERSTORY ECONOMIC PATTERNS ON SOIL NUTRIENT CYCLING AND BIODIVERSITY
ABSTRACT
This paper discusses the impact of undergrowth economic model on soil nutrient cycle and biodiversity, and analyzes the challenges in its implementation and optimization strategies. The study points out that the understory economic model has a positive impact on soil nutrient cycle by promoting the accumulation and release of soil nutrients, improving soil physical properties and realizing nutrient recycling. At the same time, this model can also improve the species diversity, optimize the ecosystem structure and promote the recycling of resources, which is of great significance to the biodiversity conservation. However, in the implementation process, the underforest economic model is faced with challenges such as insufficient capital investment, management level and technical restrictions, difficulties in forest land circulation and limited resource utilization. In order to optimize the implementation of underforest economic model, this paper suggests that the government should strengthen guidance and support, increase capital investment, strengthen technical training and promotion, improve the management level, and improve the policy of woodland circulation to ensure the effective utilization of resources. The implementation of these strategies will help to promote the sustainable development of the economic model and achieve win-win ecology and economy.
