马尾松林分结构与生态功能关系分析
摘 要
马尾松(Pinus massoniana)是我国南方重要的针叶树种,广泛分布于亚热带地区,具有显著的生态和经济价值。然而,随着人类活动和气候变化的影响,马尾松林分的结构稳定性及其生态功能面临严峻挑战。本研究旨在探讨马尾松林分结构与生态功能之间的关系,以期为森林可持续经营提供科学依据。研究选取了我国南方多个典型马尾松林分作为研究对象,通过野外调查、遥感技术和数学模型相结合的方法,系统分析了林分密度、年龄结构、物种多样性等关键指标对水源涵养、碳汇能力及土壤保持功能的影响。结果表明,合理的林分密度和年龄结构能够显著提升马尾松林的生态功能,尤其是在碳汇能力和水源涵养方面表现突出。此外,研究发现物种多样性与生态功能的正相关关系在不同地理区域表现出显著差异,这为区域性森林管理提供了新的视角。

ANALYSIS OF THE RELATIONSHIP BETWEEN THE FOREST STRUCTURE AND ECOLOGICAL FUNCTION
ABSTRACT
Masson pine (Pinus massoniana) is an important conifer species in southern China, widely distributed in subtropical areas, and has significant ecological and economic value. However, with the influence of human activities and climate change, the structural stability and its ecological function of masson pine stands face severe challenges. The purpose of this study is to investigate the relationship between forest structure and ecological function in order to provide scientific basis for sustainable forest management. Several typical masson pine stands in southern China were selected as the research ob jects, and the effects of key indicators such as forest density, age structure and species diversity on water conservation, carbon sink capacity and soil conservation function were systematically analyzed by combining field survey, remote sensing technology and mathematical model. The results show that reasonable forest density and age structure can significantly enhance the ecological function of masson pine forest, especially in carbon sink capacity and water conservation. Moreover, the positive correlation between species diversity and ecological function shows significant differences among different geographical regions, which provides a new perspective on regional forest management.
