村落风水林助力山地乡村生物多样性保护——以金钱松为例

金钱松是中国最具国际影响力的古老孑遗植物之一,其面临生境破碎化、种群分散以及个体数量减少的种种威胁。幸运的是,已有研究指出村落风水林为金钱松自然种群提供了庇护,然而,村落风水林到底如何发挥保护效用,尚待深入探索。因此,该研究通过野外调查和社区访谈的方法对所有金钱松自然种群的更新现状、保护行为和干扰程度进行全面调查,并以林家塘村金钱松自然种群为例揭示金钱松村落风水林保护和管理模式。结果表明:(1)相较于其他生境类型,村落风水林生境中金钱松自然种群径级结构连续,幼苗密度较高;(2)水口林、墓地林和阳基树承载的风水与禁忌文化是村落风水林能够有效保护金钱松自然种群的内在原因;(3)新时代乡村旅游业的发展进一步促进了村民对金钱松村落风水林的保护。综上所述,在乡村振兴背景下,基于风水和禁忌文化的村落风水林保护和管理模式是金钱松自然种群保护的绝佳模式。

Village Fengshui forests contribute to the biodiversity

Pseudolarix amabilis is one of the most internationally influential ancient relict plants in China, and faces a multitude of threats, including habitat fragmentation, population isolation, and declining numbers. Fortunately, the Village Fengshui forests, sacred forests protected by Fengshui culture, has emerged as a potential refuge for the natural population of P. amabilis. Nonetheless, the underlying mechanisms by which the Village Fengshui forests safeguards the natural population of P. amabilis warrant in-depth exploration. To address this research gap, this study employed rigorous field investigations and community interviews to comprehensively assess the recruitment status, conservation behaviors, and extent of disturbances for the natural population of P. amabilis. Moreover, we selected the P. amabilis population in Linjiatang as a representative study case to elucidate the protective and management paradigm of P. amabilis Village Fengshui forests. The results were as follows:(1)The diameter at breast height(DBH)structure of P. amabilis in the Village Fengshui forests exhibited continuity, and the seedling density was higher compared to other habitat types.(2)Protecting effectiveness of Village Fengshui forests in the natural population of P. amabilis could be attributed to the Fengshui and taboo cultures associated with Shuikou forest(Village Fengshui forests near water sources), cemetery forest, and Yangji tree(heritage tree near residential houses).(3)The development of rural tourism further contributed to the preservation of P. amabilis Village Fengshui forests. In conclusion, in the context of rural revitalization, the protection and management approach based on Fengshui and taboo cultures in Village Fengshui forests presents an effective paradigm for safeguarding the natural population of P. amabilis.
