广西首次发现大面积珍稀濒危植物贵州山核桃群落，生态保护成果显著
中新网南宁8月23日电 (覃永华 韦苏宁) 广西林业部门23日宣布，近日，广西林业设计院和中国科学院广西植物研究所技术团队在环江毛南族自治县开展西南岩溶国家公园创建区综合科学考察时，首次在广西发现国家二级保护野生植物贵州山核桃群落，面积超过10公顷。这一发现标志着广西生态环境保护取得了显著成果，也为岩溶石漠化区域生态治理和植被恢复提供了宝贵的经验。
据介绍，该技术团队在开展植被专项调查时，发现木论国家级自然保护区及周边分布有一个以山核桃属植物为优势种的群落。经查阅相关资料、比对标本以及植物专家鉴定，确认该物种为国家二级保护野生植物贵州山核桃。
中国科学院广西植物研究所研究员向悟生介绍，该贵州山核桃群落，大部分与青冈、化香树、南酸枣等组成石灰岩常绿落叶阔叶混交林，局部形成纯林。根据实地踏查、无人机测量以及样方调查结果，群落面积超过10公顷。山核桃树平均胸径在30厘米以上，大树胸径达70厘米以上，其分布面积大、原生性强，在国内罕见。
贵州山核桃是国家二级保护野生植物，具有重要的生态价值和科研价值。其果实营养丰富，具有药用价值，同时也是重要的生态修复树种。该群落的发现，表明西南岩溶国家公园创建区茂兰—木论片区生态环境保护良好，为岩溶石漠化区域生态治理和植被恢复提供了典型参照资料。
广西林业部门表示，将进一步加强对贵州山核桃群落的保护和研究，并积极探索其在生态修复和产业发展中的应用，为建设生态文明和美丽广西做出更大的贡献。

NANNING, Aug.23 (Xinhua) — The Guangxi Forestry Department announced on Wednesday that a large population of Guizhou hickory, a nationally protected endangered plant, has been discoveredin Guangxi for the first time. The discovery was made by a joint team from the Guangxi Forestry Design Institute and the Guangxi Institute of Botany, Chinese Academy of Sciences, during a comprehensive scientific expedition in the Southwest Karst National ParkCreation Zone in Huanjiang Maonan Autonomous County.
The team discovered the population while conducting a vegetation survey in the Mulun National Nature Reserve and its surrounding areas. After consulting relevant materials, comparing specimens, and seeking expert identification, the specieswas confirmed to be Guizhou hickory, a nationally protected wild plant.
Xiang Wusheng, a researcher at the Guangxi Institute of Botany, Chinese Academy of Sciences, explained that the Guizhou hickory population mainly coexists with species like Cyclobalanopsis glauca, Eurycorymbus cavaleriei, and Choerospondias axillaris, forming a mixed evergreen and deciduous broad-leaved forest on limestone. In some areas, it forms pure forests. Based on field surveys, drone measurements, and sample plot investigations, the population covers over 10 hectares. The average diameter at breast height of the hickorytrees exceeds 30 centimeters, with some reaching over 70 centimeters. The large distribution area and strong native character of the population are rare in China.
Guizhou hickory is a nationally protected wild plant with significant ecological and scientific value. Its fruit is rich in nutrients and has medicinal properties. It is also animportant species for ecological restoration. The discovery of this population indicates the excellent ecological environment protection in the Maolan-Mulun area of the Southwest Karst National Park Creation Zone, providing valuable reference data for ecological governance and vegetation restoration in karst rocky desertification areas.
The Guangxi Forestry Department stated that it will furtherstrengthen the protection and research of the Guizhou hickory population and actively explore its application in ecological restoration and industrial development, contributing to the construction of an ecological civilization and a beautiful Guangxi.
