摘要:

高山松(Pinus densata)群系是中国西南山区分布面积最广的松林之一, 属中国特有群系, 主要分布在四川西部、云南西北部和西藏东南部。该研究基于文献资料和野外科学考察样点, 明确了高山松林的地理分布边界, 初步摸清了高山松林的地理分布范围。利用2020-2022年调查的48个样方数据, 提出了群系分类的初步方案, 并对群落结构等特征进行了描述, 结合搜集到的2012年调查的11个样方数据, 对物种组成进行了分析。结果表明: (1)分布区跨越雅江、乡城、稻城、德钦、香格里拉、芒康、米林等33个县(市), 东起丹巴县东谷镇, 西迄桑日县增期乡, 北起壤塘县蒲西乡, 南至玉龙纳西族自治县境内的玉龙雪山, 海拔高度在(1 300) 2 500-3 800 (4 000) m之间。(2)调查到维管植物共计522种, 隶属67科222属, 其中种子植物60科209属500种, 中国特有植物42科114属233种, 区系地理成分以北温带成分占优。(3)基于群落结构和物种组成的差异, 将高山松群系进一步划分为7个群丛组、20个群丛。

Abstract:

Pinus densata Alliance is one of the most widespread pine forests in mountains of southwest China. Endemic to China, this alliance occurs in west Sichuan, northwest Yunnan, and southeast Xizang. In this study, we defined the geographic distribution boundary and priliminarily ascertained the geographic distribution area of P. densata Alliance based on previous literature and field investigation sites. Using data from 48 plots surveyed during 2020-2022, we proposed a preliminary scheme of vegetation classification and described the community structure characteristics for P. densata Alliance, and analyzed species composition characteristics combined with data from 11 plots surveyed in 2012. The results showed that (1) the distribution area of P. densata Alliance covered 33 counties and cities, including Yajiang, Xiangcheng, Daocheng, Dêqên, Xamgyi’nyilha, Markam, Mainling, and so on, at an altitude ranging from (1 300) 2 500 to 3 800 (4 000) m, and the eastern, western, northern and southern boundaries were Donggu Town in Danba County, Zengqi Township in Sangri County, Puxi Township in Zamtang County, and Yulong Snow Mountain in Yulong Naxi Autonomous County. (2) 522 vascular plant species belonging to 222 genera and 67 families were recorded, among which there were 500 seed plants belonging to 209 genera and 60 families, and 233 Chinese endemic plants belonging to 114 genera and 42 families, and the north temperate element was the dominant areal-type. (3) Based on the differences in community structure and species composition, P. densata Alliance could be classified into 7 association groups and 20 associations.
