| 中文摘要: |
| 对云南乌蒙山国家级自然保护区猕猴桃属植物开展专项调查,分析其分布特点,利用MaxEnt
模型对适宜生境进行评价。结果表明,保护区内调查到猕猴桃属植物13 个种(含变种),分布点位812 个,共3 060 株,主要分布在阴坡及半阳坡山谷两边的坡面,少量零星分布在山脊,垂直分布主要集中在海拔1 200~2 100 m;适宜生境面积大于非适宜生境,约为18 237.64 hm2,占研究区面积的
68.93%,其中,低适生区、中适生区及高适生区面积分别占比47.58%、14.28%和7.07%;影响猕猴桃属植物适宜生境的主要环境因子为植被类型、距山谷距离、海拔、最湿润季度降雨量,最适生境为
海拔1 000~2 000 m范围内最湿季度降水量多的沟谷、路边林缘等地方。以期为猕猴桃种质资源的保护、管理及利用提供基础数据依据。 |
| 英文摘要: |
| The specialized investigation was conducted on plants of the Actinidia genus in the Wumengshan
National Nature Reserve of Yunnan to analyze their distribution characteristics and evaluate suitable
habitats using the MaxEnt model. The results showed that 13 species(including varieties) of Actinidia
were investigated in reserve, with 812 distribution points and a total of 3 060 individuals, mainly distributed
on shaded and semi-sunny slopes along valleys, with sporadic occurrences on ridges. The vertical distribution
was mainly concentrated at elevations between 1 200 and 2 100 m. The area of suitable habitats exceeded
that of non-suitable habitats, covering approximately 18 237.64 hm2, accounting for 68.93% of the study area, in which the low, medium, and highly suitable habitats accounted for 47.58%, 14.28%,
and 7.07% of the area, respectively. The main environmental factors influencing the suitable habitat of
Actinidia plants were vegetation type, distance from the valley, altitude and rainfall in the wettest quarter.
The most suitable habitats were found in the valley with the wettest quarter precipitation in the altitude
range of 1 000-2 000 meters, roadside forest margin and other places. This study aims to provide the
basic data basis for the protection, management and utilization of Actinidia germplasm resources. |
