摘要/Abstract

摘要： 根据生态环境部《县域陆生高等植物多样性调查与评估技术规定》，将神农架林区划分为37个 10 km × 10 km工作网格，分析国家重点保护野生植物在林区内的空间分布格局、保护现状和潜在分布区。结果表明：(1) 神农架林区内共有国家重点保护植物84种(含变种)，其中国家一级重点保护植物7种(含变种)，国家二级重点保护植物77种(含变种)；有具体分布信息的有79种(含变种)；在科级水平上，兰科植物种类最多，在属级水平上重楼属Paris植物最多，植物生活型以草本居多。(2) 在水平分布格局中，31号网格(官门山、香溪源)内国家重点保护植物种类最多，可能与其所处大起伏中高山地带且位于大巴山脉内有关。(3) 在垂直分布格局中，中山林带(1200 m≤海拔≤2300 m)内物种丰富度最高，共有67种(含变种)国家重点保护植物，隶属于29科45属。(4) 筛选出热点区域为31号和32号网格，均在神农架国家公园内，说明热点区域基本得到完全保护，热点区域无保护空缺地，神农架国家公园内共有国家重点保护野生植物54种(含变种)，就地保护率64.29%。(5) 筛出7种典型国家重点保护野生植物，对其当前潜在分布区进行预测可知，潜在分布区主要在红坪镇、木鱼镇和大九湖等3个区域内，新华镇和阳日镇也有部分潜在分布区，而神农架林区东北部分地区基本无适生区。在7种(含变种)典型国家重点保护野生植物中，红豆杉Taxus chinensis在神农架林区内潜在分布区面积最大，占神农架林区总面积的87.02%，其中高适生区面积达1562.50 km²。

Abstract: In this study, according to the Ministry of Ecology and Environment’s Technical Regulations for Investigation and Evaluation of Terrestrial Higher Plant Diversity in County Areas, the whole Shennongjia Forest Area was divided into 37 working grids (10 km × 10 km), and the spatial distribution pattern, protection status and potential distribution area of national key protected wild plants in the forest area were analyzed. The study found that: (1) There are 84 species (including varieties) of national key protected plants in Shennongjia Forest Area, including 7 species (including varieties) of national first-level key protected plants and 77 species (including varieties) of national second-level key protected plants. There are 79 species (including varieties) which have detailed distribution information. Among them, at the family level, Orchidaceae have the most species. At the genus level, Paris has the most species, and the life form of plants is mostly herbaceous. (2) In the analysis of horizontal distribution pattern, the number of national key protected plant species in grid 31 (Guanmen Mountain, Xiangxiyuan ) is the largest, which may be related to its location in the middle and high mountain areas with large fluctuations and in the Daba Mountains. (3) In the analysis of vertical distribution pattern, Middle-altitude forest belt ( 1200 m≤alt≤2300 m ) had the highest species richness, with a total of 67 species (including varieties) of national key protected plants, belonging to 45 genera in 29 families. (4) Screening out the hot spot area for 31 and 32 grids, both in Shennongjia National Park, indicating that the hot spot area is basically fully protected, and there is no protection vacancy in the hot spot area. There are 54 species (including varieties) of national key protected wild plants in Shennongjia National Park, with an in-situ protection rate of 64.29%. (5) Seven kinds of typical national key protected wild plants were screened out, and their current potential distribution areas were predicted. The potential distribution areas were mainly in the three areas of Hongping Town, Muyu Town and Dajiuhu Lake. Xinhua Town and Yangri Town also have some potential distribution areas, while there are basically no suitable areas in the northeast part of Shennongjia Forest Area. Among the seven national key protected wild plants, Taxus chinensis has the largest potential distribution area in Shennongjia Forest Area, accounting for 87.02% of the total area of Shennongjia Forest Area, and the area of high suitable area is 1562.50 km².

Key words: Shennongjia Forest Area, national key protected wild plants, spatial distribution pattern, potential distribution area
