摘要
黄荆自然保护区地处四川盆地与云贵高原的过渡地带,地带性植被为亚热带偏湿性常绿阔叶林,有种子植物165科745属1521种,其中裸子植物9科19属24种,被子植物156科726属1497种。该区特殊的自然条件和复杂的地质构造,使其成为多种植物地理成分的汇集地,并成为我国乃至全世界亚热带(同纬度)地区保存较好的常绿阔叶林植被群落,具有极高的研究价值和生态价值。根据近年来的科学考察,认为黄荆自然保护区植物区系的种类丰富、珍稀特有植物较多、起源古老、区系成分复杂,显示出多方植物交汇的特点。
Huangjin Nature Reserve was in the inter area of Sichuan Basin and Yuan-Gui Plateau, and the regional vegetation here was the subtropical evergreen broadleaf tree which was partially damp. There were seed-bearing plants of 165 families, 745 genus, and 1521 species; the gymnosperm here were of 9 families, 19 genus, and 24 species; and the angiosperm were of 156 families, 726 genus, and 1497 species. The peculiar natural conditions and complex geological constitution made it a place where many plants gathered. As an evergreen broadleaf tree vegetation colony well protected in our nation or even in the subtropical zone (the same latitude) of the whole world, it was of high research and ecological value. This paragraph was based on the scientific research and planning work of our institute on provincial nature reserve in recent years, and the focus in on the constitution and character of seed-bearing plant flora in Huangjin Nature Reserve. It was concluded that the plant flora of Huangjin Nature Reserve were rich species, many endemic and rare plants and that the origin of the flora was from far ancientry, and that the floristic elements were complex and varied.
