广东省西江中游地区虎舌红资源生境调查与特征分析

Investigation and Characteristic Analysis on Habitat of Ardisia mamillata Resources in the Middle Reaches of Xijiang River in Guangdong Province

摘要: 通过调查广东省西江中游3个县区鼎湖山、同乐大山、金菊顶和罗闪山4个山，每个山调查10,000 m2。这些山上都发现了虎舌红(Ardisia mamillata Hance)。按叶片表皮毛的颜色来分，有红色毛和无色毛两类虎舌红。虎舌红主要分布在海拔500 m以下较阴的滋润地。其中高要区罗闪山和郁南县金菊顶肉桂和竹林较密，虎舌红自然的生长密度和林下空地的生长密度都相当高，因此，建议这些地方应从维护生物多样性的角度，就地种植和保护虎舌红资源，同时提高林药间作的效益。

Abstract: This paper investigated the four mountains (Dinghu Mountain, Tongle Mountain, Jinju Mountain, Luoshan Mountain) in three counties in the middle reaches of the Xijiang River in Guangdong Province; area of 10,000 m2 on every mountain was surveyed. Ardisia mamillata was all found on these mountains. According to the color of the leaf epidermal hairs, the plants were divided into two categories: red hair Ardisia mamillata and colourless hair Ardisia mamillata. They distributed in the places of shade and moisture below 500 m above sea level. The cinnamon and bamboo forests are dense on the Luoshan Mountain in Gaoyao county and Jinju Mountain in Yunan county respectively; therefore the growth density of Ardisia mamillata is very high under forest space. It is suggested that based on the perspective of maintaining biodiversity in these places, Ardisia mamillata should be planted and protected, and the efficiency of intercropping forest and medicinal herbs should be improved.
