湛江市湖光岩风景区人工植物群落特征研究

Characteristics of Artificial Plant Community of Huguangyan Scenic Spot in Zhanjiang City

研究植物群落的基本特征对于提高群落的景观价值具有重要意义。本文根据前人的研究方法,对湛江市湖光岩风景区10个人工植物群落和5个景观节点植物种的部分数量特征进行了调查。结果表明:样地乔木和灌木排序前5位的植物重要值之和分别为38.50%和40.16%,群落内乔木和灌木应用树种搭配使用较均匀,但优势种不明显;在竹类和草本层重要值排序中,排序前2位的植物重要值差异最为明显,地毯草为主要物种,总体优势程度显著。植物物种多样性指数为乔木层>灌木层>竹类和草本层,群落中乔木层植物最为丰富。人工植物群落将湖面与环山自然植物群落有机结合在一起,给游客以美的视觉享受和心灵陶醉。建议增加乡土树种和具有地质公园特色的植物应用。

Studying the basic characteristics of plant communities is greatly significant to improve their landscape value.Based on previous research methods,this paper investigated the quantitative characteristics of 10 artificial plant communities and 5 landscape nodes plants of Huguangyan Scenic Spot in Zhanjiang City.The results showed that the sum of plant importance values of the top 5 trees and shrubs in the sample plot were 38.50%and 40.16%,respectively.The combination of tree and shrub species was more uniform,but the dominant species were not obvious.In the order of importance values of bamboo and herb layers,the difference between the top two plants was the most obvious,and Axonopus compressus was the main species with significant overall dominance.The index of plant species diversity was tree layer>shrub layer>bamboo and herb layer,and tree layer was the most abundant in the community.Artificial plant communities organically combine the lake with the natural plant communities around the mountains,giving visitors beautiful visual enjoyment and spiritual intoxication.It is suggested to increase the application of native tree species and plants with geopark characteristics.
