外来植物入侵对生态旅游的影响——以云南地区的肿柄菊为例
|
摘要
外来植物入侵对于区域生态环境会产生重要影响,进而影响到区域旅游产业.该文从物种结构、生态结构、景观结构、旅游结构4个方面出发,设计了外来物种入侵对生态旅游影响的评价指标体系,并以肿柄菊(Tithonia rotundifolia)入侵对云南地区生态旅游的影响为具体案例开展了实证研究,实证结果表明:肿柄菊的入侵对于云南地区生态旅游存在有益的正向影响,尤其在对生态结构的影响方面作用明显.
The invasion of exotic plants has an important impact on the regional ecological environment, and then affects the regional tourism industry. In a study reported in this paper, starting from the four aspects of species structure, ecological structure, landscape structure and tourism structure, the authors designed an evaluation index system of the impact of exotic species invasion on ecotourism. Then an empirical case study was carried out of the invasion of Tithonia rotundifolia, an exotic plant species in Yunnan. The empirical results showed that the invasion of T. rotundifolia had a positive effect on the ecotourism in Yunnan, especially on the local ecological structure.
