河溪利用方式对河岸带木本植物多样性的影响——以安达木河上游为例

- 摘要:
- 河溪是人类活动密集的场所，对河溪多层次多方面的利用必然会影响河岸植物的多样性。采用样带网格调查法和Shannon-weiner多样性指数分析方法，研究了安达木河上游河岸木本植物多样性对人为干扰的响应。结果表明：安达木河上游河岸乔木层植物共有19种，灌木层植物共有13种；安达木河河溪利用方式划分及其对河岸木本植物多样性的影响分别依次为：修建水库、养殖、旅游、耕种、修渠坝、村庄和自然保护区。因此，对河溪的开发利用不能只注重为当地居民带来较好经济和社会效益，还需要考虑河溪生态恢复。
- Abstract:
- Riparian plant diversity is reduced by varied stream use. By setting up sample transects and using Shannon-weiner index, this paper studied the riparian woody plant diversity and its responses to human disturbing in the upriver of Andamuhe River. The results showed that there are 19 types of trees and 13 types of shrubs. The stream use and the order of their intensities of impact on biodiversity were as follows: Reservoir > Breed aquatics > Travel sites > culture > trench and dam > rural living > nature reserve. It is recommended that economic and social benefits should be considered and stream restoration as well.
