摘要
选取云南景洪水电站库区唯一少数民族移民搬迁村寨——江头曼咪寨为案例点,调查电站建设前后该村寨水生野菜的种类、数量及分布情况,并在此基础上归纳总结电站建设对水生野菜的影响及各影响因素之间的关联度。结果显示:电站建设对水生野菜有影响,但不同水生野菜所受的影响存在差异;电站建设对水生野菜的影响主要表现为淹没及其生境单一化所产生的直接影响,以及搬迁安置和重建所产生的间接影响;淹没前和安置中关注一些地方品种的收集和重新种植是保护生物多样性的必要手段。
The present study has been carried out to investigate the changes in quantity and distribution of aquatic and wild vegetables species before and after the dam-building in Jiangtoumanmi village, the only minority resettlement village in region of Jinghong hydropower station in Yunnan province. The data revealed that dam-building variously affected different aquatic and wild vegetables. It is necessary to collect some local species and replant them for biodiversity conservation.
