外来入侵植物在中国的分布及入侵能力研究进展
Research progress on the distribution and invasiveness of alien invasive plants in China
摘要
Abstract
Based on the development of widely-concerned issue about exotic plant invasions in recent decades, this paper summarizes the research progress on factors determining die distribution and invasiveness of invasive plants in China, and proposes several key paints that should be emphasized in future research. It has been found that invasive plants from different geographical origins are distributed in different provinces of China. Once the geographical origins established, invasive plants are mainly distributed in provinces with fast economic development and frequent human activities at the large spatial scale, and in habitats with strong disturbance at the small spatial scale. Highly invasive perennial plants are usually clonal plants from America, which possess some typical characteristics including high photosynthetic rate and resource-use efficiency, strong allelopathic effects, and ability in adapting to heterogeneous environments. The highly invasive annuals from America typically produce large amounts of seeds, are self-compatible, and have strong allelopathic effects. The highly invasive annuals from Eurasia usually are very similar with crops in morphology, and cause severe harm to agricultural fields. Future research needs to explore how disturbances at both large and small spatial scales promote invasions, the direct and indirect effects of allelopathy in the field, the relationship between species traits and invasiveness of annuals and perennials, and the potential invasiveness of current weak invaders. These studies may not only help us to further understand the mechanisms underlying exotic plant invasions, but also provide a scientific foundation for control of current invasions and prevention of future invasions.关键词
