海南典型有害植物的入侵扩散机理研究进展
Research progress on the mechanisms of invasion and spread of typical harmful plants in Hainan
摘要
Abstract
The population explosion of harmful plants causes significant negative impacts to agricultural and forestry ecosystems, e-conomy and the environment. This paper reviews the mechanisms of invasion and spread of the typical invasive Mikania micrantha and Eupatorium catarium and the native exploding Merremia boisiana in Hainan to provide a scientific foundation for the research and management of harmful plants in Hainan. Natural and human caused clonal stolon fragments of M. micrantha have a high regenera-tion capacity, and the regeneration capacity and subsequent growth are positively associated with the resources stored in stolon inter-nodes and leaves. E. catarium can benefit more from resource addition than native plants, indicating that disturbance and fertilization in agriculture may promote the population advantage of E. catarium relative to natives. M. boisiana has spread to natural forests in Wuzhi Mountain frequented by tourists. Surveys and transplant experiment revealed that M. boisiana may establish in disturbed forest margins and near the tourist path, and then spread to the nearby natural forests facilitated by its creeping and climbing growth forms. These results highlight the importance of disturbance, human activities, high nutrient conditions and species traits in the population explosion of harmful plants. Future studies should systematically examine the mechanisms underlying the explosion of harmful plants and their control strategies in order to reduce the harmful effects and the spreading rate and provide a safety guarantee for the devel-opment of international tourism on the island.关键词
