极小种群野生植物坡垒的研究现状和展望
Research Status and Perspectives of Hopea hainanensis,a Wild Plant with Extremely Small Populations
摘要
Abstract
Because of the narrow distribution range,few individuals,and imperfect endangered relief technology,the wild plants with extremely small populations(WPESP)are facing the risk of extinction at any time,and need to be saved.Due to the differences in biological characteristics and endangered mechanisms of wild plants with very small populations,basic research on specific species is helpful to provide scientific basis for their conservation and population rejuvenation.Hopea hainanensis used to be the key tree species and characteristic species in the tropical rain forest of Hainan,but under the influence of human activities and regeneration difficulties,the population of H.hainanensis has decreased sharply.Although more research work has been carried out,problems such as unclear resource status,lack of mechanism research,unclear future research priorities,and failure of scientific research to effectively guide conservation practice are still prominent,and long-term,in-depth and systematic research needs to be strengthened.Based on a comprehensive search of relevant literature,the research progress of H.hainanensis was reviewed from the aspects of biological characteristics,natural distribution area,wild population size,adaptability,in situ and ex situ conservation,artificial breeding techniques and potential endangered mechanisms,and discussed the existing problems and future research priorities in the conservation of wild plants with very small populations.Based on the current research status,specific suggestions are put forward to provide reference for the protection and rescue of slope barrier.关键词
