摘要
【目的】了解红树林有害生物风险及其防控,维护红树林健康生长,发挥红树林的生态功能。【方法】2018—2019年,连续2年对广东省中山市红树林有害生物种类进行系统调查监测,并对薇甘菊和星天牛2种有害生物在中山市的分布状况、定殖和扩散的可能性、潜在危害性、受害对象的重要性、防控难度等进行分析,结合红树林的生态效益,参照国际有害生物风险性分析方法对两者在中山市红树林的危害风险性进行综合分析评估。【结果】调查发现,中山市红树林主要有害生物有23种,其中薇甘菊、星天牛最为严重,评估风险性R值分别为1.63和1.61,属中度危险的林业有害生物。【结论】薇甘菊和星天牛目前仅在中山市红树林局部地区发生危害,但具有明显扩散蔓延趋势,应该建立以应急除治、生物防治、生态修复等多种技术相结合的生态控制技术体系。
【Aim】The study examined the risk of mangrove pests and their prevention and control in order to maintain mangroves health,and their ecological function.【Method】The species of mangrove pests in Zhongshan City,Guangdong Province,were systematically investigated and monitored for two consecutive years(2018 and 2019).Combined with the ecological benefits of mangrove forests,according to the rule of pest risk analysis(PRA)of international standards for pest measurements(ISPM)and the relational model of PRA,this paper dealt with the quantitative and qualitative analysis of the risk level of Mikania micrantha and Anoplophora chinensis according to five aspects:distribution,spreading possibility,potential damaged degree,economical value of damaged host plants,and risk management difficulty.【Result】Results of the survey revealed 23 species of major pests.M.micrantha and A.chinensis were the most serious forest pests,with risk(R)values of 1.63 and 1.61,respectively.The risk analysis showed that M.micrantha and A.chinensis belonged to the middle risk level.【Conclusion】At present,M.micrantha and A.chinensis have only caused damage in the local area of mangrove in Zhongshan City,but they have an obvious tendency of spreading.It is necessary to establish an ecological control technology system that combines various technologies such as emergency elimination,biological control and ecological restoration.
