摘要：

为量化云杉花墨天牛(Monochamus saltuarius)对作为松材线虫病(Bursaphelenchus xylophilus)北侵关键屏障的黑龙江省绥阳林区森林碳汇造成的损害，评估其经济影响，并提出维护区域生态安全与碳汇功能的防控策略。本研究通过标准样地调查，采用双轨碳评估法（换算因子连续函数法+蓄积量扩展法）测算生态系统碳储量，并类比松墨天牛碳损失率(34.46%)估算虫害影响，碳汇价值按150美元/t折算。结果表明云杉和冷杉贡献区域总碳储量的46.26%，其高碳密度凸显关键作用；虫害潜在发生区受害面积达18.77%，三岔河林场受害株率高达42.00%；虫害导致林分碳损失12.04万t，经济损失至少1806万美元，细鳞河与青山等资源富集林场同时为碳储核心区和虫害扩散热点。研究表明，云杉花墨天牛通过破坏高固碳树种严重威胁碳汇功能，亟需构建分区施策体系：核心区布设无人机监测网并释放天敌花绒寄甲(Dastarcus helophoroides)，过渡区采用信息素诱捕及抗性树种替代云杉纯林；同步探索“碳汇保险”对冲风险，以维护该区作为病害屏障和碳汇储备的战略功能。

Abstract:

The purpose is to quantify the damage caused by Monochamus saltuarius to the forest carbon sink of the Suiyang forest area in Heilongjiang Province, which serves as a key barrier against the northward invasion of pine wilt disease (Bursaphelenchus xylophilus), assess its economic impact, and propose prevention and control strategies to maintain regional ecological security and carbon sink function. Based on standard plot surveys, ecosystem carbon stocks were estimated using a dual-track carbon assessment approach (the conversion factor continuous function method combined with the growing stock expansion method). Pest-induced impacts were assessed by analogy with the carbon loss rate of Monochamus alternatus (34.46%), and carbon sink values were monetized at USD 150 per ton. The results indicated that spruce and fir together accounted for 46.26% of the regional total carbon stock, highlighting their critical role due to high carbon density. The potential pest-affected area reached 18.77%, with the infestation rate of damaged trees in Sanchakou Forest Farm as high as 42.00%. Pest outbreaks resulted in a forest carbon loss of 120400 t, corresponding to an economic loss of at least USD 18.06 million. Resource-rich forest farms such as Xilinhe and Qingshan were identified as both core carbon storage areas and hotspots for pest spread. The study demonstrates that Monochamus saltuarius poses a severe threat to carbon sink functions by damaging high carbon-sequestration tree species. An urgent need exists to establish a zoned management framework: deploying UAV-based monitoring networks and releasing the natural enemy Dastarcus helophoroides in core zones; applying pheromone trapping and replacing pure spruce stands with resistant tree species in transition zones. In parallel, the exploration of “carbon sink insurance” is recommended to hedge risks, thereby maintaining the strategic role of the region as both a disease barrier and a carbon sink reserve.

Key words: Monochamus saltuarius, forest carbon sinks, economic value of carbon sequestration, northward expansion of pine wilt disease, carbon sink insurance
