气候变化对山核桃病虫发生危害的影响初探

摘要

With many years of local data of climate change and insect pests and diseases of Chinese hickory in producing regions,the relationship between the occurrence of insect pests and diseases and climate change by mathematical method is analyzed.The results show that the occurrence of insect pests and diseases has clearly correlated with climate change.The climate warming can cause the species of insect pest and diseases increase and spread,enlarge the damaged area and cause more yield losses.%采用山核桃产区的较长年份气候资料与病虫害资料,分析了气候变化与病虫害发生的关系,运用数学方法分析了山核桃病虫害发生与气候的相关性。结果表明：气候变化与山核桃病虫危害种类有明显的相关性,气候变暖病虫危害种类增加,危害面积扩大,危害程度加重。
