基于CLIMEX的柑橘冬生疫霉在我国的适生性研究

柑橘冬生疫霉( Phytophthora hibernalis Carne)是我国进境植物检疫性有害生物, 主要危害柑橘类作物, 在我国尚未有分布报道。本研究在柑橘冬生疫霉的生物学数据和中国748个站点的气象数据的基础上, 综合运用CLIMEX 2.0和ArcGIS 9.0软件对柑橘冬生疫霉在我国的适生程度和适生范围进行了预测。结果表明：柑橘冬生疫霉在我国的适生性较高, 适生范围涉及20个省、市(区), 其中, 中、高度适生区分布于浙江、福建、江西、湖南、广东、广西、四川、重庆、云南、贵州、湖北、台湾、香港。本研究明确了柑橘冬生疫霉在我国的适生性, 对科学制订针对该菌的检疫政策和措施、防范其入侵和进一步扩散具有重要意义。

The potential geographic distribution of Phytophthora hibernalis Carne based on the CLIMEX in China

Phytophthora hibernalis Carne is one of the plant quarantine pests in China, which can damage citrus crops and have not been reported in China. The potential geographic distribution of P. hibernalis was studied by using CLIMEX and ArcGIS, based on the biological data of P. hibernalis and meteorological data from 748 weather sites in China. The results showed that the suitable areas of P. hibernalis involved 20 provinces, municipalities and autonomous regions, in which Zhejiang, Fujian, Jiangxi, Hunan, Guangdong, Guangxi, Sichuan, Chongqing, Yunnan, Guizhou, Hubei, Taiwan, and Xianggang were moderately or highly suitable areas. This study defined the potential geographic distribution of P. hibernalis in China, which is important for making scientific quarantine policy and measures, and preventing invasion and further spread of P. hibernalis.
