摘要
该文利用城市绿地有害生物风险分析体系,从病原菌传入、种群定殖、潜在的危害严重度等方面分析了栎树猝死病菌的风险性。结果表明栎树猝死病菌传入我国及其在我国定殖的风险性(R)为0.87,属于极高风险;其传入风险性(P1)、定殖风险性(P2)、潜在的危害严重度(S)值分别为0.783,0.891,0.873。
The risk of Phytophthora ramorum was analyzed with urban green space pest risk analysis system from the aspects of the introduction of the pathogen, population colonization and potential damage. The results showed the risk of the introduction and colonization of Phytophthora ramorum in China （R） was very high （0.87）. The values of risks of its introduction （ P1 ）, colonization （P2） and potential damage （S） were 0. 783,0. 891 and 0. 873 respectively.
