豚草、三裂叶豚草在黑龙江省的适生区分布研究
Prediction of potential distribution areas of Ambrosia artemisiifolia and Ambrosia trifida in Heilongjiang Province
摘要
Abstract
Heilongjiang Province is the main grain-producing area in China and plays a vital role in ensuring national food security.However,the national survey of invasive organisms from 2021 to 2023,revealed that Ambrosia artemisiifolia and A.trifida are widely distributed in Heilongjiang Province,posing serious threats to local agricultural production and biodiversity.The continued spread of these species could seriously threaten China's food security.The present study investigates the suitable habitats of A.artemisiifolia and A.trifida in Heilongjiang Province using the maximum entropy model and ArcGIS software.The results show that both species exhibit high similarity in their suitable habitat ranges within Heilongjiang Province,and they extensively overlap with the primary grain-producing regions.Additionally,temperature and precipitation are identified as the principal factors influencing the distribution of A.artemisiifolia and A.trifida habitats.A.artemisiifolia demonstrates slightly stronger adaptability across multiple factors compared to A.trifida,while A.trifida prefers areas with higher levels of temperature and humidity.Therefore,the current focus should be on preventing ragweed invasion.If temperatures rise or precipitation increases,efforts to control three-lobed ragweed should be intensified.关键词
