| 中文摘要: |
| 根据资料绘制出不同年代中国红火蚁地理分布图、分析了分布特征、并应用面积开方法尧直线距离法计
算出目前中国大陆红火蚁长距离传播速度分别为26.5尧48.1 km/年。建立了模拟入侵县级区域数量与入侵大陆时间
长度之间关系的Gauss 模型院NC=458013.8也1-0.999989EXP（-0.000001D2）页、并应用该模型预测出2023 年中国大陆被
入侵县级区域数量将达到364 个。 |
| 英文摘要: |
| Based on reported and collected data, the geographical distributtion maps of red imported fire ant,
Solenopsis invicta Buren, at different periods in China were presented, and the spatial dynamic was analyzed. Area sqrt
method and linear distance method were used to reveal the spreading speed of fire ant in mainland China as 26.5 km/a and
48.1 km/a, respectively. The model which described the relationship between invaded county number and duration after
invading the mainland China was presented as NC=458013.8也1-0.999989 EXP渊-0.000001D2冤页, and about 364 counties would be
infected in 2023. |
