Potential Distribution Prediction of Semiothisa cinerearia in China Based on GARP Ecological Niche Model

摘要

The hazard of Semiothisa cinerearia was explosive in multiple regions of China in recent years. The potential geographic distribution of S. cinerearia in China was predicted by the GARP ecological niche model combining with terrain and climate informations. The results indicated that 8 environmental variables could improve the accuracy of prediction. The test by using 50% of all the samples showed good performance and all the known distribution points in China were all correctly predicted. The potential distribution areas of S. cinerearia included whole China except Tibet, Qinghai, Xizhang, Hainan, Taiwan and south of Guangdong and Guangxi. And the central, North, East and Northeast of China had high suitability (>90%). Measures inhibiting Sophora japonica should be taken protect early and rapidly in its suitable areas.
