Potential Habitat Prediction of Invasive Species Flaveria Bidentis in China Based on ArcGIS and MAXENT

Abstract

The flaveria bidentis, an alien invasive plant that poses a threat to ecological stability and agricultural output, has invaded China since the early 1990s and may have the potential to spread further. An accurate assessment of its potential spread can provide a basis for early warning and prevention. The flaveria bidentis's probable habitat in China under present ecological circumstances was predicted via a maxent model that was constructed based on dispersal data and environmental factors. The result showed that the suitable habitat of the flaveria bidentis is currently widely distributed in China, making up around 3.98% of China's total land area, having a total size of about 381,795km2. The Jackknife method showed that the main factors that affected the distribution of the flaveria bidentis were the precipitation seasonality and the minimum temperature of the most frigid month. The model's AUC was 0.987, which means the precision of the forecast was quite high. The flaveria bidentis will continue to spread, therefore the pertinent departments ought to pay particular scrutiny and react promptly to set up protective measures in place.
