Abstract

Prediction of potential suitable distribution of Ambrosia artemisiifolia L. alien invasive plant in Jilin Province.

Abstract

Using combination of the MaxEnt model, ENM Tools, R language and the ArcGIS, this study predicted potential intrusion distribution regions for Ambrosia artemisiifolia in Jilin Province, determined the dominant environmental factors affecting the geographical distribution of Ambrosia artemisiifolia. The results showed that the highly and intermediate suitable regions of Ambrosia artemisiifolia were mainly distributed in most prefecture-level cities and some county-level cities in Jilin Province, among which the highly and intermediate potential suitable areas of Changchun city were the largest with 2 696.11 km2 in total, representing 13.09% of the total area of the city, followed by Siping city and Tonghua city, and the highly and intermediate potential suitable areas of Siping and Tonghua were 847.75 km2 and 555.64 km2, respectively, representing 6.06% and 3.57% of their city areas,respectively. The distribution of highly suitable regions were "tree-like" with Changchun as the center extend to the surrounding regions. The main environmental factors affecting the distribution of Ambrosia artemisiifolia were human footprint (hfp).
