| Summary: | 碩士 === 逢甲大學 === 土地管理所 === 100 === The national or urban development is one of competitive approaches when the organizations are under the pressure of economic growth. The Main factor of change in ecosystem is led by human activity. The original ecosystem has been interfered by cultivation, deforestation, human development, plant introduction, and even led to the migration of native species or could not survived. The vegetation community also has the same problem.
The original vegetation communities were influenced by different form, composition or distribution. The key biological and non-biological factors which were included human factors, rainfall, soil, topography and geology. The space had cited by human activities to the development of many species in habitats besides the original and had threatened steadily native vegetation communities with unnatural distribution, growth and decline.
The research which is applying species distribution model referred the GBIF and TaiBIF data portal as data source to build the distribution. The relationship between distribution in invasive plant(Amaranthus viridis L.) and environment is discussed with maximum entropy method(Maxent), statistics methods, geographic information system(GIS), and digital elevation model. Lastly, the space database could be a reference for invasive plants in the future.
