Research on Small Basin Human Settlements in Loess Plateau Base on GIS

摘要

With the wider use of digital technology in the scientific study, a research on small basin human settlements in the Loess Plateau is conducted with the overwhelming computational technologies to calculate and express. In this research, the small basins of Jiangjia River in the Loess Plateau, which is under a typical geographical circumstance, is taken as an example. In terms of the evaluation on the suitability of the natural environment of small basin human settlements in Jiangjia River by adopting the GIS functions, the detailed information on site selection, scale defining and village distribution characteristics is collected. Finally, this research is to figure out the principles which can control the future development and plan for small basin human settlements in the Loess Plateau gully region. Through the concrete research on the typical cases, it is concluded that the digital technology is supposed to be the universal means and approach to study the small basin human settlements in the Loess Plateau.
