AN ANALYSIS OF ADMINJISTRATIVE LEVELS OF THE FARMLAND PRODUCTIVE POTENTIALITIES IN ZHUANYAOGUO BASIN──TAKING PANICUM MILIACEUM AS AN EXAMPLK

THis paper analysed the admimstrative levels of productive potentialies and the primaryor secondary factors related to productive potentialities,established the administrative levelsof the productive potentialities,calculated the ideal productive potentialities and the practicalproductive potentialities,taking Panicum miliaceum crop in the zhuangaoguo basin in HequCounty as an example. By analysis and calculation,the paper put forward the way to improvethe production potentiality of farmland.These will provide a theoretical basis and a practicalmodel for improving the production potentiality on farmland in the basins in northwestShanxi Province.
