- Abstract:
- The authors discuss the dynamic changing and spatial difference of cultivated land change in the Pearl River Delta according to the statistical and survey data between 1980-2004. By using regressive multianalysis equation and per demand of foodstuff, the prediction and the minimum demand for cultivated land in the Pearl River Delta are done till 2015. The results show the trends of decrease will continue and the contradiction between human and cultivated land will exacerbate. Finally, the authors put forward some advice for cultivated land protection.
