- Abstract
Explore the distribution of soil fertility and soil nutrients is significant to the sustainable development of tropical agricultural growth. Take Bayi farm areas in Hainan province as the study area, exploring the distribution of soil fertility and nutrients in research area by applying the GIS spatial analysis tools and fuzzy mathematical theory. The results showed that the concentrations of soil organic matters, total N, available P, and available K are in moderate levels but unevenly distributed in study areas. The soil of farmland is acidic, and the value of pH is 4.8. The distribution of soil fertility is mainly determined by topography of farmland, and the higher fertility of farmland mainly distributed in areas which slope below 8°. The tools of spatial analysis can be applied in soil fertility assessment, as well as can present the spatial distribution of soil fertility. It is significant to improve the soil fertility of farmland.
