英文摘要Due to the growing concern about the agricultural phosphorus (p) losses pollution, an in-depth understanding of p in paddy soils of china would be helpful in providing a national perspective of the environmental impact of p cycling and fertility on china's farms. in this study, we evaluated the p storage and the p density of paddy soils in china, characterized the spatial variations of p among the subgroups of paddy soils and soil regions in china, and evaluated the p data using gis-based analysis, which included a newly compiled 1:1000000 digital soil map of china, and using 1490 soil profiles. the available and total p densities of paddy soils were 6.7 and 698.5 g m(-3), respectively. overall in china, the total p storage within 1 m of paddy soils was estimated to be 330.2 tg. the p density of paddy soils varied substantially with subgroups due to the different soil water regimes such as groundwater table and soil drainage. the p availability in paddy soils, especially in surface layer, was higher in high temperature and precipitation areas. further research is needed to examine more anthropogenic impact factors, such as increasing use of chemical fertilizer.
