| 英文摘要 | As an important pathway for phosphorus (p) transport from soil to water body, p leaching has aroused attention. this study aimed to investigate the degree of risk and forms of p leaching from p-enriched soils. surface soils were collected from forest land (fl) and open agricultural land (oal) in typical p-enriched area of the dianchi catchment, china. based on analysis of soil p and water-soluble p using chemical methods and p-31-nmr analysis, combined with a soil column leaching experiment, p forms and risk of p leaching were identified. cacl2-extractable water-soluble organic p (cacl2-p-o), inorganic p (cacl2-p-i), and total p (cacl2-p) extracted using 0.01-m cacl2 solution were found to be useful for predicting potential organic and inorganic p leaching, given a linear, positive correlation between cacl2-p, cacl2-p-i, and cacl2-p-o in soils and accumulated amounts of corresponding p forms in soil leachates. the majority of investigated fl was at or above the change points of 46, 46, and 42 mg ap kg(-1) for cacl2-p-i, cacl2-p-o, and cacl2-p, respectively, and thus at a risk of p leaching. organic and inorganic p leaching was present in nearly all investigated oal. cacl2-p-o accounted for 66.0 % of cacl2-p in fl and 56.1 % in oal. signals of p-31-nmr spectra were mainly attributable to orthophosphate, orthophosphate monoesters, and orthophosphate diesters in fl and oal soils. it is important to consider p loss due to leaching of inorganic and organic p in p-enriched areas. |
