P species, main as Ca-P and organic P forms, showing rego〓 pollution and karst area of lake watershed, inorganic P〓 related to Ca〓, Al〓, Fe〓 content in the overlying water, sediments is not a simple reservoir of dissolved phosphate and particle phosphate, near the interface, near 98% of total P existed as active forms, they may release to overlying water through reduction dissolution, deadsorption in the period of early diagenesis, only 2% of P as fixed forms, which mainly remained in the sediments, sediment was an important resource of nutrients of ovrelying water.

高原湖泊沉积物中的磷以有机磷和Ca-P形式存在为主，反映了高原湖泊流域污染和碳酸盐地区的整体背景，无机磷形式与水体吸附体Ca〓，Al〓和Fe〓的含量有关。底部沉积物不是溶解性磷酸盐和颗粒磷酸盐的长期储存场所，几乎有98%的磷是活性的形态存在，它们通过早期成岩作用在还原条件下还原，溶解和释放又重新回到上覆水体，只有2%的磷以固〓态的形式稳定保存于沉积物中，因此，沉积物为水体营养程度的重要来源。

The mechanisms for the differences among rice cultivars in Cd uptake and translocation There were significant differences in root oxidating abilities and soil redox potential between two typical rice cultivars, Shan you 63 and Wu yun jing 7, that are greatly different in Cd uptake from soil. The root oxidating abilities and soil Eh were accordant with Cd uptake for the cultivars. The difference between the two cultivars in Fe concentrations of root iron plaque was also significant. The cultivar with higher Fe concentrations in root iron plaque absorbed less Cd from soil.

四、水稻不同品种对镉吸收及分配存在差异的生理机理对土壤中Cd吸收能力差异很大的水稻不同品种间，根系氧化力和土壤氧化还原电位有显著差异，品种的根系氧化力和土壤氧化还原电位与该品种对Cd的吸收能力间有很好的一致性；水稻不同品种间，根表铁氧化膜的含铁量有显著差异，根表铁氧化膜含铁量高的品种，对土壤中Cd的吸收能力低；盆栽水分腾发量高及根系伤流液Cd浓度高的品种，吸收积累Cd的能力强。
