- Title:
- Analysis of Soil Nutrient Characteristics in Disturbed Surface and Different Slope Positions
- Keywords:
- disturbed surface; runoff plots; soil nutrient; slope position

- 摘要:
- 通过径流小区试验，研究了20 m坡长条件下人为扰动地表后不同坡位的土壤养分含量特征。研究结果表明，上坡和下坡扰动地表小区土壤养分含量均低于同一坡位自然坡面小区。其中，上坡7个养分指标含量差异均达极显著水平；下坡除土壤有机质含量差异不显著外，其他养分指标含量差异也达极显著水平。中坡，除土壤全氮、有机质及全磷含量是扰动地表小区极显著高于自然坡面小区外，其他土壤养分指标含量也是扰动地表小区极显著低于自然坡面小区。但是从整个径流小区坡面看，自然坡面小区土壤养分含量明显高于扰动地表小区。不同坡位，对于扰动地表小区，土壤氮素、钾素及有机质含量高低依次为下坡 > 中坡 > 上坡；土壤磷素含量高低依次为中坡 > 下坡 > 上坡。对于自然坡面小区，土壤氮素、钾素及有机质含量是下坡 > 上坡 > 中坡；土壤磷素含量是下坡 > 中坡 > 上坡。
- Abstract:
- Through experiments in runoff plots, this paper studied the soil nutrient characteristics in slope with 20 m long under disturbed surface and different slope positions. The results showed that the soil nutrient contents of upper and lower slope in disturbed surface plots were lower than the natural plots under the same slope position. In upper slope position, for all soil nutrients, there were very significant difference between the two kinds of plots(P < 0.01). In lower slope position, in addition to the organic matter, the other soil nutrient contents also had the very significant difference between the two kinds of plots(P < 0.01). In middle slope position, the contents of total nitrogen, organic matter and total phosphorus in disturbed surface plots were significantly higher than those in the natural plots; the contents of other soil nutrients in disturbed surface plots were also very significantly lower than those in the natural plots(P < 0.01). But judged from the all runoff plots, the contents of soil nutrients in the natural plots were significantly higher than disturbed surface plots. The nutrient contents of different slope positions, for disturbed surface plots, the contents of nitrogen, potassium and organic matter followed the sequence of lower slope > middle slope > upper slope; the content of phosphorus was in the order of middle slope > lower slope > upper slope. For the natural plots, the contents of nitrogen, potassium and organic matter followed the sequence of lower slope > upper slope > middle slope; the content of phosphorus indicated lower slope > middle slope > upper slope.
