- Variation of Soil Nutrient and Productivity Evaluation in Nihe Watershed

- 摘要:
- 小流域土壤养分呈带状分布变化。从分水岭至塬边，土壤养分逐渐减低，沟谷从坡面到沟底滩地养分升高。不同土地利用土壤养分含量不同，呈现林草地高于园地和农地的特色。用尼尔修正生产力指数来评价土地生产力表明，林草地高于园地和农地，并与坡度呈幂函数关系。在开发黄土高原发展区域经济时，可作为参考。
- Abstract:
- Soil nutrient in small watershed demonstrates the distribution characteristics of belt pattern soil nutrient gradually reduce from rigde line to plateau border and increase from slope top to the foot of slope.Different land using causes differences in the content of soil nutrient.It is taken on a regulation that the content of soil nutrient in forest-grass land is higher than in orchard land and agriculture land.Evaluating land productivity with Neil’s modify productivity index shows:the content of soil nutrient in forest-grass land is higher than in orchard land and agriculture land and has exponential relation with slope.This result can be referred to development of economy in Loess Plateau.
