- 摘要:
- 土壤侵蚀对水体环境有着重要影响，而南方红壤丘陵区为土壤侵蚀之严重地区。丘陵沟谷是土壤与水体环境的交错地带，是侵蚀土壤进入水体的通道，通过研究该地带的养分分布特征，可以在一定程度上反映土壤侵蚀状况以及对水体质量的影响。研究结果表明，沟谷地土壤pH值变化与其位置有明显的关系，接近水体的pH值较高，在沉积点特定范围内有显著的线性关系；有机质含量在非沉积剖面中呈指数下降趋势，而在沟谷带中含量与位置密切相关，沉积点中有机质含量是呈波动性地直线下降分布；土壤全氮与有机质有很好的线性相关关系，分布模式与有机质一致；全磷含量在不同位置和深度均无显著差异，而有效磷则不同，变异较大，一般是靠近地面的含量显著高于下层。
- Abstract:
- Soil erosion has a great effect on the water environment, especially in the region with severe soil erosion potential in south China. The intervale area of upland between water and soil is the main pathway of eroded soil entering water. Experiment was conducted to investigate the distribution of soil nutrients in the intervale region. Based on the data, it could be induced to demonstrate the status of soil erosion and the effect on water quality. The results showed that the pH value was related to the position of soil in the intervale. Within the distance, pH was linear with the depth of position in the sediment. The content of organic matter decreased exponentially in the soil profile and was different among the positions in the intervale. In the sediment point, the content of organic matter decreased with depth in fluctuating. The content of nitrogen was linear with that of organic matter and its distribution was same as that of organic matter. Total phosphorus is no significance in all position, while available phosphorus is quite different from total phosphorus.
