摘  要：
以低山丘陵区退化生态环境为背景,对不同植被修复模式下地表径流养分特征进行研究。结果表明,地表径流不同养分间存在较大差异,养分含量大小顺序是全钾>全氮>速效氮>全磷>磷酸盐;地表径流养分在全年不同月份间和不同植被模式下均存在明显差异,多数养分的含量都以6月份为最高,每种植被模式在防止土壤特定地表径流养分损失方面各具有一定的优势,而侧柏+苜蓿模式综合效果最好;地表径流养分间的相关性分析表明,土壤全氮的径流损失同时会显著增加速效氮和磷酸盐的流失,而全磷径流损失也会明显导致速效氮养分的损失。

摘  要：
The nutrient loss by surface runoff water is the main factors of soil nutrients loss.With the degraded ecology and environment of the hilly regions as the object,the nutrients characteristics of surface runoff water under the different vegetation restoration models were studied in this article.Results showed that there is a great difference among the nutrients of surface runoff water,and the order of the nutrient content is total potassium>total nitrogen>available nitrogen>total phosphorus> phosphate.For the nutrients of surface runoff water,the great difference was found both in the different months and under the different vegetation restoration models.Most nutrients of surface runoff water have the highest content in June.Every vegetation restoration model has its advantage on controlling the particular nutrient loss of surface runoff water,and arborvitae-alfalfa model has the best comprehensive effect.The correlation analysis showed that the loss of total nitrogen would significantly increase the loss of available nitrogen and phosphate,and the loss of total phosphorus would also result in the loss of available nitrogen.
