摘要:
采用无任何保护措施的坡耕地为对照组，系统地研究了3种典型水土保持措施：水保林、水平梯田、地埂植物带对桓仁浑江流域坡耕地总氮（Total nitrogen，TN）和总磷（total phosphorus，TP）变化的影响。2013年3—9月，共采集了336个有代表性的土壤样本进行分析研究。结果表明，采取了3种典型水土保持措施的土壤样品中的TN和TP含量均显著高于未采取任何水土保持措施坡耕地土壤中TN和TP含量。其中，水平梯田土壤中的TN和TP较对照组分别提高了24.6%和35.7%。地埂植物带土壤中的TN和TP较对照组分别提高了19.4%和37.4%。3种综合措施（水保林、水平梯田、地埂植物带）协同使用效果更为明显，可使TN和TP较对照组分别提高29.2%和30.6%。研究可为坡耕地面源污染治理提供科学依据和切实可行的方法。
Abstract:
The effect of 3 typical water and soil conservation methods (soil and water conservation forest, horizontal terrace, and terrace botanical zone) on soil total nitrogen (TN) and total phosphorus (TP) had been systematically studied in Huanren Hun River Basin, and the slope cropland was used as a control. The experiment was performed from March to September, 2013. More than 336 typical soil samples were collected and analyzed. It was found that TN and TP of soil samples collected from the area protected by the above 3 typical soil and water conservation methods were significantly higher than those collected from the slope cropland without any protection of the conventional soil and water conservation method. The TN and TP of the soil samples collected from horizontal terrace were 24.6% and 35.7% higher than those collected from the slope cropland, and the soil TN and TP from the terrace botanical zone were 19.4% and 37.4% higher, accordingly. The more dramatic effect was observed from simultaneously deploying 3 typical water and soil conservation methods together, the TN and TP of the soil samples were 29.2% and 30.6% higher, respectively, than those of the control samples. The research can provide the scientific guideline and feasible methods for the control of non-point source pollution of the sloping cropland.
