摘　　要：以山西沁河源头将台林场为试验地点，在自然草皮和营造的人工草皮上，进行了不同植被、不同缓冲带对化肥的削弱试验。结果表明：植被带对化肥营养物质削弱作用显著；不同植被类型、不同植被宽度对不同的化肥种类消弱作用不同；在复合肥试验中，对各营养物质的消减达15％～33．3％，在硫酸钾试验中对各营养物质的消减达20％～99．3％。A runoff test with fertilizer dissolved in natural turfs and artificial turfs of different kinds of vegetation and various widths was conducted in Jiangtai forest farm at the upper Qin River in Shanxi. The results showed that the nutrients were significantly weakened by vegetation zone. Different kinds of vegetation and their widths have different weak effects on different fertilizers. During the test of compound fertilizer, nutrients elements were weakened by 15 %-33.3 %, and in the test of potassium sulfate was by 20 %-99.3 %. This test provides refer- ence for designing and implementation of buffer zone.
