The effect of Zea mays and Bromus riparius on soil and water loss were studied,the experiment was conducted to plant crop and grass in runoff-plots on the 15 degree slope naturally,the bare slop is CK,then the runoff and soil erosion amount and the biological characteristics of corn and meadow bromes termly were measured,and difference of soil and water loss prevention effect on the slop land were determined.The results showed that soil and water loss became less after both corn and meadow brome planting.And the leaf area and the coverage of meadow brome higher than corn,which was benefit for less soil and water loss at the rain season early.Meanwhile,roots of corn and meadow brome mainly distributed in 0-10 cm soil layer,and the root biomass of meadow brome was 2.88 times than that of corn.

试验在自然降雨条件下，在15°坡地设置作物与牧草径流试验小区，以裸地为对照，在每次降雨之后用全深剖面采样器取样，测量其径流量和土壤侵蚀量，定期测定玉米和草地雀麦的生物学特性，研究玉米与草地雀麦生物学特性变化及其坡地水土流失防治效果的差异，探索植物种植对坡地水土流失的主要影响因素，结果表明：种植玉米与草地雀麦，对坡地水土流失均有一定防治作用，但是，与玉米相比，草地雀麦的叶面积指数和覆盖度可在雨季前达到较高水平，有利于早期坡地水土流失防治。

We used a Mode l PS-1 PUF Sampler (Graseby GMW, Village of Cleves, OH, USA) to collect samples of total suspended particulate and n-alkanes in the gas phase. Particles were collected on quartz fiber filters. Gaseous n-alkanes were adsorbed by PUF and XAD-2 in a cartridge placed downstream of the filter holder in the sampler.

本研究使用Model PS-1 PUF采样器，以石英纤维滤纸收集总悬浮微粒，并在滤纸下游以 PUF及XAD-2吸附气相中的半挥发性有机成分。

Results showed that when the concentration of endospores in the sprayed suspension was on average 100 times greater, the numbers of droplets/particles collected in the six stages of the Andersen sampler (I.e. Would have entered the human lung) were on average 50 times greater.

结果表明，当喷洒悬浮液中芽孢浓度平均大一百倍时，六级Andersen采样器收集的雾珠/颗粒数量平均大五十倍。
