[交流] 求助翻译一段中文（有效期至2009年05月20日）

本文应用水蚀预报模型(WEPP)进行了以下几个方面的初步研究：首先对覆盖层边坡不同坡比、不同坡长及有无植被情况下的多年平均径流量、多年平均土壤侵蚀量等进行对比分析；然后选取某一特定坡比、特定坡长、特定年份下有无植被情况进行侵蚀控制效果分析；最后取模拟年份中的一场大暴雨进行侵蚀控制效果分析。计算结果表明：在模拟情况下，（a）覆盖层边坡越长越陡，坡地多年平均侵蚀量越大，有植被覆盖总比无植被覆盖的侵蚀量要小，且在有植被覆盖情况下，狗牙根草的侵蚀控制效果比紫穗槐灌木的要好；另外，在各种植被覆盖情况下，覆盖层顶部的土壤侵蚀量最小，底部土壤侵蚀量最大，且沿着坡面下降的方向，土壤侵蚀量呈逐渐增大趋势；（b）并不是所有的降雨都产生径流，径流量和侵蚀量与降雨量呈正相关，一般降雨量越大，径流量和侵蚀量相应也越大；在发生有效降雨时，存在裸地的侵蚀量（径流量）＞狗牙根草的侵蚀量（径流量）＞紫穗槐灌木的侵蚀量（径流量）的规律；（c）有植被覆盖较无植被覆盖能有效的减少暴雨径流量和侵蚀量，有植被覆盖的狗牙根草和紫穗槐灌木坡地沿坡向侵蚀量变化很小，而裸地沿坡向的侵蚀量变化很大，裸地最大土壤侵蚀量约为最小侵蚀量的4倍。

In this paper, Water Erosion Prediction Model (WEPP) is used in following preliminary studies: firstly, comparative analysis on the yearly average runoff and the average amount of soil erosion of coverage layer of different slope,  slope length and different vegetation, and etc; secondly,  analysis of erosion control effect under selected slope ratio, the specific slope length, year, with or without vegetation coverage; finally,  effect of erosion control of heavy rainfall in selected simulation year.

In this paper, Water Erosion Prediction Model (WEPP) to carry out the following preliminary studies: the first layer of coverage of different slope than the slope, slope length and different vegetation in case of any multi-year average runoff for many years the average amount of soil erosion, etc. Comparative analysis; and then select a particular slope ratio, the specific slope length, whether or not a given year under the situation of erosion control vegetation analysis; last year from a simulation of heavy rainfall analysis for the effect of erosion control. The results show that: in a simulated case, (a) cover the longer the steep slope, the average slope for many years the greater the erosion, and vegetation cover of the vegetation cover is better than no small amount of erosion and vegetation cover in the case , Cynodon dactylon grass effect erosion control better than the false indigo bush; In addition, vegetation cover in a variety of circumstances, cover the amount of soil erosion at the top of the smallest and the largest amount of soil erosion at the bottom, and downward along the slope direction , soil erosion was gradually increasing trend; (b) is not produced all the rainfall runoff, volume of runoff and erosion was positively correlated with rainfall, the greater the general rainfall, runoff and erosion of the greater volume of the corresponding; in effective rainfall occurs when there is erosion of bare land (runoff)> Cynodon grass erosion (runoff)> false indigo bush erosion (runoff) of the law; (c) there is less vegetation cover vegetation coverage can be effective to reduce rain runoff and erosion, and vegetation cover of bermudagrass and false indigo shrub grass slope changes in erosion along the slope is very small, and bare land erosion along the slope of a lot of changes to the biggest nude minimize soil erosion is about 4 times the amount of erosion.

The results show that: in a simulated case,
(a) the longer the steep slope of the coverage, the greater of the average erosion. amount of erosion with vegetation coverage is smaller than without it. Wire grass has better erosion control effect than river locust bush. In addition, under various circumstances, the amount of soil erosion at the top is the smallest and at the bottom is the largest, which is downward along the slope direction.
(b) Not all rainfalls produce runoff. Volumes of runoff and erosion are related to rainfall, that is the greater the rainfall, the greater volumes of runoff and erosion.When rainfall occurs, erosion of bare land > erosion of land with wire grass > erosion of land with river locust bush.

(c) Vegetation coverage can reduce runoff and erosion effectively. The erosion of land with wire grass or river locust bush reduces along with the slope direction. However, the erosion of bare land grows along with the slope direction, whose maximum is about 4 times of its minimum.
