水平梯田

其中水平梯田、水平沟、鱼鳞坑效果好。

Among them , level terraced field , level furrow , fish-scale pits have the best effects .

土壤总孔隙度川道地为53.03%，水平梯田为50.54%，坡耕地为49.84%。

Soil porosity of the flat field is 53.03 % , the level terraced field is 50.54 % , the slope field is 49.84 % . The change of the capillary hole is not big .

当Pi30＞50mm2／min，i30＞0.28mm／min时，水平梯田的减水减沙效益随着Pi30的增大而减小。

When Pi 30 50 mm 2 / min and I 30 0.28 mm / min , the soil and water conservation benefit of level terrace is decreasing in pace with Pi 30 increasing .

以年产流降雨量和汛期雨量作为年降雨指标，经过分析发现，当年产流降雨量大于125mm和汛期雨量大于350mm时，随着雨量的增大，水平梯田的蓄水保土效益减小，呈极显著相关。

With annual rainfall output and flood season rainfall as annual rainfall index , we found the benefit would reduce with the increases of rainfall when the annual rainfall was greater than 350 mm or the flood reason rainfall was larger than 125 mm .

水土保持工程中人工修筑水平梯田的组织与方法把丘陵土地平整成为梯田，减慢水流速度，让更多的水渗到泥土里。

Leveling hilly land into terraces , which slows the rate of runoff , allows more water to soak into the soil .

水平梯田是黄土丘陵沟壑区主要的坡面治理工程，也是主要的基本农田。

Leveled terraced field is the main project of slope control and also the main capital farmland in the gullied rolling loess area .

水平梯田在具有蓄水、保土的功能的同时，也增加了土壤污染的可能性。

While level terrace had the functions of conserving soil and water storage , it increased the possibility of the soil pollution too .

以淳化试区的水平梯田为系统研究对象，休闲坡地为对照，对其剖面土壤水分变化进行动态监测。

Level terrace in Chunhua was the system studied object , fallow sloping field was the check , and their soil moisture variety was dynamic monitored .

发现由于作物对梯田土壤水分的吸收利用，以及蒸发散的原因，导致水平梯田的土壤贮水量比休闲坡地小。

This research discovered that soil pondage of level terrace were less than fallow sloping filed because of crops ' absorbing and using , and evaporation .

主要分析了水平梯田不同位置土壤水分的变化与不同年限修建水平梯田化学特性的变化。

The paper primarily analyzes the change of soil moisture in different sections of level terrace and the change of chemical properties on terrace constructed in different years .

经过30年共修水平梯田10.51万亩，占总土地面积的16.5%，占耕地面积的57.7%。

After more than 30 years ' hard work , level terraces constructed total 105,100 mu , accounting for 16.5 % total area and 57.7 % of arable lands in the county .

水平梯田措施是当地群众和广大科技工作者，在长期与水土流失作斗争的实践中，创造出防治水土流失的措施与方法之一。

Level terrace is one of the methods of preventing and cure soil erosion , which is the local masses and the masses of scientists during practice of struggling against soil erosion .
