- 摘要:
- 以宁南山区生态建设中推广应用的典型抗旱造林整地工程为研究对象，针对工程措施的集流效果进行研究，结果表明：实施“88542”集流造林整地工程，能够有效地改善土壤的水分状况，尤其在0-60 cm土层表现较为明显；工程措施的集流效果随地形的变化有所不同：随坡位自上而下改变，“88542”集流水平沟比集流坡面水分的增加率总体上呈增大趋势；随着坡长增大，工程措施对水分增加率也呈增大趋势；随坡度的增大，水平沟相对集流面的水分增加率也随之增加；随坡向不同，工程措施的集流效果则无明显差异；相对于工程措施的集流效果，坡长和坡度之间呈正相关关系，故在工程设计中，坡度越大，相应集流坡面长度就要缩短，反之坡度越缓，集流坡面长度就要增加。
- Abstract:
- The typical site preparation engineering of drought resistance afforestation which were spread and application in ecological conservation of hilly region of southern Ningxia were made as a study object.And the rainfall-harvesting effect was learned in this paper.The results showed that: site preparation engineering of "88542" mode were effective in improving soil moisture conditions,especially on the 0-60cm soil layer.The effect of engineering measures was different with the terrain changing.With the slope of the top-down change,the increase rate of soil moisture of "88542" mode was higher than the rainfall-harvesting slope.And the increase rate of soil moisture was increasing along with slope length.The effect of rainfall-harvesting of engineering measures has no significant difference with the slope aspect.The effect of engineering measure and the slope length and gradient was positively correlated.In engineering design,the greater gradient,the corresponding rainfall-harvesting slope to shorten the length of the slope,on the contrary,the rainfall-harvesting slope to increase length of the slope.
