| 摘 要： | 为了研究不同规格鱼鳞坑的集水效果,确定不同立地类型条件下适宜的鱼鳞坑规格,通过鱼鳞坑集水效果指标的建立,对半干旱黄土丘陵沟壑区4种规格的鱼鳞坑集水效果的年内变化进行了对比研究。结果显示,在半阳向缓坡上,120cm×80cm×60cm或者80cm×60cm×60cm规格较适宜;半阳向陡坡和极陡坡上,80cm×60cm×6...

Catchment Effect of Fish-scale Pits with Different Specification in Semi-arid Hilly and Gully Loess Plateau |

| Abstract: | In order to study the catchment effect of fish-scale pits with different specification,and determine the suitable scale under different site types,the change of catchment effect's of 4 kind specification in a year was studied,through the establishment of catchment effect value K.The results were that 120 cm×80 cm×60 cm or 80 cm×60 cm×60 cm specifications were suitable for the gradual slopes of semi-sunny;and 80 cm×60 cm×60 cm specification was suitable for the steep and very-steep slopes of semi-sunny;however 80 cm×60 cm×60 cm or 60 cm×40 cm×60 cm specifications were suitable for the gradual slopes of shady and semi-shady.The results show that the fish-scale pits could achieve simultaneously the vegetation water used and the ecology water used.The fish-scale pits with different specifications should be established according to different site types,so with the vegetation restored,the ecological environment could also be improved effectively. |
