鱼鳞坑是水土保持坡面治理的一项工程措施,是坡地植树造林的一种整地方法。因其修筑技术简单,用工不多,拦泥蓄水和促进幼林生长作用显著,得到广泛应用。特别是当前小流域户包治理后,在土石山区成了坡面治理的主要措施。但在不少地方挖鱼鳞坑中普遍存在两个问题:一是在平面布置上稀密不均,造成一些坑控制面积过大易遭冲毁,达不到预期目的;二是坑的大小没有一定规格,有的坑小到0.3米左右,而且坑连坑,如剥皮开荒,加剧了水土流失,这都是对鱼鳞坑的概念不清造成的。为使鱼鳞坑真正起到保持水土的作用,提高经济效益,现将鱼鳞坑作一概略介绍。
The scale pit is an engineering measure for soil and water conservation slope management and is a land preparation method for afforestation on slope land. Because of its simple construction technology, small amount of labor, blocking muddy water storage and promoting the growth of young forest significantly, has been widely used. In particular, the current small watershed household management, in mountainous areas has become the main measures slope management. However, there are two problems commonly encountered in digging fish-scoops in many places: one is the unevenness of density in the layout of the layout, causing some of the pits to be oversized and easily destroyed, which can not achieve the expected purpose; the other is the size of the pits Certain specifications, some pit as small as 0.3 meters, and pit even pit, such as peeling land reclamation, exacerbated soil and water loss, which are caused by the concept of fish scale pit unclear. In order to make the fish-scale pit really play the role of maintaining the soil and water and increase economic benefits, a brief introduction of the fish-scale pit will now be made.
