辽宁省兴城市从1990年开始,治理荒山引进了水平槽整地形式,并且很快被山区广大干部群众所接受,使其成为荒坡治理的主要模式。以往的坡面工程形式如水平阶、水平沟、台、坑、穴等对于治理土层很薄的石质山区效果不够理想,新引进的水平槽整地措施,就是在整面荒坡上,沿等高线每隔2～3米布设一行水平槽(2.5×1.2×0.3米)以保水,槽底再挖一道换土沟(2.5×0.6×0.3米)以种树;沿每行
Since 1990, Xingcheng City, Liaoning Province, has introduced the horizontal trough land preparation form for the management of barren hills, and was quickly accepted by the vast cadres and masses in the mountainous areas, making it the main mode of harnessing the slopes. The previous slope engineering forms such as horizontal steps, horizontal ditches, stations, pits, holes and the like are not ideal for controlling the effect of the stony mountainous area where the soil layer is very thin. The newly introduced horizontal trenching site preparation measures are on the entire barren slope, A horizontal line (2.5 × 1.2 × 0.3m) shall be laid out every 2 ~ 3 meters to save water. A trench exchange (2.5 × 0.6 × 0.3m)
