近几年来,在水土保持治理中,存在着两个突出的问题:一是坡耕地修梯田速度慢;二是造林种草保存率低。这两个问题直接影响着治理速度、经济效益、泥沙效益和投资效益。一、修建水平梯田是治理坡耕地的根本性措施,是其它措施所不能代替的。但是,吕梁地区修筑梯田的速度却是缓慢的。根据1984年成数抽样调查,全区共有耕地1239.73万亩,其中坡耕地820.08万亩,占总耕地面积的66.1％。至1985年底已修成水平梯田143.8万亩,仅占坡耕地面积的17.5％,人均0.61亩,还有82.5％的坡耕地未治理。近
In recent years, there are two outstanding problems in soil and water conservation management: one is slow cultivation of slope in sloping fields; and the other is low preservation rate of afforestation grass. These two problems directly affect the speed of governance, economic benefits, sediment benefits and investment returns. First, the construction of horizontal terraces is a fundamental measure to control sloping farmland, which can not be replaced by other measures. However, the construction of terraced fields in Luliang is slow. According to 1984 sample survey, the total area of 1239.73 hectares of arable land, of which 820.08 mu of sloping farmland, accounting for 66.1% of the total cultivated area. By the end of 1985, it had completed 1,438,000 mu of horizontal terraces, accounting for only 17.5% of the arable land, 0.61 mu per capita, and 82.5% of the arable land remained unmanaged. near
