摘要
山西省水土流失面积10万平方公里,占总面积的64.1%。水土流失使土地生产力降低,水库淤积,河床抬高,水旱灾害频繁。根据当地的自然条件,建设“五层楼”的结构模式,修成水平梯田294公顷,造林906.4公顷,种草154.5公顷,取得了明显的经济效益和生态效益。开发山区的出路在于大力植树种草,发展畜牧业,加强农田基本建设,保证粮食稳产增收。治理小流域,必须建设基本农田粮食基地和多种经营商品基地,积极发展种植业。要注意解决边治理边破坏的问题。
The soil and water loss area of Shanxi Province i8 100,000 km^2, soilerosion makes land productivity lower, reservior deposited, river bedlifted, salinity, flood and drought frequent.However, significant resultsof both economy and ecology havd been obtained from the construction ofthe structure model in 'five-floor-building' and level terrace for 249 ha.forestation for 906.4 ha, planting grasses for 154.5 ha, etc. based on localnatural conditions, the way out to develop mountain areas is to harnesssmall watershed through development of animal husbandry by plantinggrasses and trees, construction of capital farml to increase yield andproduction, and growth of economic forest and so on, it is also suggestedthat the first of all is to build bases of grain and diversifiedeconomy,and to develop farming actively.Attention must be paid to the problemthat while it is harnessed it is destroyed.
