造林绿化,保护和培育天然植被,努力扩大绿色复盖面积,是治理水土流失的治本措施。鉴于我省水土流失严重,土壤日趋粗粒化,蓄水保水能力渐差,瘠薄干旱,甚者岩石裸露,根据省内外治理水土流失的经验,如何开发利用当地适生灌木,作为治理水土流失的先行措施,已经成为有关方面研究的主要问题。作者仅就几年来的实践,提出如下看法供商榷。 Afforestation, conservation and cultivation of natural vegetation, efforts to expand the green cover area, is the root cause of soil erosion control measures. In view of the serious soil erosion in our province, the soil is becoming increasingly coarse grained, the water storage and retention capacity is getting worse, infertile barren and even the rock is exposed, how to exploit the local adaptive shrubs and control the soil and water loss The first measures have become the major issue for the research of the parties concerned. The author puts forward the following views for discussion only on the practice of the past few years.
