我区地埂坎面积约相当于耕地面积的10～20%.为了合理利用土地,增加地面被覆,保证埂坎安全,促进农业生产的发展,我们从1983年开始在三股水小流域地埂上进行造林试验,并结合定位试验,于1987年7月对该小流域内不同方位地埂类型作了初步调查.本文根据试验和调查资料,对地埂造林的立地条件,造林技术和适宜树种等问题作一初步探讨。

In order to make rational use of the land, increase the ground cover, ensure the safety of the ridge and promote the development of agricultural production, we started to work on the three basins of small watershed The afforestation experiment was carried out and the location test was carried out to make a preliminary investigation of the different types of landforms in the small watershed in July 1987. According to the experimental and investigation data, the site conditions, afforestation techniques and appropriate tree species of afforestation A preliminary discussion of the problem.
