摘要
通过试验筛选出２０余种适应干热生境和退化山地植被恢复的乔、灌、草植物，其中属澳大利亚区系类型的桉树类和相思类生长最好．在造林技术上采用内倾式水平带状整地与调控水系统建设相结合的方法，并在育苗、造林时间、造林后管理等方面进行了研究，使造林保存率提高到８０％～９０％，营建了多种不同结构和功能的植物群落，治理区森林覆盖率从原来的５％增加到现在的６５％，项目投产比达１∶２以上，初步取得了良好的社会、生态和经济效益．
More than twenty
plant species, in which some species of Eucalyptus, Acacia genus grow very well under the
dryhot environment and degraded mountainous soil, were selected from 65 local and introduced
species as silvicultural trees, shrubs and herbs by the experimental study. The level belt
terracing together with water storage system construction was thought a suitable land
preparation mode for plant growth in dry\|hot valley. Seedling growth, silvicultural reason and
management after afforestation were studied and summarized. The silvicultural survival was
enhanced to 80%90% by the methods above. Some plant communities with different structures
and functions have been set up. The forest coverage increased from 5% to 65%, and the ratio of
input and output has exceeded 12. As a result the environment is improved and social and
economic benefits are obvious.
