【摘要】 对圭峰红壤强度水土流失地实施乔、灌、草结合，针阔叶混交，ABT生根粉处理和容器苗造林等措施，进行治理试验研究，4年已初显成效，林木生长良好，地表植被增加51．6％，土壤肥力和林地小气候均有较大改善，促使了“红色沙漠”状恶劣生境向良性转化，研究表明：湿地松×胡枝子×狗牙根这种乔、灌、草复合层次结构是治理恶劣生境的优良组合模式；ABT生根粉处理及容器造林等先进造林技术是治理成功必要措施，一定资金的投入和各级部门的重视、管护则是治理成功的重要条件。更多还原

【Abstract】 The experiments of four years in controlling the serious loss of red soil and water in Guifeng has produced an initial effect. In this district such measures have been taken as planting in combination with trees, shrubs and grass, mixing coniferous leaved forest with broad leaved forest;treating with ABT rootage powder and foresting in container seedling,ect. Now the trees are growing well; The cover plants are increased by 51. 6 %; the soil fertility and microclimate in the forest have been improved; and a favorable habitat tends to be changed from the adverse habitat "the red desert". The results show that the stratified combination of Pinus elliottu ×Lespedeza bicolor × Cynodon dactylon is a good model of tackling the adverse habitat; the advanced techniques such as treatment with ABT rootage powder and forestation with containerseedling are the essential measures of the success; and the important requirements are enoughfunds,the attention and good care by the government departments at all levels as well.更多还原
