摘要: <正>退耕还林还草工程是我国新世纪实施的六大林业生态建设工程的重要组成部分。在总结退耕还林工程区困难立地植被恢复与生态重建所取得的研究成果基础上,提出应开展耐旱树种筛选和引进树种适应性、困难立地人工造林及人工促进天然更新配套技术、提高造林成活率的新技术应用等方面的研究;探讨了植被恢复所取得的生态、经济和社会效益;阐述了在退耕还林区不同试验点开展的植被恢复和生态重建研究工作所取得的主要进展,强调了适宜树种筛选、整地方式选择、保水剂应用技术等方面的成果对困难立地植被恢复的重要作用。

Abstract: Forest rehabilitation project is an important one among six ecological construction programs of newcentury forestry development in China.Based on present research achievements on vegetation restoration and ecological reconstruction in degraded sites of forest rehabilitation areas,new research topics were suggested:selection of droughttolerant tree species and adaptation of introduced species;silvicultural technique systems and artificiallypromoted natural regeneration technology;new technique application to increase seedling survival ratio.Some potential ecological,economic and social profits from vegetation restoration have also been discussed.Finally,some research progresses have been summarized in authors’ project on forest restoration and ecological reconstruction in different experimental plots of degraded sites in China.The results could become a good reference for the practice of forest rehabilitation,including the selection of adaptive tree species and site preparation types and application of super absorbent polymers.
