指出了林草植被恢复是治理石漠化的根本和有效途径,需要建立针对喀斯特石漠化区独特生态系统的研究方法。针对小区域尺度或不同流域生态系统类型,研究了其植物群落配置、生物多样性恢复与保护技术,以及需要针对不同等级石漠化造林的参考技术。在极度耐旱抗凝冻植物选育,增汇、生物能源适生植物选育与种植,以及初步恢复生态系统维护技术等方面需进一步的研究。提出了把产业链与生态链进行有机整合,建立可持续的地方生态产业,是喀斯特石漠化区植被恢复重建的一个重要发展方向。
指齣瞭林草植被恢複是治理石漠化的根本和有效途徑,需要建立針對喀斯特石漠化區獨特生態繫統的研究方法。針對小區域呎度或不同流域生態繫統類型,研究瞭其植物群落配置、生物多樣性恢複與保護技術,以及需要針對不同等級石漠化造林的參攷技術。在極度耐旱抗凝凍植物選育,增彙、生物能源適生植物選育與種植,以及初步恢複生態繫統維護技術等方麵需進一步的研究。提齣瞭把產業鏈與生態鏈進行有機整閤,建立可持續的地方生態產業,是喀斯特石漠化區植被恢複重建的一箇重要髮展方嚮。

T he restoration of vegetation is the basic and effective method for rocky desertification rehabilita-tion ,according to which ,many researchers from all works of life have done large amounts of research and a-chieved breakthrough progress in planning for types of land establishment ,analyzing the potentiality of res-toration ,the process of evolution and the modes and patterns since 90s ,20th century .But ,the objects of re-search we can find in this summary are mainly confined to single type of coenosis and vegetation located in small and partial area ,and the methods of w hich are mainly adopted that taking the place of time by space . Which has resulted in lacking of universality and authenticity ,the phenomena coming out that“planting trees but no trees ,building forests but no forests” ,“the small trees”and the singles of artificial formation of woods ,and the problems brought out that the less biological diversity and the not formation of forestry after building in several decades .The unique ecological system research methodology in karst rocky desertification area is needed .According to a small regional scale or different types of ecological systems in different levels of rocky desertification ,work on the plant configuration and the biodiversity restoration and conservation techniques .In addition ,further studies must be carried out on anti -freezing plant breeding ,breeding and cultivation of suitable bio -energy plants ,and the initial recovery and maintenance technology of eco -sys-tem .In particular ,the organic integration of the industrial and ecological chain ,and the establishment of sus-tainable local ecological industry ,will be an important direction of development of vegetation restoration in karst rocky desertification .
