云南石漠化地区植被生态修复群落特征研究

Communities Characteristics of Vegetation Ecological Restoration in Rocky Desertification Area in Yunnan

石漠化是岩溶山区脆弱生态系统与人类不合理经济活动相互作用造成的土地退化过程。石漠化也是目前中国西南喀斯特山区生态修复与重建的重要障碍。因此,石漠化地区的景观生态修复极为迫切。以云南省红河州建水县5个石漠化地区为研究对象,通过实地调查、咨询专家和查阅相关文献资料,主要从石漠化地区植被修复场地特征、植被物种构成、植被群落特征3个方面进行研究分析,为云南省石漠化地区植被生态修复物种规划以及提升修复植被的景观性提供借鉴和参考。

Karst rocky desertifcation is a process of land degradation and dynamic evolution resulted from the fragile ecosystem in Karst mountainous regions and the improper economic activities of human beings. Rocky desertifcation is the biggest barrier for the southwest karst mountain ecosystem restoration and reconstruction. Therefore, it＇s as much urgent as important to restore the landscape ecological environment of the rocky desertifcation area. By means of feld reconnaissance, expert consulting and literature researching, the authors of this paper made a study of rocky desertifcation area in Jianshui County, Honghe Prefecture of Yunnan Province through the aspects of site characteristics of the rocky desertifcation land, plant species composition, plant community characteristics. The study provided an example and a reference to the vegetation species planning of ecological restoration of rocky desertifcation land in Yunnan.
