极端干旱对贵州省喀斯特地区植物的影响
Effects of extreme drought on plant species in Karst area of Guizhou Province, Southwest China
摘要
Abstract
Based on the investigation data of damaged vegetations in Karst areas of Guizhou Province during the extreme drought in 2010, an investigation was made on the species composition, floristic composition, life form, leaf characteristics, and environmental conditions of drought-damaged plants at six sampling plots.At these plots, there were 31 plant species drought-damaged, among which, Cunninghamia lanceolata, Celastrus orbiculatus, Rapanea neriifolia, Myrsine semiserrata,Cyclobalanopsis glauca, and Cinnamomum glanduliferum damaged most, and the tropical evergreen arbors with mesophyllous, leathery, and simple leaf suffered more seriously.The damaged plants mainly located on the middle or upper part of steep slopes, and on the thin limestone soils originated from horizontal attitude carbonate rocks.The plants in the microhabitats with soil layer <30 cm and rock-soil were damaged most, accounting for 87.4% and 40.0% of the total, respectively.It was suggested that the temperate deciduous trees with microphyll could be more planted in Karst areas,and that the microhabitat for the afforestation could be in gully and with thicker soil layer and good site condition.关键词
