摘要：

黔中高原位于我国西南喀斯特山地中心区域, 该区喀斯特地貌连片发育、地质背景特殊、植被类型复杂多样, 典型植被为喀斯特常绿与落叶阔叶混交林。受人为活动影响, 该区域现存的植被主要以次生植被为主。该文利用2007-2020年生长季的植被调查数据, 对黔中高原喀斯特常绿与落叶阔叶混交林的群落学特征以及类型划分进行了较为全面系统的分析。结果表明, 该区域的典型植被主要是以青冈属(Cyclobalanopsis)、鼠刺属(Itea)、柯属(Lithocarpus)、润楠属(Machilus)、樟属(Cinnamomum)等属的常绿树种与化香树属(Platycarya)、鹅耳枥属(Carpinus)、朴属(Celtis)、栎属(Quercus)等属的落叶树种构成的常绿与落叶阔叶混交林。根据86个样方的数据统计, 共记录到维管植物585种, 隶属124科318属; 其中蕨类植物65种, 隶属11科27属; 被子植物520种, 隶属113科291属。由于生境的高度异质性, 群落物种组成复杂、类型多样。基于物种优势度原则, 将该区域的常绿与落叶阔叶混交林进一步划分为11个群系组、44个群系、83个群丛。

Abstract:

The central Guizhou Plateau is located in the center of the karst region of southwestern China. The typical vegetation type is karst mixed evergreen and deciduous broad-leaved forests on this distinct landform. Due to human disturbances, the main existing vegetation is secondary vegetation in this region. Based on the primary plot-level data obtained from fieldwork during the growing season from 2007-2020, we systematically studied the community characteristics and the classification of these karst forests. The results showed that the typical karst forests are co-dominated by evergreen trees (e.g., Cyclobalanopsis, Itea, Lithocarpus, Machilus and Cinnamomum species) and deciduous trees (e.g., Platycarya, Carpinus, Celtis and Quercus species). Moreover, 585 vascular plants belonging to 318 genera and 124 families were recorded in the 86 forest plots, among which there were 65 ferns species belonging to 27 genera and 11 families, and 520 angiosperm species belonging to 291 genera and 113 families. The karst forests show high diversities of species composition and community type. Based on the dominance principle, these karst forests were classified into 11 alliance groups, 44 alliances and 83 associations.

Key words: karst, the central Guizhou Plateau, mixed evergreen and deciduous broad-leaved forest, community structure, vegetation classification
