山西长治湿地草本植物优势种群和群落的空间格局分析
Spatial pattern analysis of herbaceous community for dominant species and communities in Changzhi wetland, Shanxi
摘要
Abstract
Spatial pattern analysis of population and community is important to reveal community structure and has become a key topic in modern plant ecology. Changzhi wetland, located in the northwest of Changzhi city,is the largest and best-preserved wetland in Shanxi province, China. Based on field investigations of herbaceous community transects, the method combines detrended correspondence analysis (DCA) ordination technique with a two-term local quadrat variance (TTLQV) method to analyse the herbaceous community pattern of dominant species and communities in Changzhi wetland. Application of the combined methods successfully revealed herbaceous community structure. The community pattern was closely correlated with that of the dominant species. The patterns of Scirpus planiculmis + Phragmites australis and Medicago minima + Paspalum paspaloides were significantly different from each other and the pattern scale gradually decreased with reduced soil moisture, and the herbaceous community patterns of dominant species and communities in Changzhi wetland were not only related to the biological characteristics of species, but were also affected by environmental factors. The small patch scale of dominant species varied from 20 to 290 cm, while the large patch scale usually varied from 900 to 1 270 cm. The results successfully showed the characteristics of species distribution and community structure of Changzhi wetland in Shanxi province.关键词
