Population structure and spatial distribution pattern of Pteroceltis tatarinowii in Langyashan Mountain of Anhui Province
摘要
Abstract
Population structure and spatial distribution pattern of Pteroceltis tatarinmvii in Langyashan Mountain of Anhui Province were studied in this paper. 8 plots of 500 m2 were respectively established. Sample data obtained in contiguous grid quadrate,substituted spatial series for time series and six aggregate indexes were used in this study. The results showed:(1)Population structure of P. Tatarinmvii in 8 plots presented growing,stable or senescent type; (2)Population distributions were mostly clumped; (3) At different developmental stages,distribution pattern presented a trend from clump to random and aggregation intensity decreased somewhat; (4)Size of blocks affected the spatial distribution pattern and the pattern scales of 8 plots were about 16 m2 and 32 m2. It proved that the spatial distribution pattern of P. Tatarinmvii populations were closely related to its biological and ecological characteristics,community composition,environmental factors and human disturbance.关键词
