Seed Rain Short-term Dynamic Characteristics and Terrain Factor Correlation Analysis in Pinus Tabulaeformis Forest in Lingkong Mountain
摘要
Abstract
In order to explore the composition of seed rain and its dynamic changes in time and space, 24 seed traps were set up in a 4hm2 Pinus tabulaeformis forest in Lingkong Mountain� Regularly collect and record the amount and type of seed rain�From September, 2014 to December, 2015 observation data shows that: we collected some seeds and fruits, belonging to 5 families, 5genus, and 6species� Pinus tabuliformis and Quercus wutaishanica, two species with the most seeds and fruits, accounted for 90% of the total� Seasonal dynamics of seed rain were analyzed� We found that: species and quantity are peak in the autumn� Analysis correlation between the seed rain density and slope direction, habitat types and slope, we found no significant correlation.关键词
