INTERSPECIFIC RELATIONSHIPS AND ENVIRONMENTAL INTERPRETATION OF THE MAIN TREE SPECIES IN THE FOREST COMMUNITIES OF ZHUWEIGOU IN LISHAN MOUNTAIN NATURE RESERVE
The interspecific relationships of the main tree species in the forest communities were studied using Fisher's exact test for a 2×2 contingency table, Pearson's correlation coefficient, Spearman's rank correlation coefficient. 1) The number of species_pairs having positive or negative correlation for Spearman's rank correlation coefficient test was higher than that of Pearson's correlation coefficient. Compared with Pearson's correlation coefficient, Spearman's rank correlation coefficient test was more sensitive. 2) Similar ecological adaptability to habitats led to positive correlation between species, and different ecological adaptability resulted in negative correlation, which was proved with environmental interpretation of interspecific relationships. 3) Based on the results, 18 tree species in the communities were divided into four ecological groups, serving as an important theory basis for studying forest structure, function, dynamics and succession.
Combining with the project background of Zhaoqing College,it summed up the campus green space planning and design principles in the western region,and systematically described its general ideas and specific plans.Through adopting innovative ideas,the learning atmosphere of the campus is caught up into the campus landscape,thus the school charm is demonstrated.
