biostudies-literatureUnknown11Shen ZTo measure intraspecific and interspecific interaction coefficients among tree species is the key to explore the underlying mechanisms for species coexistence and biodiversity maintenance in forests. Through the response surface experimental design, we established a long-term field experiment by planting 27,300 seedlings of four tree species (<i>Erythrophleum fordii</i>, <i>Pinus massoniana</i>, <i>Castanopsis fissa</i>, and <i>Castanopsis carlesii</i>) in 504 plots in different species combinations (six pairwise combinations of four species), abundance proportions (five abundance proportions of two species, i.e. A: B = 1:0, 3:1, 1:1, 1:3, 0:1), and stand densities (25, 36, 64, and 100 seedlings per plot).
