Quantitative characters of standing dead trees of the evergreen broadleaved forest in Nanling National Nature Reserve, Guangdong, China
摘要
Abstract
Using the classic survey method, quantitative characters of standing dead trees of 3 forest communities under different protection regimes I. E. , the experimental area, the buffer area and core area, respectively, each represented by 30 plots, in Nanling National Nature Reserve in Guangdong Province were studied. The results showed that: ( 1) 57 stems, 29 species in 23 genera and 15 families of standing dead trees were found in the 0.9 hm2 plot. Dominant families of the flora were Theaceae, Fagaceae, Euphorbiaceae, Lauraceae. The total of important value of Castanopsis fabric Hance, Pinus massoniana Lamb. , Castanopsis fargesii Franch. , Cinnamomum parthenoxylon (Roxb. ) Kost. , Pteroceltis tatarinowii Maxim, account for more than 60% of the whole important value. (2) There was significant difference in quantitative characters of standing dead trees under different protection conditions. It is difficult to conclude that quantitative characters of standing dead trees with higher protection are better. The experimental area with the least protection, had the least species richness, abundance, total basal area, and size-class structure of standing dead trees than the other two. The buffer area and core area with higher protection had uniform size-class structure of standing dead trees, while the total basal area of standing dead trees of buffer area was more than that of core area. (3)The analysis of multi-response permutation procedures (MRPP) and indicator species analysis (ISA) identified that standing dead trees had a significant influence on the community habitat. There were different indicator species under different protection conditions.关键词
