STUDIES ON THE FOREST SUCCESSION IN DALAO RIDGE, HUBEI PROVINCE
|
Abstract:
This paper is aimed to determine the forest successional trends based on the analysis of forest size structure in Dalao Ridge, Western Yichang, Hubei Province. The data were collected from nine community types. According to the observation in the field, the dominant species are Betula luminifera, Quercus glandulifera var. brevipeliolata, Quercus glandulifera var. glanduligera, Castanea henryi, Castanea seguinii, Carpinus fargesii.According to the size structure analysis, it is clearly that betula sp. is a "pseudo-pioneer species" in the Ridge, and will be replaced by Quercus spp. and Castanea spp. in the future, The climax communities in the Ridge are Comm. Quercus glandulifera var. brevipetiolata. Comm. Quercus glandulifern var. glanduligera, comm. Castanea seguinii, respectively.In a word, the forest size structure analysis is an effective way to study the trend of vegetational succession.
