| Abstract: | Xiao Xing'an Mountains is main distributive area of forest marsh in China and has all kinds of forest marsh here. Based on a large amount of data, the distributive features of readily available nutrients of the marshland in Larix dahurica-Betula ovalifolia-Carex and Larix dahurica-ledumpalustre var. angustum-Sphagnum in the vertical profile in the different seasons are researched.The difference of two kinds of forest marsh and specific characteristics of all kinds of nutrients are set forth. The content and changing rules of readily available nutrients in the same type of marshland are also different because of different environmental conditions and stage of plants grownth. |
