The experiment was conducted on the 8-year-old Taxodium stand network in Pearl River delta; the accumulation, return and release of the main 7 nutrient elements (N, P, K, Ca, Mg, Na, Cl) of the network ecosystem were measured.

Storage of Dead Woods and Effect of Dead Woods on Regeneration of PICEA-Fir Forest in Changbai Mountains;

In order to enrich research of coarse woody debris and discuss ecological functions of coarse woody debris in the course of Picea schrenkiana natural regeneration,this paper focuses on the study of storage,decomposition dynamics and nutritious content of CWD in Picea schrenkiana-Dryopteris filix-mas stand in the Western Tianshan Mountains National Nature Reserve by the method of temporary sample.

Composition and carbon storage of woody debris in moist evergreen broad-leaved forest and its secondary forests in Ailao Mountains of Yunnan Provinve;

Measuring and calculating method of forest carbon storage.;

Study on the carbon storage and distribution of Pinus massoniana Lamb plantation ecosystem at different growing stages;

The results showed that:1)with moisture content increasing, the decreasing extent of wood storage modulus extended with temperature increasing;2) two mechanical relaxation processes were observed in this study.
