In order to understand the relationship between soil moisture and aboveground biomass of under- story vegetation in Robinia pseudoacacia forests in Loess hilly region,20 plots were sampled,including 16 Robinia pseudoacacia Forest plots at different age and 4 abandoned field plots over 25 years.

A method of fractal geometry was adopted to analytically study the relations between aboveground biomass and plant height of Aneurolepidium dasystachys populations.

The correlation analysis between tree morphological parameters and aboveground biomass was studied in March 1992 for an Avicennia marina community at Daguansha of Beihai pennisula of Guangxi.

Function y=ax~b maybe can disclose the correlation between shoot fractal structure and above-ground biomass of hungriness plant in Taklamakan Desert compared with Turpan Basin.

Based on 13- year observations, the annual response of the above-ground biomass of an Aneurolepidium chinense community to the seasonal changes in precipitation was analysed by establishing an integral regression model between the variable of biomass and the amount of precipitation for every 10 days from January to July.

The total aboveground biomass of lianas in the natural moist evergreen broad-leaved forest was 9.

The purpose of this study is to examine the effect of varying interspecific root interactions on the dry weight of shoot/root biomass and N-content in a split-pot arrangement experiment.
