Taking the energy intensity into account,the non-residue complete decomposition model is applied to the quantitative analysis of the effects of three economically factors on the change in energy consumption in Liaoning PRC,i.

This paper makes an empirical study on the characteristics of Chinese energy intensity Divisia decomposition approach.

Based on the data of 14 industrial sectors from 1990 to 2000 in China and 11 OECD countries,this paper use the decomposition method of multiplicative logarithmic Divisia index to make an empirical analysis on energy intensity characteristics of these countries in order to explain the major factor for energy intensity evolution.

A method in which the relation between source density (or drainage density) and the threshold is used to produce an ideal drainage network is proposed.
