In this paper, wet deposition of nitrogen in a small watershed of the Three Gorges Reservoir Area (TGRA) was investigated from 2004 to 2008. These results indicated that average TN concentration in rainwater was 2.02 mg L-1, which exceeded the threshold of eutrophication. TN concentrations were higher in the dry season than that in the wet season, but the wet season was the key period for N deposition...
In this paper, we proposed a new grey model (GM) to realize the predictions and analyses of GDP structure, population structure and primary energy consumption structure from year 2004 to 2010 based on the data from 1995 to 2003. The improved GM is obtained by the following procedure: first, statistical method of linear regression is integrated into GM to enhance prediction capability. Second, residual...
Viewing from three aspects of the objective factors, the policy influence and the dual economic structure, this paper begins with analyzing the changing process of the structure of domestic demand in China from the year 1999 to 2004. What the analysis concludes explains that the growth mode of `investment-leading' is non-sustainable. And it's concluded that the total demand has the problem of structural...
