a) Figures on land resources in the table were obtained from surveys in previous years. The figures are subject
to further verification. Figures on area of cultivated land were taken from the 1996's agricultural census. The
area of grassland was the figure of 1991's survey. Figures on area of afforested land and forest resources
were the figures of the Sixth National Forestry Survey (1999-2003). Total water resources volume and its
sub-item indicators are data in 2005, and other indicators in Water Resources were estimated figures in 1985.
