The distribution of NEP in 2000 (Source: Data Centre for Resources and Environmental Sciences Chinese Academy of Sciences (RESDC)) Nutrient cycling and soil formation There is little available information on the nutrient cycling and soil formation services of terrestrial ecosystems in China. However, it has been widely acknowledged that the quality of soil has been reduced as a result of destructive land use practices, degradation of land, and the use of fertilizer on cropland ecosystems. This is particularly the case in grassland ecosystems, which are suffering from desertification at an increasing rate. The value of nutrient cycling for the terrestrial ecosystems of China was estimated to be RMB 324 billion yuan per year in 1995, whilst that of organic matter production has been estimated at RMB trillion yuan. The increasing rate per year and tendence of soil organic carbon can be seen below (Fig ). It showed nicely the loss of soil organic carbon from grassland areas and increase in the cropland '# ' Rale(%. vr ' ) â <= â â¢' â <- â <= â <= m< â¢;< y.
