Abstract: Land degradation is a consequence stemming from both natural
processes and social economic activities. On the bases of analyzing general
situation of agricultural land degradation in China, the monetary estimating
methods such as market value method and shadow engineering method were used to
quantitatively assess the economic loss resulting from land deterioration.
Results showed that the economic loss in 1999 was 326.81 billion RMB Yuan,
which accounted for 4.1% of GDP in the same year of China. If taking five items
namely farmland conversion, soil erosion, salinization, decline in reservoir
functions, and siltation in waterways and, comparing withthat in 1992, the
percentage of economic loss to GDP has increased by 1.5 in the only 7
years.
