Source: State Land Administration, Statistical Information on the Land of China in 1995. Beijing, 1996. And equivalent reports for 1988 to 1994.
Note:"Construction" (column 4) includes all kinds of infrastructure, industrial areas and residential areas.  In the original data tables this category includes all construction by state-owned units (cities, towns, mining and factories, railways, highways, water reservoirs, public buildings) and constructions by rural communities (rural roads, township and village enterprises, rural water reservoirs, offices, education and sanitation, rural private resident housing).
Cultivated land-use change is quite unevenly distributed among China's provinces. The largest net-change was reported from Shaanxi - it contributed 21 percent to the overall net-decline of 1,722 thousand hectares between 1988 and 1995.
Most of the land reclamation in China was reported from Xinjiang, Yunnan, Inner Mongolia and Heilongjiang (each of these province contributed between 10 and 14 percent). Cultivated land increase through drainage was mostly done in Guangdong and Jilin. From all Chinese provinces Hebei reported most of the re-use of abandoned land (17 percent of the overall increase). Cultivated land increase through re-conversion from other agricultural land was mostly reported from Yunnan (18% of the national total).

It is interesting that land-loss due to construction of infrastructure, settlements and industries is quite equally distributed among the Chinese provinces. The largest contribution to the overall decline was from Jiangsu province which contributed 8.4 percent to the total.
