| Abstract: | Northeast China is an important agricultural region in China. The Northeast Plain is the largest plain in the country and
one of the three famous black soil zones in the world. Despite of fertility of the soil, however, large-scale agricultural
development mainly took place since 1900. The land exploitation and utilization has been fast and intensive in this region
since then and change in the land-cover process has been remarkable. Both national and international researchers on land use
and land cover are paying more attention to these processes in this region and their implication for local ecological environment.
This article discusses the land reclamation processes and their main driving forces in Northeast China since 1900. According
to the research, the 20th century was the most important period for land reclamation in Northeast China. In these years the
rate, intensity and quantity of land reclamation have been staggering, and more than 100 000km2 of land was converted into farmland. This magnitude of land reclamation inland is unique in the world. Research on the land
reclamation of Northeast China can provide some data on the effect of human activity on environment. As in many other places
in the world, the primary driving force of reclamation in Northeast China was the increasing pressure of population. In the
20th century the population increased from 10×106 to 110×106 in Northeast China and from 400×106 to 1.3×109 in China. Population pressure is thus the most important driving force for land reclamation.
