It can be seen from Tab.3 that the conversion process took place 
mainly between cropland, woodland, grassland and built-up land, 
Thereinto, the conversion from cropland to urban land is the 
most dominating. This illustrated that urban expanding took use 
of a lot of cropland. In addition, some urban land was converted 
to water area, which was caused by the Three Gorges dam 
sluicing and nearby town submerged. It is obvious that the 
increase of construction land and water area is at a cost of the 
decrease of cropland, woodland, grassland. 
1) All the above analyses have shown that the land use and land 
cover status in Three Gorges Reservoir Area have changed 
significantly in the recent 30 years. Cropland, woodland, 
grassland decreased continuously, at the same time, water body 
and built-up areas increased obviously. 
2) Build-up areas increased continuously, and the increasing 
speed had being enhanced based on a bigger number, it arrived 
at the biggest 2.894% in 1995-2000 period, which were at the 
cost of cropland, woodland, grassland. 
3) In 2000-2005 period, water body increased most quickly by 
1.918% on the dynamic degree of change at the expense of 
woodland, grassland and even built-up areas, as a result of three 
gorges dam built. 
4) The research also released that the land use changes in Three 
Gorges Reservoir Area are drived by two main forces: one is the 
growing population with the non-agriculture population scale 
enlarging, another is the constructing Three Gorges Project, 
which brought migration moving, land submergence, and 
accelerated the regional economy, leading to the rapid rise in the 
use of construction land.
