- Abstract:
- There was an obvious spatial difference in spatial patterns of land use in the water resource district of Middle-Route of the South-to-North Water Diversion Project because of the double effects of the terrain conditions and human activities. The spatial pattern of land use in study area was quantitatively analyzed by using DEM data. The results show that: (1) the land use types are mainly forestland, agricultural land and grassland, which shows that the matrix of landscape is forest;(2) the comprehensive index of land use is 221.19 in the water resource district in 2010, and this shows that land use intensity is relatively low in the water resource district with slight human-caused disturbance; (3) the spatial distribution rule of land use with the change of elevation and slope has notable characteristic, the agricultural land, construction land and water body in strongly human-disturbed land use types mainly distribute in lower altitude region and smaller gradient section. The forestland, grassland and unused land in slightly human-disturbed land use types are dispersed in higher altitude region and bigger gradient section equably.
