- Abstract:
- Land use/cover change (LUCC) is one of the most important factors that effect ecological, hydrological processes and thus the ecosystem services at watershed and regional scales. Analysis on spatial structure characteristics of LUCC is the basis to develop adaptive watershed management strategies. Land use/cover data in the Chaohe River basin from 1979 to 2009 were interpreted from Landsat remote sensing satellite images and built by GIS and RS. In addition, the dynamics of land use/cover changes was quantitively explored, and its driving force was deeply discussed from the two aspects of nature and human. Results showed that the woodland, shrubland and grassland were the main land use/cover types in the basin. Compared with the data of 1979, in 2009, arable land and grassland decreased sharply, accounting for 6.31% and 13.28% of the basin area, respectively. Shrubland and woodland increased dramatically, accounting for 41.76% and 36.26%. Construction lands increased, accounting for 0.98%. Unused land and water body reduced to 0.27% and 1.14%, respectively. Arable land has been mainly converted to the grassland and shrubland. Grassland has been shifted into shrubland and woodland. Shrubland and woodland were transformed reciprocally. The increase of construction land mainly originated from arable land.
