Abstract:

Land use and land cover change as the core of coupled human-environment systems has become a potential field of land change science (LCS) in the study of global environment change. Based on remotely sensed data of land use change with the spatial resolution of 1km ×1km on national scale among every five years, this paper designed a new dynamic regionalization according to the comprehensive characteristics of land use including regional differentiation, physical, economic, and macro-policy factors as well. Spatial pattern of land use change and its driving forces were investigated in Chia in the early 21st century. To sum up, land use pattern of this period was characterized by rapid changes in the whole country. Over the agricultural zones,e.g., Huang-Huai-Hai Plains, the southeast coastal area and Sichuan Basin, the built-up and residential areas were considerably expanded to a great proportion in the northwestern oasis agricultural zones and the northeastern zone led to a slight increase of arable land aea in the northern China. Due to the "grain for green" policy, forest area was significantly increased in the middle and western developing region,Where the vegetation coverage was substanially enlarged, likewise. This paper argued the main driving forces as the implementation of the strategy on land use and regional development, such as the "Western Development", "the Revitalization of the Northeast" policy, coupled with rapidly economic development during this period.

Key words: land use change, spatial pattern, driving forces, the early 21st century, China
