- Abstract:
-
Several study methods including land use dynamic index (LUDI) and regional differentiation index (RDI) of the cultivated land, environment-income curve (EIC), economic theory, grey relationship analysis (GRA), principal component analysis (PCA) and multiple regression analysis (MRA) were applied to study the changes of the cultivated lands and their driving forces in Qingdao city during 2000—2009. It was obvious that the rate of changes of the cultivated lands switched from a higher level (LUDI -0.106 during 2000—2003) to a lower one (LUDI 0.014 during 2006—2009). Urbanization, economic construction and industrial structure were the main driving forces during this period. The results also showed that the changes of the cultivated lands in Qingdao city had a remarkable regional differentiation and phasic characteristics. The phase transition of the cultivated lands usually lagged about 1 or 2 years behind the phase transition of the analog industrialization due to the impact of the inertia of economic development. However, the curve of relationship between cultivated land changes and per capita GDP showed an inverted ‘N’ shape, which was different from previous study results. Furthermore, industrial structure and population urbanization were the direct and pervasive influence factors of cultivated land changes respectively.
