- Abstract:
-
Based on the land use status map of Yangling in 1989, and the on-spot inspection data in 2007 and 2013 according to the visual interpretation of aerial photographs of 2004 and 2010, we established land use information database of three periods with ArcGIS 10.0 system, and took multi-agent interviews survey of land use and economic income of 233 farmer households, then analyzed the land use dynamic change characteristics and its driving forces over the past 24 years. The results showed that in the period from 1989 to 2013, agricultural land area decreased by 2 351.36 hm2, construction land increased by 2 113.91 hm2 in Yangling. The agricultural land reduction was mainly due to the loss of the cultivated land. The cultivated land reduction mainly shifted to the construction land. Next was the land internal transfer in the agricultural system, it transferred to the orchard, the nursery and animal farm land. For the cultivated land, high rate of land changed from cereal crop land to facility-cultivated land. The main driving forces of land use changes were the policy regimes and socio-economic factors. Yangling is an agricultural town, it got some special policies from the central government, which directly guided land transfer and land use structure changes. And economic development and urbanization also accelerated the process, i.e., land use transferred from the low to the high-value products. Agricultural land changes in Yangling were in recession, especially for the cultivated land. To maintain the special status for agricultural town, the scientific coordinated relationships between protecting farmland and meeting the urban-rural construction land demands is necessary.
