中国是世界上人口最多的国家，略多于一半的人口仍然生活在农村地区。在过去的几十年里，快速的城市化和工业化显著地改变了农村地区的土地利用/土地覆盖格局，特别是在中国东部的大城市周围。山东半岛，一个传统的农业区，也经历了快速的城市化和工业化。分析该地区土地利用/土地覆被变化，特别是农用地的变化，有助于更好地了解政府政策与农民经济利益之间的相互作用。空间分析结果表明，由于城市化和工业化的影响，耕地和其他土地利用/土地覆盖类别发生了显著变化。最有可能的原因是政府政策的不断调整和农民经济利益的转移。这项研究的结果将有助于政府在不久的将来做出明智的决策，在保持足够的农业生产的同时，缓解城市扩张和工业发展。(C)2011爱思唯尔有限公司。保留所有权利。
China is the most populated country in the world with slightly more than half of the population is still living in rural areas. In the past couple of decades, rapid urbanization and industrialization have significantly changed the land use/land cover (LULC) pattern in rural areas, particularly those around the big cities in eastern China. Shandong Peninsula, a traditional agriculture area, also has witnessed rapid urbanization and industrialization. Analysis of land use/land cover change in this area, specially the change of agricultural lands, would help us better understand the interaction between government's policies and farmers' economic interests.This paper developed a method to extract single-cropping land, double-cropping land and other land use/land cover categories for 1978, 1999 and 2006 from seasonal variations in Normalized Vegetation Index (NDVI) during a crop calendar year. Spatial analysis results indicated significant changes of arable lands and other land use/land cover categories due to the urbanization and industrialization. The most possible reason is due to the continuous adjustment of government's policies and shift of farmer's economic interests. Results from this study would help government make wise decisions in the near future to mitigate urban sprawl and industrial development while maintain enough agricultural production.
