摘要
把灰色关联数学模型运用于区域耕地变化的驱动力研究之中,应用该模型对鄱阳湖地区1949～2002年不同阶段的耕地变化驱动力进行了分析,并结合不同的历史环境,确定了不同历史时期下影响耕地变化的各个驱动因子的关联程度和主次地位,以期为人们保护耕地,合理利用土地,实现鄱阳湖地区土地利用的可持续发展提供指导。
In this paper the Gray Connection Mathematical Model was utilized in the research on driving factor of the region farmland change.The cultivated land driving force in different stage of Poyang Lake area between 1949 to 2002 was analyzed.Combined with the different historical environment and the connection degree and the primary or secondary status of various cultivated land change driving force under the different historical period was confirmed.It expected to provide the instruction for protecting cultivated land,using land reasonably and realizing land utilization sustainable development in the Poyang Lake area.
