摘要:

人口系统是一个典型的灰色系统。根据1949—2005年望江县人口发展的最新统计资料,根据离散灰色增量模型,对未来望江县人口发展趋势进行预测研究,得出了望江县2010年和2020年的的人口预测值,并对该预测结果进行了精度检验与对比分析。通过与其他预测模型进行比较,反映了灰色预测模型具有较好的预测精度,有益于区域土地利用总体规划的制定。

Abstract:

Population system is a typical grey system. According to the latest statistical data of Wangjiang’s population development from 1949 to 2005, using discrete grey increment model, predict the population development of Wangjiang up to the year 2020. And the prediction results are tested and contrasted. Comparing with other models, the examination indicated that the improved gray model has good prediction precision. The model mentioned above will have certain values on the development of regional land-use general programming.
