基于灰色关联度的平顶山市耕地面积变化与经济增长关系分析研究

摘要

Based on the published data of the correlation between farmland area change economic growth in Pingdingshan from 1988 to 2012, this paper adopts the data of farmland area, GDP per capita, the proportion of the first industry in the GDP, the proportion of the second industry in the GDP and the proportion of the third industry in the GDP from 1988 to 2012 in Pingdings-han City.The grey relational degree analysis method and the comprehensive evaluation model are combined to construct a grey correlational degree analysis simulation which is used to analyze the relationship between farmland area change and economic growth.The results reveals that the third industry has the most significant influence on the area of farmland , followed by the sec-ond industry, the first industry and GDP per capita and the data collected provides an objective basis for the short-term planning for the long-term strategy of regional land use.%依据平顶山市1988年－2012年公布的耕地面积与经济增长关系数据，选取平顶山市耕地面积，人均生产总值，第一产业在生产总值中的比重，第二产业在生产总值中的比重，第三产业在生产总值中的比重作为分析因子，将灰色关联度分析方法和综合评价模型相结合，建立灰色关联度分析模型，对平顶山市耕地面积变化与经济增长关系分析。结果显示：第三产业最为影响耕地面积的变化，第二产业次之，第一产业再次之，人均GDP最小。能为区域土地利用的长期战略和短期规划提供依据。
