摘要
【目的】以河北省邯郸市为例,研究资源型城市耕地资源的时空变化过程,为该区域土地资源合理利用提供理论依据。【方法】利用邯郸市1990、2000、2008年遥感影像、耕地调查资料及社会经济统计数据,分析邯郸市耕地非农化的时空变化特征,并利用转移矩阵进一步探讨邯郸市耕地与其他土地利用类型之间的转化关系;最后通过灰色关联分析,探讨2000-2010年来邯郸市耕地非农化的影响因素。【结果】1990-2010年,邯郸市耕地非农化面积在时间上呈现一定的波动性,在空间上表现出很强的地域性,城市中心耕地非农化程度最高,耕地非农化程度从市中心向外呈现先增加后降低的趋势,先后出现耕地缓慢非农化区、耕地增长区;转移矩阵分析表明,耕地转出量大于转入量,耕地面积呈减少趋势;最后经过灰色关联分析得出,人口因素、农民人均收入水平、科技水平、第三产业是影响2000-2010年邯郸市耕地非农化的主要因素。【结论】资源型城市耕地非农化问题日益严重,促进其耕地资源合理非农化,对保障该区域经济健康发展和社会稳定有重要意义。
This study was conducted to analyze land use/land cover changes of space-time pattern in resources based cities in Hebei Province.Handan city was discussed as an example.【Method】This paper took advantage of remote sensing images and cultivated land and socioeconomic data from 1990 to 2010 to study the spatial and temporal variations of cultivated land conversion in Handan City.The transfer matrix analysis was used to further explore the transformation relationships between cultivated land and other land use types,and gray relational analysis was used to investigate the affecting factors on cultivated land conversion affecting factors in last ten years.【Result】From 1990 to 2010,cultivated land conversion of Handan showed fluctuation and regionalism.The conversion ratio in city center was the highest and it increased initially（cultivated land area）followed by decrease（cultivated land growing area）fromthe city center to outward of the city.Transfer matrix analysis showed the reduction of cultivated land was greater than the increase with the total cultivated land decreased.Gray correlation analysis method showed that demographic factors,income per capita levels of farmers,the development of science and technology,the development of tertiary industry were the main factors affecting cultivated land conversion in Handan City from 2000 to 2010.【Conclusion】Cultivated land conversion is getting worse in resources-based cities.Promoting the cultivated land conversion reasonably is important to guarantee the healthy development of regional economy and social stability.
