| 摘 要： | 利用2000年遥感影像进行土地利用分类，并与1995年土地利用矢量图进行GIS空间叠置分析，结合数理统计分析，判定石家庄市1995—2000年耕地变动的方向与类型，揭示了该区耕地变化的数量特征和空间变化特征，全面分析了影响耕地变动的经济、人口、政策等主要因素，并重点研讨了城市化进程与耕地变动的关系，阐明了石家庄市在目前城镇发展的初级阶段用地的基本特征与存在问题。石家庄市土地利用变化值得注意的两个特殊点是：石家庄市耕地占用的主要原因是建设用地占地(占耕地减少总量的52．3％，其次是农业内部调整占38％)，与全国农业内部调整为耕地减少的首要原因（占耕地减少总量的60％左右，建设占地30％左右)不同；在石家庄市非农建设占地中，独立工矿用地占了较大部分（40％)。 |

| Abstract: | Based on remote sensing images of 2000 and the land use vector map of 1995, through superposing and analyzing, we achieve the tempo-spatial process of land use change from 1995 to 2000 in Shijiazhuang City. By using data obtained from interpretation of remote sensing images and other statistical sources, we analyzed land use change patterns in Shijiazhuang City and their driving forces. The main conclusions include: (1) The main characteristics of the city's land use change are the obvious reduction of the cultivated land and the subsequent rapid increase of the constructive land, with the maximum increase of land area of single enterprise or mine land use type through taking up cultivated land. This shows a dissimilar pattern of cultivated land decrease with the whole country and some other regions. In China and the Bohai Rim, the main reason for cultivated land decrease is structural adjustment within agricultural sector. In Shijiazhuang City, the contribution of cultivated land decrease to structural adjustment in agricultural sector makes up only 38% of the total decrease, while that to occupation by construction land use makes up 52.3%. (2) As to spatial pattern, the cultivated land decrease in most counties of plain area and increase in few counties in mountainous area result from the exploitation and resuming cultivation of barren land. (3) Humanistic driving forces are the main reason for the cultivated land change in Shijiazhuang which include economic factor, population factor and policy factor. (4) The urban land use gives little help to the reduction of the cultivated land. Data show that the decrease of the cultivated land is inferior to the increase of urban level from which we know the use of cultivated land in Shijiazhuang is suitable. (5) At present, the urbanization process in Shijiazhuang is only in initial stages. About 2/3 of land use increase for non-agricultural use contributes to the occupation of township and rural enterprises. If there is no regulation and planning to control, land use for this purpose would be overdone. |
