According to remote sensing data, 30% of the total land area in terms of use patterns had changed in Bohai Rim during 1985-1995.Cultivated land change was the most important type, which was mainly transformed to rural dwelling land, forest, grassland, urban land, orchard and water area. Based on the analysis of cultivated land transformation and its relation between population and agroeconomic development, this article clarifies that land management policy, increase of per capita living space, adjustment of agricultural production structure and urbanization are the major driving forces of land use change in the region. Among the driving forces, the land management policy, especially the policy for cultivated land preservation was the most important factor that affected the regional land use change which facilitated the transformation of other land-use types into cultivated land through balancing those occupied. Population growth did not necessarily bring the increase of cultivated land. The even lesser cultivated land through improving crop yield could still satisfy the increasing demand for food. Population growth, variation of population density had no crucial affection on land use change but the increase of per capita living space could exert greater impact on regional land use change. Agroeconomic development incurred the adjustment of production structure and made cultivated land be transformed to orchard, water area and forest/grass land with the consideration of ecological environment. Urbanization drove land use change in aspects of both cultivated land quality and level of labourers.

198 5到 1995年间 ,环渤海地区占总面积 30 %的土地发生了利用方式的变化 ,耕地变化是其核心类型。耕地变化的主要流向依次为农村居住用地、林草地、城市居住建设用地以及果园和水域。本文通过对耕地流向及其与人口变化、农业经济发展的关系等进行分析 ,确认土地管理政策、人均居住用地的增长、农业生产结构调整以及城市扩张是该区土地利用变化的主要驱动因素

Based on the land-use datum (at scale of 100 000) of the interpretation of Landsat Thematic Mapper in 1980, 1995 and 2000, this study presents land-use change in Loess Plateau of Dingxi Prefecture, such as range, spatial distributing pattern, direction, farmland key change and development trend of land use pattern in 2015, by the combined using geographic information systems (GIS) method and Markov Probability Model. The results show: the annual rate of land-use change from 1995 to 2000 is 2.57 times as much as that from 1980 to 1995. In the period of 1995~2000, transformations of land-use pattern reveals obvious differences of spatial distributing pattern. Land-uses of farmland, grassland, woodland and rural resident land are the key change types. Transformations between farmland and other land-use patterns distribute most extensively. Most high quality farmlands change into rural resident land. The area of farmland changed into rural resident land from 1995 to 2000 has been increased to 66.18%(1759 hm~2) as compared with that from 1980 to 1995. The areas of woodland and grassland converting to farmland are 17294 hm~2. By 2015, area and proportion of farmland, urban or build-up land and rural resident land will increase. The area and proportion of the woodland, grassland, water land and barren land will decrease.

运用GIS空间分析方法,以1980年、1995年和2000年LandsatTM影像的土地利用空间数据(1∶100000)为基础,分析了1980~2000年定西地区黄土高原各土地利用类型变化的幅度、空间分布特征、方向以及耕地的主要流向,并应用空间马尔柯夫概率模型对定西地区2015年土地利用格局进行了预测。结果表明:1995~2000年土地利用的年变化率是1980~1995年的2.57倍;1995~2000年土地各类型之间的相互转化在空间分布特征呈现明显的差异,耕地、草地、林地和农村居住用地是定西地区土地利用变化的核心类型,耕地与其他类型土地间的相互转化分布最广泛;优质耕地主要被农村居住用地扩展占用。1995~2000年耕地转向农村居住用地的面积比1980~1995年增长了66.18%(1759hm2);1995~2000年毁林草开荒的面积仍高达17294hm2。到2015年,耕地、城镇用地、农村用地面积和比例将增加,草地、林地、水域和未利用地面积和比例将下降。
