摘要:

1985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

关键词: 环渤海地区, 土地利用变化, 驱动机制, 人口, 农业经济增长, 城市化

Abstract:

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.

Key words: Bohai Rim, land use change, driving force, population, agroeconomic development, urbanization
