摘要
针对中国近年来由于土地资源需求量与外部环境压力增加而导致的土地利用急剧转型问题,以沿海城市闽侯县为例,综合利用遥感、地形和社会经济数据,从数量结构、转型幅度、转型速度、空间结构、效率与功能等显、隐性双形态方面分析了闽侯县土地利用转型情况。结果表明:显性形态方面,地势低、坡度缓、城镇工业化发展较迅速的街镇地区建设用地转型速度最快,年均增长率为8.74%,林地转型速度最慢,年均增长率为-3.62%。隐性形态方面,建设用地功能形态、耕地生产功能形态和对林地的投入是影响其用地类型转型的主要因素,闽侯县建设用地功能指数的线性增长,耕地生产指数不断上升和林业生产效益回升,不断影响土地利用形态的变化。研究成果可促进该区土地资源的可持续发展利用,为政府科学合理规划和强化土地集约节约利用效率提供决策支持。
Targeting the recent increase in land demand and external environmental stress in China leading to the dramatic land use transformation,Minhou County in China was used to investigate the land use transformation in the biconditional perspective of dominant and recessive,which were quantity structure,transformation magnitude,transformation speed,spatial structure,efficiency and function by the utilization of remote sensing,topography and socioeconomic data.The results show that in the study of the dominant form,the construction land transformation in the town industrialized developing rapidly with low-lying slope has the fastest speed,whose average annual growth rate is 8.74%,while the woodland moving to the lowest of-3.62%.In terms of recessive form,the results show that the functional pattern of construction land,cultivated land production and the input into woodland are the prime factors that impact the land use transformation.The linear growth of the functional index from the construction land,the rising production index of cultivated land and the rebound efficiency of forestry production in Minhou County in China have continuously influenced the variation of land use patterns.It is concluded that the findings of the research can promote sustainable development and utilization of land resources in the region,providing decision support to the government for scientific and rational planning and strengthening the efficiency of intensive land use.
