【摘要】：合理的土地利用配置,是解决城市发展与用地紧张矛盾的基础,随着城镇化和工业化的深入推进,建设用地的需求将快速增长。长乐市作为福州新区、福建改革开放沿海经济区的一部分,其发展体现了福建省沿海地带经济发展方式的特点,长乐市的土地利用态势在未来的发展中势必将发生大幅变化,而土地利用状况的变化,在一定程度上映射出了土地利用方式作为一种经济综合体发展的成果的体现,在土地资源有限供给与快速城镇化扩展对土地需求的矛盾上,研究长乐市在快速城镇化的背景下的土地利用变化规律,并进行未来发展的土地利用变化的预测,可以为区域地方经济建设和土地管理部门提供重要参考。基于统计分析模型的马尔柯夫模型在县域单元上应用较多,但是由于传统的马尔柯夫模型在实践中多是只是以简单的转移矩阵来作为进行计算依据,而对于原有的GIS信息利用不足,使得进行模拟只体现出一个宏观指标,而没有落实到具体空间上,因此本文在此基础上进行了扩展,将土地利用的空间动态变化利用GIS结合领域单元的概念进行空间模拟。首先,基于DEM和遥感图像对长乐市土地利用状况进行解译,通过面向对象的遥感解译方法,建立分类规则集,提高遥感影像解译效率,部分解决常用的监督分类方法在高分辨率信息自动提取解译上的低效问题；其次,参照长乐市近30年的统计资料及历史发展状况,对长乐市的土地利用时空分异进行分析；最后,基于马尔柯夫模型对长乐土地利用变化的预测,并结合领域单元的理念,对长乐市的土地利用空间动态变化进行模拟,从而将土地利用变化映射在地理空间上,促进马尔柯夫方法的空间化应用。
[Abstract]:Rational land use allocation is the basis to solve the contradiction between urban development and land use tension. With the further development of urbanization and industrialization, the demand for construction land will grow rapidly. As a new area of Fuzhou and part of Fujian's economic zone of reform and opening up, the development of Changle City reflects the characteristics of the economic development mode of the coastal zone of Fujian Province. The land use situation of Changle City is bound to undergo significant changes in the future development. The change of land use condition, to a certain extent, reflects the achievement of land use mode as a kind of economic complex development, and the contradiction between the limited supply of land resources and the rapid urbanization and expansion of land demand. The study on the law of land use change in Changle city under the background of rapid urbanization and the prediction of land use change in the future can provide an important reference for the regional economic construction and land management department. The Markov model based on the statistical analysis model is widely used in the county unit, but the traditional Markov model is based on the simple transfer matrix in practice. But for the original GIS information is insufficient, so that the simulation only reflects a macro index, but not the implementation of the specific space, so this paper expanded on this basis, The spatial dynamic change of land use is simulated by GIS combined with the concept of domain unit. First of all, based on Dem and remote sensing images, the land use in Changle City is interpreted. Through object-oriented remote sensing interpretation method, the classification rule set is established to improve the efficiency of remote sensing image interpretation. It partly solves the inefficient problem of automatic extraction and interpretation of high-resolution information by the commonly used supervised classification methods. Secondly, according to the statistical data and historical development of Changle in recent 30 years, the space-time differentiation of land use in Changle is analyzed. Finally, based on the Markov model to predict the land use change in Changle, combined with the concept of domain unit, the paper simulates the dynamic change of land use space in Changle city, so that the land use change can be mapped to the geographical space. The spatial application of Markov method is promoted.
