上海市土地利用变化及驱动力分析
|
Abstract:
上海市作为中国的经济中心之一，研究其土地变化驱动因素具有借鉴意义。本文通过GIS技术和主成分分析法，研究了上海市20年间的土地利用变化趋势以及土地利用变化的驱动力。结果显示：以经济增长和城市化为代表的社会经济发展和以农业生产为代表的初级产业对上海市的土地变化有着较强的驱动力。通过合理分配土地保护自然环境可实现对土地的永续利用，为未来的健康发展打下坚实基础。
As one of the economic centers of China, it is of great significance to study the driving factors of land change in Shanghai. In this paper, the trend of land use change and the driving force of land use change in Shanghai in the past 20 years were studied by GIS technology and principal component analysis. The results show that the socio-economic development represented by economic growth and urbanization and the primary industry represented by agricultural production have strong driving forces for land change in Shanghai. Through the rational allocation of land and the protection of the natural environment, the sustainable use of land can be realized, laying a solid foundation for the healthy development of the future.
