Abstract

The land system faces many pressures from the provision of biomass resources and space to the economy. The need to understand land use and cover changes and its drivers is of high importance. This work presents an innovative approach by applying a transdisciplinary approach combining the methods of spatial analysis Land Cover Flows with the methods from the concept of socio-economic metabolism, Material and Energy Flow Accounting, Human Appropriation of Net Primary Production (HANPP) and Final Energy Return on Investment (FEROI). Our main aim is to identify the main land use changes and land cover flows, link them to the underlying socio-economic processes and interpret them in a historical context. Our results show that the overall land use intensity is growing although the positive trends of growing grasslands and forests started after the collapse of communism. The growing intensity of agricultural production with increasing suburbanisation reversed these trends. Until the 2000s the HANPP decreased but at the end of the period increased from 55 % in 2012 to 70 % in 2018. Volumes of the extraction of agricultural biomass are growing while the area of agricultural land has decreased. FEROI grew and stabilised to around 1.0 in the last period (2012–2018) comparable to the value found in the year 2001. The suburbanisation rates peaked after the year 2000 at 250 m²/km²/yr.

后共产主义捷克三十年的土地覆盖流量和土地利用强度:变化趋势和驱动力

土地系统面临着从提供生物质资源和空间到经济的许多压力。了解土地利用和覆盖变化及其驱动因素的必要性非常重要。这项工作提出了一种创新的方法，将空间分析土地覆盖流的方法与社会经济代谢、物质和能量流核算、净初级生产的人力分配（HANPP）和最终能源投资回报（FEROI）概念的方法相结合。我们的主要目标是确定主要的土地利用变化和土地覆盖流量，将其与潜在的社会经济进程联系起来，并在历史背景下对其进行解释。我们的研究结果表明，尽管草原和森林的积极发展趋势始于共产主义垮台之后，但总体土地利用强度仍在增长。随着郊区化程度的提高，农业生产强度的提高扭转了这些趋势。直到21世纪初，HANPP一直在下降，但在这一时期结束时，HANPP从2012年的55%上升到了2018年的70%。农业生物量的开采量在增长，而农业用地面积却在减少。FEROI在上一个时期（2012-2018年）增长并稳定在1.0左右，与2001年的数值相当。郊区化率在2000年后达到峰值，为250平方公里/年。

期刊介绍： Anthropocene is an interdisciplinary journal that publishes peer-reviewed works addressing the nature, scale, and extent of interactions that people have with Earth processes and systems. The scope of the journal includes the significance of human activities in altering Earth’s landscapes, oceans, the atmosphere, cryosphere, and ecosystems over a range of time and space scales - from global phenomena over geologic eras to single isolated events - including the linkages, couplings, and feedbacks among physical, chemical, and biological components of Earth systems. The journal also addresses how such alterations can have profound effects on, and implications for, human society. As the scale and pace of human interactions with Earth systems have intensified in recent decades, understanding human-induced alterations in the past and present is critical to our ability to anticipate, mitigate, and adapt to changes in the future. The journal aims to provide a venue to focus research findings, discussions, and debates toward advancing predictive understanding of human interactions with Earth systems - one of the grand challenges of our time.
