【摘要】：伴随着城市化的发展,中国城市的生态问题也愈来愈加严重。经济的高速发展、人口的急剧膨胀、尤其是城镇土地的快速扩张,都对城市区域生态造成了巨大的压力。作为人类社会可持续发展的物质基础和自然资本,生态系统服务对人类的福利具有重要的不可替代性。因此,客观地认识城市化进程中流转土地的生态属性,对城市生态区域的生态系统服务价值(Ecosystem service value,ESV)进行评估并分析其变化与经济发展之间的关系具有重要的现实意义。本文从城市化进程中土地流转对生态系统服务价值的影响出发,以Costanza等人(1997)的研究为基础,以中国厦门市为例进行了ESV实例研究,研究结果表明:(1)在中国当前的土地管理体系下,土地流转时,考虑土地的生态属性能够减少社会的福利损失,体现了土地的生态价值。(2)厦门市在2002-2012年间的城市化引起了土地格局的巨大变化,进而导致了厦门市ESV呈现了先上升后下降的趋势,生态系统服务价值受经济发展影响显著。(3)厦门市的ESV与绿色GDP的变换呈现简单的反向关系,但是2003-2012年间厦门市的绿色GDP的正面效应很高。本文考虑了土地的生态属性,指出了厦门市保护湿地、森林、农田等生态系统的重要性和必要性,更进一步分析了生态系统服务价值与绿色GDP之间的关系,强调了生态环境与城市化的和谐发展。为城市化和生态的和谐发展提供了一个新的视角。
[Abstract]:With the development of urbanization, the ecological problems of Chinese cities are becoming more and more serious. The rapid development of economy and the rapid expansion of population, especially the rapid expansion of urban land, have caused great pressure on urban regional ecology. As the material foundation and natural capital of the sustainable development of human society, ecosystem service plays an important and irreplaceable role in human welfare. Therefore, it is of great practical significance to understand objectively the ecological attributes of land circulation in the process of urbanization, to evaluate the ecosystem service value of urban ecological regions and to analyze the relationship between the changes and economic development. In this paper, based on the study of Costanza et al.'s 1997) and the effect of land transfer on ecosystem service value in the process of urbanization, a case study of ESV is carried out in Xiamen, China, as an example. The results show that under the current land management system in China, considering the ecological attributes of land can reduce the loss of social welfare. The ecological value of land. (2) the urbanization of Xiamen City between 2002 and 2012 resulted in a great change of land pattern, which led to the trend of ESV rising first and then decreasing. The value of ecosystem services was significantly affected by economic development. (3) the transformation of ESV and green GDP in Xiamen showed a simple reverse relationship, but the positive effect of green GDP in Xiamen from 2003 to 2012 was very high. In this paper, the ecological properties of land are considered, and the importance and necessity of protecting wetland, forest and farmland in Xiamen are pointed out, and the relationship between ecosystem service value and green GDP is further analyzed. The harmonious development of ecological environment and urbanization is emphasized. It provides a new perspective for the harmonious development of urbanization and ecology.
