摘要: 基于GIS软件平台,参照中国陆地生态系统服务单位面积价值,采用转移矩阵方法和Costanza生态系统服务价值计算公式,并结合敏感度分析,探讨了济南市1989—2009年土地利用变化和生态服务价值的变化特征.结果表明: 1989—2009年,济南市建设用地面积增加99.65 km2,农田和绿地面积减少103.21 km2,减少面积的90.4%被建设用地所取代;研究期间的生态服务总价值持续下降,从256.22×106元下降到214.16×106元,减少42.06×106元,农田和绿地对研究区总体服务价值变化的影响最大.济南市在未来的城市发展和规划中,需更加重视自然资源保护,合理规划土地利用结构,保持生态系统的稳定与平衡,以实现人口、资源与环境的可持续发展.

Abstract: Based on the GIS software platform, referring to the China ‘Terrestrial ecosystem services per unit area value’, and by using transition matrix, Costanza evaluation formula, and sensitivity analysis, this paper studied the change characteristics of land use and ecosystem services value in Ji’nan City in 1989-2009. During the study period, the builtup area in the City increased by 99.65 km2, while agriculture land and green space reduced by 103.21 km2, 90.4% of which was taken by the built-up land. The total ecosystem services value decreased from 256.22×106¥ to 214.16×106 ¥, with a decrement of 42.06×106 ¥, mainly due to the decrease in the areas of agriculture land and green space. For the sustainable development of the population, resources, and environment in Ji’nan City, future urban planning should pay more attention on the natural resources protection, reasonable planning of land use structure, and maintenance of ecosystem stability and balance.
