| 摘 要： | 为了研究土地利用对生态服务价值(ESV)的影响,基于中国地级及以上城市1990—2018年土地利用和社会经济数据,采用土地利用动态度、ESV评估模型、敏感性指数和空间自相关等方法,对研究区土地利用和ESV的时空分异特征进行了研究,分析了ESV与综合土地利用动态度、社会经济指标的空间相关性。结果表明:整体而言,除草地面积减少外,其他用地类型均有增加,各用地类型的动态度存在明显差异,综合土地利用动态度随年份有所增加; 研究期内,ESV总体上呈减少趋势,不同土地类型生态服务价值敏感性指数均<1; 研究期内生态服务价值变动与综合土地利用动态度呈负相关,各年份生态服务价值与社会经济指标综合值的双变量LISA图空间特征较为一致,低—高型主要分布于经济发展较快的中、东部地区,高—低型则主要分布于草地面积广泛、经济发展较为落后的西部地区。不同用地类型和社会经济因素对不同区域ESV影响具有一定差异,可为实现中国促进区域环境保护和经济可持续发展提供更加科学的决策服务。

| Abstract: | In order to study the impact of land use on ecological service value(ESV), based on the land use and socioeconomic data of Chinese prefecture level cities from 1990 to 2018, the temporal and spatial differentiation characteristics of land use and ESV in the study area were studied by using the methods of land use dynamics, ESV evaluation model, sensitivity index and spatial autocorrelation, and the relationship between ESV and comprehensive land use dynamics spatial correlation of socio-economic indicators were analyzed. The results showed that: on the whole, except for the decrease of grassland area, other land use types increased, the dynamic degree of each land use type was significantly different, and the dynamic degree of comprehensive land use increased over the years; during the study period, ESV generally showed a decreasing trend, and the sensitivity indexes of ecological service values of different land types had been shown as <1; during the study period, the change of ecological service value was negatively correlated with the dynamic degree of comprehensive land use; the spatial characteristics of bivariate LISA map of ecological service value and comprehensive value of socio-economic indicators in each year were relatively consistent; the low—high type mainly distributed in the middle and eastern regions with rapid economic development, while the high—low type mainly distributed in the western regions with extensive grassland area and relatively backward economic development. Different land types and socioeconomic factors have different effects on ESV in different regions, which can provide more scientific decision-making services for promoting regional environmental protection and sustainable economic development in China. |
