土地城市化减少了自然生态系统资产的面积。但是，随着社会经济的发展，自然生态系统资产的质量是否会得到提高？如果综合考虑自然生态系统资产面积和质量的变化，城市化对自然生态系统资产的主导影响是正面的还是负面的？对京津冀城市群快速城市化过程中生态系统资产的面积、格局、质量和总体状况进行了详细研究。分析了城市化对生态系统资产总体状况的影响。用于生成生态系统资产的统计、核算和分析的研究方法包括ArcGIS、卫星遥感图像、R语言编程和其他数据分析工具。研究结果表明：（1）除农田和湿地外，生态系统面积以退化为主，景观格局日趋破碎化。(2)但自然生态系统资产质量明显提升，自然生态系统资产总体状况得到优化。(3)除人口城镇化率外，人口密度、土地城镇化率和单位面积GDP的增长对自然生态系统资产总体状况也产生了重大负面影响。这提醒人们，资产质量的提高可以在一定程度上弥补面积的减少，除了人口城市化率外，还应适当控制人口密度、土地城市化和经济密度的水平。
Land urbanization has reduced the amount of area for natural ecosystem assets. However, with the development of the social economy, will the quality of natural ecosystem assets be improved? If one comprehensively considers the changes in the area and quality of natural ecosystem assets, is the dominant impact of urbanization on natural ecosystem assets positive or negative? In this study, detailed research is conducted on the area, pattern, quality, and overall situation of the ecosystem assets in the Beijing–Tianjin–Hebei urban agglomeration during the rapid urbanization process. The impact of urbanization on the overall situation of ecosystem assets is also analyzed. The research methods used to generate statistics, accounting, and analysis of the ecosystem assets include ArcGIS, satellite remote sensing images, R language programming, and other data analysis tools. The research results show that: (1) The ecosystem area was dominated by degradation, and the landscape pattern became increasingly fragmented, with the exception of farmland and wetland areas. (2) However, the quality of the natural ecosystem assets was significantly improved, and the overall situation of the natural ecosystem assets was optimized. (3) In addition to the population urbanization rate, the growth in the population density, land urbanization rate, and GDP per unit area had a significant negative impact on the overall situation of natural ecosystem assets. This reminds people that the improvement in asset quality can compensate for the reduction in area to some extent, and, in addition to the population urbanization rate, the levels of population density, land urbanization, and economic density should be appropriately controlled.
