摘要:
[目的] 研究黄河流域生产—生活—生态空间(简称“三生”空间)土地利用转型的结构、空间特征及其生态环境效应,定量权衡土地资源开发与生态环境保护之间的关系,为黄河流域的生态保护和高质量发展提供决策支持。[方法] 以黄河流域为例,利用ArcGIS空间分析与制图技术、生态环境质量指数和土地利用转型对生态环境的贡献指数等模型方法。[结果] ①2000—2020年黄河流域“三生”空间土地利用结构表现为生产用地面积减少,生态用地面积相对稳定,生活用地面积不断增加。②2000—2020年黄河流域生态环境质量指数分别为0.450 2,0.450 5和0.456 7,呈稳定上升趋势。③2000—2020年黄河流域生态环境质量指数在空间分布上有明显的差异性,表现为由东南向北部递增。④2000—2020年黄河流域牧草生态用地对流域生态环境质量贡献率最高。20 a间黄河流域生态环境存在改善和恶化两种趋势,前者大于后者,流域生态环境不断改善。[结论] 城乡生活用地和工矿生产用地对农业生产用地的占用是黄河流域生态环境恶化的主要因素,应合理规划“三生”空间,优化国土资源空间配置,落实黄河流域生态保护和高质量发展国家重大战略。

Abstract:
[Objective] The land use transformation structure, spatial characteristics and ecological environmental effects of the production-living-ecological space in the Yellow River basin were studied, in order to balance land resource development and ecological environmental protection, and provide decision-making for the ecological protection and high-quality development of the Yellow River basin. [Methods] Taking Yellow River basin as the study area, the land transformation was analyzed by using spatial analysis and mapping functions of ArcGIS platform, ecological environment quality index and the contribution index of land use transition to the ecological environment. [Results] ① From 2000 to 2020, the land use structure showed that production land area was decreasing, ecological land remains relatively stable and living land area was increasing. ② In 2000, 2010 and 2020, the eco-environmental quality index of the Yellow River basin was 0.450 2, 0.450 5 and 0.456 7 respectively and showed a stable upward trend. ③ There were obvious differences in the spatial distribution of the ecological environment quality index from 2000 to 2020, and the overall trend was increasing from the southeast to the north. ④ From 2000 to 2020, forage ecological land contributed the most to the ecological environment quality of the Yellow River basin. In last two decades, there existed two trends of deterioration and improvement of ecological environment, and the latter was more than the former. Consequently, ecological environment of Yellow River basin had been improved. [Conclusion] The occupation of agricultural production land by urban and rural living land, and industrial and mining production land is the main factor that caused eco-environmental deterioration in the Yellow River basin. The decision makers should rationally plan the production-living-ecological spaces and optimize the spatial allocation of land resources, so as to promote the major national strategy for ecological protection and high-quality development in the Yellow River basin.
