| Abstract: |
| With the advancement of China's ecological civilization construction, the production-living-ecological space, as the spatial carrier for human activities, has gradually become the core link for regulating the interaction between the human system and the natural environment. Especially in regions with complex landforms and fragile ecosystems, such as the gully areas of the Loess Plateau, the production-living-ecological spaces within the region are significantly constrained by natural conditions, and the ecological effects brought about by spatial evolution exhibit distinct regional particularities. Therefore, in the context of the comprehensive establishment of the national spatial planning system, analyzing and summarizing the research progress on the ecological effects of production, living, and ecological spaces at home and abroad can help to deeply understand the interaction mechanism of space and its impact on regional sustainable development, reveal the diversity and regularity of ecological effects at different regions and scales, and provide important references for the optimization of national spatial planning in ecologically fragile areas.
This study aims to comprehensively compare the research status and hotspots in the field of production-living-ecological space and its ecological effects at home and abroad. By using bibliometric tools such as Bibliometrix and CiteSpace, and by reviewing 1,000 English-language articles from the WOS database and 1,138 Chinese-language articles from the CNKI database from 1998 to 2023, an academic map of the ecological effects of the production-living-ecological space is drawn. Through the methods of co-citation network, keyword co-occurrence clustering, and trend analysis, the spatio-temporal evolution patterns of this field are revealed from three dimensions: research progress, method evolution, and practical application. In terms of research hotspots, foreign keywords focus on areas such as "land use, spatio-temporal changes in land use, ecosystems, and climate change", while domestic research started later and mainly focuses on " production-living-ecological space, ecological effects, national spatial planning, and spatial optimization". In terms of research progress, the intensity of cooperation, continuity, systematicness, and interdisciplinarity of foreign research are significantly higher than those of domestic research. The evolution process of foreign research has gone through static, dynamic to comprehensive integration stages, and multiple spatio-temporal scale comprehensive simulation models have been established; domestic research is more concentrated on single-scale studies, such as administrative units and geographical units.
The research findings are as follows: (1) International research has shifted from spatio-temporal changes in land use to human-land coupling systems under climate change, with biodiversity conservation and ecosystem service assessment becoming recent focuses; Chinese research follows three stages: "space identification - spatio-temporal evolution - ecological effect evaluation", which is highly consistent with the development of the national spatial planning system and environmental policies. (2) Research methods have broken through the limitations of traditional static data, gradually introducing high-resolution remote sensing images, multi-temporal historical land use data, and socio-economic statistics, enhancing the ability to identify the dynamic evolution of the production-living-ecological space. At the same time, by combining multi-scale modeling techniques, simulation frameworks suitable for different spatial scales have been constructed, achieving refined analysis from spatial pattern identification to ecological effect evaluation, significantly improving the timeliness and practicality of research. (3) Practical applications show a deepening feature of "single-space control - dynamic process simulation - focus on special geographical units", and the collaborative research on human-land relations in special geographical units such as river basins is becoming a future trend. How to construct a three-dimensional collaborative analysis framework of "topography - hydrology - human activities" in typical geographical units such as river basins and form a research paradigm for the collaborative mechanism of human-land relations in special geomorphic areas is becoming a frontier direction in national spatial planning optimization.
Based on the above research results, this study offers some suggestions for future research and practice. (1) Future research should establish an integrated research system, link land use with ecological impacts, and achieve more proactive spatial governance under climate change and human interference. (2) Future research should explore the establishment of an ecological effect evaluation index and a collaborative mechanism with the Loess Hilly Region Basin, and investigate the complex relationships among human, land, water and carbon elements in the basin system, in order to provide support for the research on spatial collaboration and the coupling of human-land relations. (3) Form a multi-scale comprehensive study. In the future, the Loess Hilly Region Basin can be considered as the research unit, and the related human-land-water-carbon elements can be selected to explore the interaction mechanism between the production-living-ecological space of the basin under different terrain-river system patterns and human activities and environmental changes, and propose collaborative management measures for the production-living-ecological space of the basin, striving to solve problems such as the collaborative linkage of multiple elements, dynamic collaboration at multiple scales, comprehensive integration of multiple models, and optimal simulation under multiple scenarios.
In conclusion, this study, by integrating relevant research results at home and abroad, provides a theoretical basis and practical guidance for optimizing spatial management in ecologically fragile areas in China. The research results not only deepen the understanding of the human-land system, but also provide a scientific benchmark for the optimization of territorial space and the formulation of ecological protection policies in China and even the world. |
