中国中越边境土地利用与生态效率的时空关联及其机制研究
Spatio-temporal correlation between land use and eco-efficiency and its mechanism along the Sino-Vietnamese border in China
摘要
Abstract
s:As the imbalance between the needs of human survival and development and the limited land use deepens,the Sino-Vietnamese border area faces multiple challenges such as population hollowing out,resource competition and ecosystem vulnerability.The article explores the land use and eco-efficiency values of the Sino-Vietnamese border region from 2010 to 2020 by using the super-efficiency SBM model and Tobit model,and systematically analyses the spatial and temporal evolution of the two values and their correlation mechanisms.The study finds that:the overall land use and ecological efficiency shows a significant trend of improvement,and most counties will reach super-efficiency in 2020;the two are spatially positively correlated and the correlation is getting stronger,and the area of high efficiency is expanding from the west to the east;among the influencing factors,the gross regional product and the vegetation cover index show a facilitating effect,and the investment in fixed assets,the growth of the population,and PM 2.5 concentration show an inhibiting effect;among the efficiency zones,the GDP and the vegetation cover index show an inhibiting effect;in the efficiency zoning,the land use and ecological efficiency of the border area are inversely related.Among the influencing factors,fixed asset investment,population growth and PM2.5 concentration show inhibitory effects;among the efficiency zones,the synergistic enhancement zone gradually expands,the double-low efficiency zone decreases,and the efficiency conflict zone shifts.In addition,the study reveals the correlation mechanisms of bidirectional positive feedback,bidirectional negative feedback,and short-term trade-off and long-term synergy between land use and ecological efficiency,which provides a scientific basis for realizing the synergistic optimization of the efficient use of land resources and ecological protection in the border area.The findings of this study are instructive for the study of border efficiency with differentiated spatial governance and synergistic development of ecological civilization regional construction to promote sustainable development along the border areas.关键词
