广西土地利用变化及其碳排放效应研究

Study on Land Use Change and Its Carbon Emission Effect in Guangxi

运用统计分析、对比分析等方法,对广西2007-2017年土地利用情况和碳排放量变化及其强度进行分析。结果表明,广西2007-2017年用地类型中建设用地面积增长最快,动态度达到3%。期间广西土地利用碳排放量整体呈现先增后减再增的趋势。建设用地作为广西土地利用碳排放的主要因素,其碳排放量最大,对碳排放的影响程度最强。因此,在日后发展过程中,政府需要提高建设用地的集约利用率,避免城市的盲目扩张,升级优化工业设备,加强在再生能源和低碳能源方面的开发力度,推动低碳经济发展。

Using statistical analysis, comparative analysis and other methods, the paper analyzes the land use situation, carbon emission change and intensity of Guangxi in 2007-2017. The results show that the area of construction land is the fastest growing in 2007-2017, with a dynamic degree of 3%. During this period, the carbon emission of land use in Guangxi showed a trend of increasing first, then decreasing and then increasing. Construction land is the main factor of carbon emission of land use in Guangxi. Its carbon emission is the largest, and its impact on carbon emission is the strongest. Therefore, in the future development process, the government needs to improve the intensive utilization of construction land, avoid the blind expansion of the city, upgrade and optimize industrial equipment, strengthen the development of renewable energy and low-carbon energy to promote the development of low-carbon economy.
