摘要:

研究“双碳”目标下“三生”空间时空演变特征及碳效应,对干旱区生态经济可持续发展及实现国土空间绿色低碳发展有重要的实践意义。本文基于新疆土地利用遥感监测数据和能源消耗数据,运用“三生”空间动态度、转移矩阵及碳排放系数等方法,借助ArcGIS空间分析功能对新疆2000—2020年“三生”空间时空演变特征及碳效应进行分析。结果表明:(1) 新疆近20 a“三生”空间综合动态度达0.11%,2005—2010年综合动态度最高。(2) 20 a间“三生”空间总体上呈现生活生产空间急剧扩张,生态空间面积缩减的趋势。(3) 生活生产空间是新疆最主要的碳排放空间类型,呈现出持续增长的趋势;生态生产空间对碳吸收的贡献率较大。研究结果可为构建符合新疆减排需求的“三生”空间分类体系提供科学支撑,对建设高质量“一带一路”,实现干旱区新疆低碳发展和“双碳”目标具有重要意义。

Abstract:

The study of the spatial-temporal evolution of the “production-living-ecological” space and the effect of carbon emission under carbon peak and carbon neutrality goals target is of practical significance for the sustainable development of ecological economies in arid areas and the realization of green and low-carbon development in land space. This study examined remote sensing monitoring data and energy consumption data for the Xinjiang in five periods: 2000, 2005, 2010, 2015, and 2020. Using the “production-living-ecological” spatial dynamic index, transfer matrix, and carbon emission coefficient, the spatial-temporal evolution characteristics and carbon effects of “production-living-ecological” in Xinjiang in the past 20 years were analyzed using the ArcGIS spatial analysis functions. The results show that: (1) the comprehensive dynamic index of the study area reached 0.11% in the past 20 years, with the highest from 2005 to 2010. (2) in the past 20 years, the area of the “production-living-ecological” space has changed greatly, revealing the rapid expansion of “living-production” space and declining trend in “ecological space”. and (3) “living-production” space is the main contributor to carbon emissions in the study area, and underwent continuous growth. In terms of carbon absorption, the contribution of the “ecological-production” space to carbon absorption is relatively high. The study provides scientific support for the construction of a spatial classification system for the “production-living-ecological” space that meets the emissions reduction needs of Xinjiang; thus, it is of great significance for the construction of high-quality “Belt and Road” and the realization of low-carbon development, carbon peak and carbon neutrality goals in arid regions.
