摘要: 探究生态环境基底脆弱的干旱区土地利用强度与碳排放的协同关系,对促进区域土地资源优化配置和实现“双碳”目标具有重要的现实意义。本研究基于2000年、2005年、2010年、2015年和2020年的土地利用和能源消耗数据,采用土地利用碳排放核算模型、协调度模型、未来土地利用模拟(Future Land Use Simulation,FLUS)模型和灰色预测模型,探究新疆和海拔1500 m以下区域的土地利用强度和碳排放的时空分异规律及协调发展水平,并模拟2030年4种情景下的演变趋势。结果表明:(1) 2000—2020年新疆土地利用强度指数增加3.2,新疆海拔1500 m以下区域土地利用强度指数增加4.5,增长速率高于全疆增长速率。(2) 2000—2020年新疆土地利用碳排放增加1.70×108 t,新疆海拔1500 m以下区域贡献率超95%,且碳排放高值区对低值区的侵蚀现象显著。(3) 2000—2020年新疆海拔1500 m以下区域协调系数始终高于全疆水平,其本质为“高开发-高排放”的粗放平衡。(4) 相关结果显示2030年在生态保护情景(Ecological Protection Scenario,EPS)下,可以通过生态用地扩容来实现开发与减排平衡;而在战略发展情景(Strategic Development Scenario,SDS)下,碳排放增量最大,反映出经济建设仍依赖能源消耗。研究结果反映新疆需进一步统筹经济建设与生态保护,才能有效实现可持续发展道路。

Abstract:

Exploring the synergistic relationship between land-use intensity and carbon emissions in arid regions with fragile ecological foundations is of practical significance for optimizing the allocation of regional land resources and achieving “dual carbon” goals. Based on land use and energy consumption data from 2000, 2005, 2010, 2015, and 2020, this study employs a land-use carbon emission accounting model, coordination degree model, FLUS model, and Gray Forecast Model to explore the spatiotemporal differentiation and coordinated development level of land-use intensity and carbon emissions in Xinjiang and areas with elevation <1500 m above sea level. Furthermore, the study simulates evolution trends under four scenarios in 2030. The results show that:(1) From 2000 to 2020, the land-use intensity index of Xinjiang increased by 3.2, whereas in areas with elevation <1500 m above sea level, it increased by 4.5, indicating a faster growth rate in these areas. (2) From 2000 to 2020, land-use carbon emissions in Xinjiang increased by 1.70×108 t, with more than 95% of the total emissions originating from areas below 1500 m. Moreover, high-emission zones exhibited a significant spillover effect on adjacent low-emission zones. (3) From 2000 to 2020, the coordination coefficient between land-use intensity and carbon emissions in areas with elevation <1500 m above sea level was consistently higher than that of the whole Xinjiang, although this primarily reflected an extensive balance of “high development-high emissions”. (4) Projections for 2030 indicate that under the Ecological Protection Scenario, a better balance between development and reduction in carbon emission could be achieved through the expansion of ecological land. In contrast, the Strategic Development Scenario would yield the largest carbon emission increment, reflecting continued economic reliance on energy consumption. These findings indicate the need for Xinjiang to further integrate economic development with ecological conservation strategies to effectively achieve sustainable development.
