摘要:

碳储量在陆地生态系统中扮演者重要角色,而土地利用变化是影响区域生态系统碳循环和储存功能的重要因素之一。以新疆为研究区,基于1980—2022年土地利用数据,耦合GeoSOS-FLUS和InVEST模型,分析了1980—2022年新疆土地利用和碳储量变化,并模拟了2030年和2060年在自然发展情景、生态保护情景和快速发展情景下的土地利用和碳储量变化。结果表明:(1) 1980—2022年新疆土地类型占比最多的为未利用地类,耕地、郁闭度<30%的林地、覆盖度>20%的草地、建设用地的总面积增加,郁闭度>30%的林地和灌木林、覆盖度<20%的草地、水域、未利用地面积减少。(2) 2030—2060年除未利用地之外,耕地和草地依旧是主要的土地利用类型。(3) 1980—2022年碳储量以2010年为节点,呈现先升高后降低的趋势,建设用地扩张和林草地退化、水域缩减是碳储量减少的主要原因。(4) 2030—2060年新疆地区碳储量高值区域主要分布在阿尔泰山、天山山脉和塔里木盆地北缘,生态优先情景高于自然发展情景和快速发展情景下的碳储量。研究结果有助于指导新疆地区土地格局调整与碳储存能力优化管理,对实现区域“双碳”目标具有重要意义。

Abstract:

Carbon storage plays an crucial role in terrestrial ecosystems. The change of land use is one of the key factors influencing the carbon cycle and carbon storage in regional ecosystems. This study focuses on Xinjiang as the research area, utilizing land use data from 1980 to 2022 and coupling the GeoSOS-FLUS and InVEST models to analyze the changes in land use and carbon storage in Xinjiang from 1980 to 2022. Additionally, the study simulates changes in land use and carbon storage under three scenarios, namely, the natural development scenario (DAU), ecological protection scenario (EPS), and rapid development scenario (RDS), for the years 2030 and 2060. The results show that: (1) From 1980 to 2022, unused land accounted for the largest proportion of land types in Xinjiang, and the total area of cultivated land, forest land with <30% canopy density, grassland with >20% coverage, and construction land increased. In contrast, forest land with >30% canopy density and woodlands, grassland with <20% coverage, water bodies, and unused land decreased. (2) Excluding unused land, during the period from 2030 to 2060, farmland and grassland remained the dominant land use types. (3) From 1980 to 2022, carbon storage initially increased, followed by a decrease, with 2010 as the turning point. The expansion of construction land, degradation of forest and grassland, and reduction of water bodies were the main contributors to the decline in carbon storage. (4) From 2030 to 2060, the high-value areas of carbon storage in Xinjiang were primarily distributed in the Altai Mountains, Tianshan Mountains, and the northern edge of the Tarim Basin. Under the EPS, carbon storage was higher than that under the natural development and rapid development scenarios. The research findings are expected to contribute to guiding adjustments in land use patterns and optimizing the management of carbon storage in the Xinjiang region, significantly facilitating the achievement of regional “dual carbon” goals.
