摘要:

以塔里木河流域为研究区,基于Landsat遥感影像和社会经济数据,运用Flus-Markov模型和当量因子法,分析2012—2032年土地利用格局动态变化,评估生态系统服务价值(Ecosystem service value,ESV)的时空特征,进而预测其未来变化趋势。结果表明:(1) 2012—2032年未利用地和水域面积先减后增,耕地持续扩张,草地显著退化,导致ESV总量下降2093.72×108元,其中草地和水域贡献分别下降2984.17×108元和38.44×108元。(2) ESV空间分布呈现西北高、东南低特征,水文调节、气候调节及气体调节为关键服务功能。(3) 敏感性分析显示,水域和草地变化对ESV影响最大,但价值系数修正的弹性较低,表明估算结果稳健。模型验证显示Kappa系数达0.95,预测精度可靠。(4) 土地利用以及归一化植被指数是影响塔里木河流域生态系统服务价值的主要影响因子。研究揭示塔里木河流域生态服务功能退化与土地利用扩张的关联性,建议通过优化土地利用结构、强化草地和水域保护以提升ESV,为干旱区生态安全与可持续发展提供科学依据。

Abstract:

This research integrates the Flus-Markov model and the equivalent factor method to analyze dynamic changes in the land use patterns in the Tarim River Basin from 2012 to 2032, evaluate the spatiotemporal characteristics of ecosystem service value (ESV), and predict its future trends, based on Landsat remote sensing images and socioeconomic data. The results show that: (1) From 2012 to 2032, the area of unused land and water first decreased and then increased, while the cultivated land area expanded and grassland degraded significantly continuously, resulting in a decrease of 2093.72×108 yuan in the total ESV. The contributions of grassland and water decreased by 2984.17×108 yuan and 38.44×108 yuan, respectively. (2) The spatial distribution of ESV shows a significant gradient, decreasing from high values in the northwest to low values in the southeast. Hydrological regulation, climate regulation, and gas regulation are key service functions. (3) Sensitivity analysis shows that changes in water bodies and grasslands have the greatest impact on ESV. A low value of the elasticity of coefficient correction indicates that the estimation results are robust. Model validation reveals a Kappa coefficient of 0.95, indicating reliable prediction accuracy. (4) Land use and normalized difference vegetation index are the main factors influencing the ESV of the Tarim River Basin. This study reveals the correlation between the degradation of ecological service functions and increased land use in the Tarim River Basin. ESV could be improved by optimizing land use structure, strengthening grassland and water conservation, and providing a scientific basis for ecological security and sustainable development in arid areas.
