摘要: 基于中国南方8省区喀斯特地区卫星遥感和地面气象观测资料,分析气候变化背景下中国南方喀斯特地区2000—2011年间的NPP时空变化规律,及不同土地利用类型NPP变化。结果表明: 在气候变化背景下, 2000—2005年间,研究区NPP值总体呈上升趋势,在2005年发生转折, 2006—2011年间,NPP值总体呈下降趋势; 喀斯特地区NPP的变化幅度明显大于非喀斯特区; 农田、低密度灌木林、混合用地等土地利用类型对石漠化反应敏感。

Abstract: Based on remote sensing and ground meteorological observation data, this article analyzes the temporal and spatial variation pattern of the net primary productivity (NPP) in the karst area of eight provinces in the southern China from 2000 to 2011 under the background of the climate change, and the NPP variation in different land use types. The results showed that under the climate change background, the region NPP showed an ascendant trend during 2000-2005, and there was a turning point in 2005; During 2006-2011, the region NPP showed declined; The change amplitude of NPP in the karst region was significantly greater than other landforms; Farmland, low density shrubbery, mixed land and other land use types were sensitive to rocky desertification. This study would provide a thought in risk evaluation of the karst rocky desertification, and provide a scientific basis for the ecosystem environment risk management.

Key words: climate change, NPP, land use, rocky desertification, karst region
