近日,贵州师范大学周忠发团队研究了中国喀斯特地区土地利用变化引起的生态干扰。2025年7月3日出版的《中国地理科学》杂志发表了这项成果。
土地主题变化是影响生态系统结构和功能的根本因素。
然而,很少有研究从结构与功能相结合的角度来探讨土地主题变化引发的生态干扰。研究组采用生态结构扰动指数(SDI)和功能扰动指数(FDI)对2009-2019年典型喀斯特地区——贵州省黄平县土地主题变化引发的生态扰动进行定量评价。结果表明:近10年来生态用地面积虽有所增加,但呈现破碎化趋势;对生态用地的农业占用比建设侵占更为严重。
负结构扰动栅格与生态用地动态损益明显的区域一致。在负结构扰动的格网中,生态破碎化对生境增加的影响大于生境增加。土地主题变化对供给、调节、支持和文化等生态系统服务功能有明显影响,FDI总量反映了它们之间的权衡关系。在石漠化地区和水土流失地区,FDI容易出现负值。综合分析SDI和FDI的变化特征表明,大多数网格具有同向的生态结构和功能扰动特征。这些发现提高了他们对生态干扰之间多重关系的理解,并为指导土地主题活动提供了有价值的信息。

Abstract: Land use change is a fundamental factor affecting ecosystem’s structures and functions. However, few studies have explored the ecological disturbance caused by land use change from a combined structural and functional perspective. In this study, the ecological structural disturbance index (SDI) and functional disturbance index (FDI) were introduced to quantitatively evaluate ecological disturbance caused by land use change in a typical karst area—Huangping County, Guizhou Province, China during 2009–2019. Results show that although the area of ecological land increased during past 10 yr, there had been a fragmentation trend of ecological land. Agricultural occupation was more severe than construction encroachment on ecological land. The grids with negative structural disturbance were consistent with areas of obvious dynamic loss and gain of ecological land. Ecological fragmentation had a greater impact than habitat gain in grids with negative structural disturbance. The ecosystem service functions of supply, adjustment, support, and culture were obviously affected by land use change, and the total FDI reflects the trade-off among them. Negative FDI values were easily observed in the rocky desertification area or water and soil loss area. The combination analysis of the SDI and FDI indicated the characteristic of co-directional ecologically structural and functional disturbance in the majority of grids. The findings improve our understanding of multiple relationships among ecological disturbances and provide valuable information for guiding land use activities.
