摘要
以2005—2016年石漠化监测数据为基础,分2005—2011年和2011—2016年两个阶段,从石漠化土地面积、程度、土地利用类型、植被综合盖度、石漠化土地演变状况、石漠化敏感性与发生率等指标,论述长江经济带石漠化土地动态变化状况与主要特点,以期为长江经济带石漠化防治与生态修复提供技术支撑。研究结果表明:生态工程持续推进、石漠化地区人口压力下降、农村能源结构优化、城镇基础设施建设,以及自然气候条件平稳等是石漠化土地朝良性向好演变的主要原因。
This article bases on the rocky desertification monitoring data from 2005 to 2016,divided into two stages,2005—2011 and 2011—2016,from such indicators as rocky desertification land area,degree,land use type,vegetation comprehensive coverage,rocky desertification land evolution status,the sensitivity and incidence etc.of rocky desertification,the dynamic changes and main characteristics of rocky desertification land in the Yangtze River Economic Belt has been expounded in order to provide technical support for rocky desertification control and ecological restoration in the Yangtze River Economic Belt.The results show that the continued progress of ecological projects,the population pressure falling in the rocky desertification region,the optimized structure of rural energy,the construction of urban infrastructure and stable natural climate conditions and so on are the main reasons for the benign evolution of rocky desertification land.
