2000-2011年三江源区植被覆盖时空变化特征
, PP. 897-908
Keywords: 植被覆盖,时空变化,三江源区,影响因素,未来趋势
Abstract:
基于MODIS-NDVI数据,辅以线性趋势分析、Hurst指数及偏相关系数等方法,本文从三个尺度分析了近12年三江源区植被覆盖时空变化特征、未来趋势及其驱动因素。结果表明(1)近12年三江源区植被覆盖呈现增加趋势,增速为1.2%/10a,其中长江源区、黄河源区植被均呈增加趋势,而澜沧江源区植被呈下降趋势。(2)三江源区植被覆盖具有显著的区域差异,且NDVI频度呈现“双峰”结构。(3)近12年三江源区植被覆盖呈增加趋势和减少趋势的面积分别占64.06%和35.94%,且表现为源区北部增加、南部减少的空间格局。(4)三江源区植被变化的反向特征显著,植被变化由改善趋势转为退化趋势的区域主要分布在长江源区和黄河源区的北部,而由退化趋势转为改善趋势的区域主要分布在澜沧江源区。(5)三江源区植被对降水和潜在蒸散的响应存在时滞现象,而对气温的响应不存在时滞现象。(6)三江源区植被覆盖的增加主要归因于气候暖湿化以及生态保护工程的实施。
