| 中文摘要 | 基于环渤海地区1999—2009期间年尺度的NDVI序列数据和半变异函数分析方法，定量研究植被覆盖分布的空间格局特征及其时间变化特征，结论如下：1）辽宁省地形对植被分布的影响强于气候，植被分布整体的连续性最好；而在山东和京津冀区域，温度对植被覆盖空间格局的影响强于水分，且山东植被分布的斑块化最为显著；2）结构性因子对辽宁、京津冀、山东三个分区植被覆盖的影响作用占主导，但均呈减弱趋势；3）辽宁、京津冀、山东三个分区植被覆盖空间变异最小、空间连续性最大的方向分别为东北一西南(30°)、西北-东南(150°)和西北—东南(135°)，该方向的差异体现了影响因子类型及其作用的差异性。 |
| 英文摘要 | The spatial-temporal characteristics of vegetation cover in the Circum-Bohai Sea Region from 1999 to 2009 were studied based on annual NDVI data and semi-variogram. Main conclusions are as follows. 1) The vegetation cover of Liaoning exhibited the highest continuity, while the fragmentization of the vegetation cover in Shandong Province was outstanding; impacts of terrain on the spatial distribution of vegetation cover were stronger than those of climate factors in Liaoning Province, while in Shandong Province and the Beijing-Tianjin-Hebei region, impacts of temperature were stronger than those of moisture; 2) Structural factors are dominating factors that impact on spatial patterns of vegetation cover in Liaoning Province, Shandong Province and Beijing-Tianjin-Hebei region, however, their impacts showed a weakening trend; 3) Directions in which the spatial patterns of vegetation cover were most continuous in Liaoning province, Shandong province and Beijing-Tianjin-Hebei region were northeast-southwest (30°), northwest-southeast (150°) and northwest-southeast (135°)， respectively， indicating the variability of impact factors' distribution and their roles in influencing the spatial patterns of vegetation cover. |
