摘要:以山东省滨州市为研究对象，利用2000、2005、2010年和2015年4期遥感影像数据划分土地利用类型，基于3km×3km评价小区格网化重采样，核算生态系统服务价值和生态风险指数，分析二者动态变化特征及时、空关联性。结果表明：（1）2000-2015年滨州市生态系统服务价值总量由168.06×10⁸元持续增长到205.30×10⁸元，生态风险指数呈现缓慢降低趋势，总体下降5.86%，区域生态安全问题有所改善；（2）单位面积生态系统服务价值和生态风险指数具有较强的正向等级相关性，并存在一定的正向空间关联性；（3）生态系统服务价值变化相对于生态风险指数具有一定的滞后性，高等级生态风险区域的生态系统服务价值存在极大的减小变化的可能性。研究有助于为区域生态安全格局建设和环境保护政策的制定提供参考。



Abstract:This study in Binzhou city of Shandong Province classified land use types by using remote sensing image data for 2000, 2005, 2010 and 2015, with a grid re-sampling size of 3km×3km in the study area. The ecosystem service value and ecological risk index were calculated and evaluated, and their dynamic changes and spatiotemporal correlations were analysed. The results showed that, (1) from 2000 to 2015, the total value of ecosystem services in Binzhou City continued to increase from 168.06×10⁸ yuan to 205.30×10⁸ yuan, and the ecological risk index showed a slowly decreasing trend, with an overall decline of 5.86%. Therefore, regional ecological security had improved, (2) the ecosystem service value per unit area and the ecological risk index were strongly positively correlated although with some positive spatial correlation and (3) the change of ecosystem service value lagged behind the ecological risk index to a certain extent, and there was a strong possibility of reducing the change of ecosystem service value in high-level ecological risk areas. This study will help to provide a baseline reference for the construction of regional ecological security patterns and the formulation of environmental protection policies.
