| 摘 要： | 针对常规生态服务价值评估方法时间长、工作量大、成本高和当量精度低的问题,永定河生态系统服务价值时空动态分析突破了传统静态评估方法。将GIS技术与因子当量表法相结合,测算出针对永定河河流生态系统的因子当量表和单位面积生态服务价值表,通过线性优化模型计算不同情景下各类土地利用类型面积,以期为生态修复目标提供直接的定量化参考依据。测算永定河北京段总当量为124.91,每当量单位面积生态服务价值基准为2 001.54万元/km2。林地、草地、耕地、水面和其他土地利用类型单位面积生态服务价值依次为28 824.7、2 954.3、1 808.5、215 906.3和565.8万元/km2,其中水生态系统文化娱乐服务功能单位面积服务价值最大,为161 735.1万元/km2。据此,建立了只需遥感影像数据即可快速精准地动态计算区域生态系统服务价值的多元一次回归模型,与基于实地调查法的永定河历史评估结果进行比较,平均偏差为4.54%。利用线性规划方法计算出研究区域生态系统服务价值最大值为2 212亿元,最小值为513亿元;当永定河水面面积最大时,生态系统服务价值为2 212亿元,水面面积最小时生态系统服务价值为976亿元,大于未经优化配置时的432亿元。

| Abstract: | Dynamic evaluation of Yongding river ecosystem services make a certain improvement of traditional static evaluation in long period work, mass amount of work, high price, low precision, and so on. By correlating TM remote sensing and equivalent weight factor, it is with ecosystem services value unit area of Yongding River ecosystem that established multi regression model could calculate based on a mere remote sensing data directly and precisely. What is more, the model is used to calculate the land use area corresponding to different ecosystem services for the propose of Yongding river restoration quantificationally. |
