以TM图像及MODIS NDVI数据为主要数据源，通过建立生态系统服务价值评估体系、物质量评估模型及价值量评估模型，对河北省2000—2009年生态系统服务价值进行了计算。2000—2009年间，河北省生态系统总服务价值呈现出波动增长趋势；总体的空间分布规律呈现出北高南低、西高东低、山地丘陵区高于平原区的规律；生态系统服务价值的空间变化呈现出南北两端地区减少、中部地区增加，且增加部分面积大于减少部分面积的特点。

Quite a lot of researches on the estimation of ecosystem service value have been carried out all over the world. Most of these researches were static evaluations at some points in time. From these researches we can only know the ecosystem service value of some places at some time points, but the dynamic changes of ecosystem service value could not be detected, especially in a continuous time span. In this paper, the ecosystem services valuation system and methods were developed. 5 kinds of ecosystem services, i. e. , fixation of solar energy, accumulation of nutrients, gas regulation, soil conservation and water conservation, were taken into account. The continuous monthly MODIS NDVI data from 2000 to 2009 were used as the main dataset to calculate the ecosystem services value in Hebei Province. A 10-year period of ecosystem services value was calculated and dynamic changes were analyzed. It is shown that the ecosystem services value of Hebei presented a dynamic increasing trend during this 10-year period. The average values were much higher in northern and western parts as well as mountain areas than in southern and eastern parts as well as plain areas. The ecosystem service values in northern and southern parts increased during the 10-year period, and the areas where the ecosystem service value increased were larger than those where the value decreased.
