| 摘 要： | 根据石羊河流域1980年、1990年和2010年三期遥感影像数据,基于GIS技术方法,分析了石羊河流域各县市的土地利用方式变化情况.评估了流域主要生态系统生态服务价值量,分析了30 a来流域生态系统服务价值在时间和空间上的变化.结果表明:过去30 a来,石羊河流域的土地利用变化主要以耕地、草地、未利用土地的变化为主.石羊河流域生态系统服务的总价值呈减少趋势,生态服务价值在空间分布上表现为下游呈增加趋势、中上游表现为减少趋势.流域下游生态服务价值增加的主要原因是流域生态保护与恢复措施取得了显著成效.

| Abstract: | According to the data of remote sensing images of the Shiyang River basin from 1980 through 2010,the change of land use mode in all counties and districts of the basin was analyzed based on GIS technology.The value of the main ecosystem services was assessed,and the watershed ecosystem service value from 1980 through 2010 were analyzed temporally and spatially.The results show that during this period land use change in the basin mainly exhibits in the changes of cultivated land,grassland and unused land.Spatially,the total ecosystem service value is decreasing,with total ecological service value increasing in the downstream and decreasing in the midstream and upstream.The main reason for the increase of ecological service value in the lower reaches is that the ecological protection and restoration measures have achieved remarkable results.River basin of the value of ecosystem services is growing with the expansion of arable land with ecological value services that are not related to the use of land converted to cropland.Meanwhile,in recent years continued basin ecosystem conservation and management measures of recovery has become increasingly effective,increasing the area of forest and grass,watershed ecosystem restoration so that the value of ecosystem services has increased. |
