摘要
小浪底工程建设及其运行对其上下游河岸带生态系统服务价值的影响不容忽视。对小浪底工程影响区域河岸带进行研究,并采用当量因子法评估小浪底工程建设和运行期不同区域河岸带生态系统服务价值。结果显示:小浪底工程建设期河岸带农田和草地面积增大;运营前期工程对研究区生态系统服务价值产生了正向影响,其中聊城—滨州段河岸带受影响幅度最大;运营后期工程对研究区生态系统服务价值产生的正向影响被黄河沿线的土地开发活动削弱,其中工程运营对河口段生态系统服务价值产生的负面影响最大。
It is worth noting that the impacts of Xiaolangdi Project construction and operation on the ecological service value of its upstream and downstream riparian zones.Therefore,this paper divided the upstream and downstream riparian zones affected by the Xiaolangdi Project into different sections,and utilized the equivalent factor method to assess the changes of different sections’riparian ecosystem service values during the project’s construction and operation period.The results show that it appears a decreasing trend in the land use area of the riparian farmland and grassland ecosystem during the project’s construction period;the project has caused a positive impact on the ecosystem service value during the early operation period,and the greatest impacts are found in Liaocheng-Binzhou section;during the later operation period,the positive impacts are weakened,while the negative impacts are enhanced when human activities along the superposition are added,among which the estuary area is suffered the most.
