摘要：利用三峡库区黑沟小流域退耕还林工程实施前后监测资料,并基于AnnAGNPS模型获取该流域径流、土壤侵蚀和养分流失等数据,客观计量流域10种情景(A～J)生态服务物质量,进而估算各情景生态服务价值量。结果表明:退耕还林实施的10种情景中,流域生态服务物质量均发生了变化。情景B之径流、泥沙、总氮、总磷和有机碳的年输出量最高,分别为455mm、56.8t.hm-2、132kg.hm-2、33kg.hm-2和678kg.hm-2,而情景J中上述指标最低,分别为303mm、4.8t.hm-2、75kg.hm-2、18kg.hm-2和383kg.hm-2,分别下降了33.4%、91.5%、43.1%、45.4%和43.5%;退耕还林工程不同阶段流域生态服务价值也发生了变化,情景B最低,为225万元,情景J最高,为291万元,增加了29.3%。利用实地监测和模型输出的方法进行流域生态服务价值量的计量较为客观,避免了一些生态效益计算上的盲目性,但该方法所需数据量庞大,过程繁杂,限制了其推广应用。
Based on the long-term site-specific observed data and AnnAGNPS model,this paper valuated the changes of ecosystem services in Heigou forested watershed in Three Gorges Reservoir area under the scenarios A-J of Converting Cropland to Forestland Project（CCFP）.It was found that the quality of the ecosystem services in the watershed varied with the scenarios.The annual outputs of runoff,sediment yield,total nitrogen,total phosphorus,and total organic carbon from Heigou watershed were the highest under scenario B,being 455 mm,56.8 t·hm-2,132 kg·hm-2,33 kg·hm-2,and 678 kg·hm-2,and the lowest under scenario J,being 303 mm,4.8 t·hm-2,75 kg·hm-2,18 kg·hm-2,and 383 kg·hm-2,with a reduce of 33.4%,91.5%,43.1%,45.4%,and 43.5%,respectively.The ecosystem services value in the watershed also varied with CCTP implementation stages,which was the lowest（225×104 yuan）under scenario B and the highest（291×104 yuan）under scenario J,and increased by 29.3% under scenario J at the stages before and after CCTP.The method of using observed data and AnnAGNPS model was relatively objective,which reduced the uncertainty of the quantity of ecosystem services.However,this method not only needs a large amount of data,but also has a very complicated process,which might limit its application in assessing the ecosystem services value in some other places.
