摘要
以兴国县废弃矿区为研究对象,依据生态系统生产总值(GEP)核算当地生态系统服务,细化参数设置以核算功能量,并采用价格指数修正价值,以期应用于市场交易。2019~2020年兴国县废弃矿区生态修复工程实施后生态系统生产总值提升近709.13万元,约为修复前GEP的22.36倍;修复前,河流水面GEP>乔木林地GEP>果园GEP;气候调节服务GEP>水源涵养服务GEP>洪水调蓄服务GEP,三者占比达82.35%。修复后,水田GEP>乔木林地GEP>旱地GEP;土壤保持服务GEP>水源涵养服务GEP>气候调节服务GEP,三者占比达82.78%。
The abandoned mining areas in Xingguo County were taken as the research object, and the local ecosystem services were calculated according to gross ecosystem product(GEP). The parameter settings were optimized by the price index correction method, so as to be applied to market transactions. From 2019 to 2020, the total ecological system production value increased by nearly 7091300 yuan, about 22.36 times of the GEP before restoration. Before restoration, the order was GEP of river surface > GEP of tree forest > GEP of orchard;and climate regulation service GEP > water conservation service GEP>flood storage service GEP, accounting for 82.35%. After restoration, the order was GEP of paddy field>GEP of tree forest>GEP of dry land, and soil conservation service GEP>water conservation service GEP>climate regulation service GEP,accounting for 82.78%.
