摘  要:以河北省东南部黄骅市为研究区,利用遥感、气象数据和外业调查数据,采用植被净第一生产力进行生态服务价值估算及损益分析。结果表明:1990~2011年黄骅市耕地、盐碱地和湿地面积明显减少,建设用地、盐田、其他土地、园地、草地和水域面积持续增加;2011年单位面积生态服务价值湿地最大,为15.63 CNY/m^2·a,建设用地最小,为2.83 CNY/m^2·a;生态系统服务总价值21年间持续减少,共减少了3.01亿元;生态服务价值构成中,各功能价值量仅水源涵养价值先增加后减少,其他功能价值持续减少;基于生态服务价值损益情况,划分了四个生态服务价值类型区:生态价值持续增加区、生态价值持续减少区、先增后减区和先减后增区。研究成果为合理划定土地利用分区及土地整治项目区提供参考,为区域生态保护提供指导。Based on RS and meteorological data and field survey Province as the case, NPP analysis method was used to calculate data, taking the city of Huanghua in the southeast of Hebei ecological services value, and then the article analysed the change trend on its profit and loss. The results showed that from 1990 to 2011, the areas of cultivated land, saline land and wetland decreased significantly. Construction land, salt pan, other land, corner, grass land and water increased continuously. And ecosystem services value has reduced the total of 3.01 × 10^8 CNY. In 2011 years, ecosystem service value of per unit wetlands is the largest, which is 15.63 CNY, and per unit construction land is the smallest, only 2.83 CNY. During the constituents of the ecological service value, only water conservation value increased from 1990-2000, and decreased from 2000-2011, and other functional value continued to reduce. According to the profit and loss of ecological service value, the future pattern of ecological service value had four trends presented as follows: the sustainably-increased zone, the sustainably-decreased zone, the rise-to-descend zone and the descend-to-rise zone. This study can provide references and guidances not only for dividing land use zoning and land reclamation project area, but also for ecological protection.
