| 摘 要： | 为衡量经济发达地区的生态资产价值,文章以人-地关系日趋紧张的江苏沿海地区为研究对象,基于卫星遥感影像和统计资料,获取典型年份土地利用与覆盖变化信息,结合生态系统服务价值当量因子法开展生态系统生产总值的核算和评价研究。研究结果表明:研究期内,江苏沿海地区的湿地和光滩面积呈减少趋势,建设用地、林地和养殖水域面积呈增加趋势;江苏沿海地区的生态系统生产总值均在110亿元以上,从存量来看贡献排在前两位的生态系统类型依次是农田和养殖水域,从流量来看贡献排在前两位的生态系统服务价值依次是废弃物吸纳和水源涵养,体现巨大的生态系统服务价值潜力。研究结果可为有关部门开展生态保护工作提供参考。

| Abstract: | In order to measure the value of ecological assets in economically developed areas,the paper took the coastal area of Jiangsu Province as the research object,obtained land use and cover change information in typical years based on satellite remote sensing images and statistical data,combined with ecosystem service value equivalent factor method.Calculation and evaluation of gross ecosystem product in the study area was carried out.The results showed that: during the investigation period,the area of wetland and bare beach in the coastal area of Jiangsu Province decreased gradually,and the construction land,forest land and aquaculture water area showed an increasing trend;the total gross ecosystem product of the coastal area of Jiangsu Province was more than 11 billion yuan,and the contribution of farmland ecosystem and aquaculture water ecosystem ranked the top 2 in terms of stocks rate,and the contribution of value of water conservation and the value of waste absorption ranked the top 2 in terms of flows rate,which reflected the huge potential of ecosystem service value in the region.The research results could provide reference for the relevant departments to carry out ecological protection work. |
