以河北省丰宁县为例，建立了县级生态资产计量技术体系，提出了基于高空间分辨率遥感数据的生态资产评估指标体系研究结果表明，时空自适应植被指数融合模型，该方法能够模拟TM NDVI时间序列数据，满足县级生态资产评估中NPP高精度估算的需要，丰宁县2008年生态资产总量为414.44亿元，单位面积价值在1123 ~ 390029元/hm 2之间。森林生态系统、灌草生态系统3种自然植被生态系统的生态资产达349.05亿元，丰宁市生态资产占总生态资产的84.22%因此，丰宁县自然生态系统在生态资产中具有重要的地位，研究成果对促进丰宁县生态环境建设具有重要意义。县级生态资产核算体系。
The technology system for measurement of county-level ecological asset was established in Fengning County,Hebei Province,the indicator system for ecological capital evaluation was brought up based on the remote sensing data of high spatial resolution ratio(Landsat-5 TM data and SPOT-5 data).The study results show that the spatial and temporal adaptive vegetation index fusion model,which can simulate the TM NDVI time series data and meet the need of the NPP high-precision estimate in county-level ecological capital evaluation,and the root mean square error(RMSE) of simulation result reached 0.0702.The total ecological asset in 2008 in Fengning was 41.444 billion yuan,and the unit area value was between 1123 yuan/hm2 and 390029 yuan/hm2.The ecological assets of three natural vegetation ecosystems include forest ecosystem,bush and grass ecosystem reached 34.905 billion yuan,and the percentage of the total ecological asset in Fengning was 84.22%.So the natural ecosystems had an important role in ecological assets in Fengning County.The research results had significance to promote the establishment of the accounting system of the county-level ecological assets.
