摘要：以中高空间分辨率的Landsat-5 TM和SPOT-5遥感数据为主要数据源,以河北省丰宁县为例,提出了县级生态资产价值遥感评估的指标体系,研究建立了县级区域生态资产遥感测量的技术体系。研究结果表明,利用STAVFM时空尺度转换模型,可模拟获得县级区域全年时间序列的TM尺度NDVI数据,模拟结果验证的均方根误差仅为0.0702,可满足县级区域生态资产价值评估中NPP高精度遥感估算的需要;2008年丰宁县总生态资产价值为414.44亿元,单位面积生态资产价值在1123元/hm2至390029元/hm2之间,其中,森林、灌丛和草地三者的生态资产价值达349.05亿元,占该县生态资产总价值的84.22%,可见自然生态系统在丰宁县生态资产中所占的重要地位。研究结果对推动县域生态资产核算体系的建立有指导意义。
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/hm^2 and 390029 yuan/hm^2.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.
