| 摘 要： | 为了对退耕还林工程的生态效益进行全面、系统、科学地定量化评估,首先综合中国森林区划,退耕还林区、森林生态站和DEM数据,并与GIS空间分析相耦合构建了中国退耕还林生态效益监测网络。该网络包含130个退耕还林生态效益监测区,共布设157个监测站,其中已经建设79个,计划建设78个;其次利用全国退耕还林县级单位数据对网络规划布局结果进行了精度评价,总精度达到96.2%;最后指出了不同退耕还林区生态效益监测的主要侧重点。该网络可以实现对中国退耕还林工程区内生态要素的连续观测与清查,为退耕还林工程的生态效益评估提供数据支撑,并为辅助决策分析提供依据。

| Abstract: | In order to quantitatively assess ecological benefits of China grain for green project, an ecological benefits monitoring network was constructed by integrated data of China forestry zone, grain for green zone, forest ecology station and DEM data interconnecting with spatial analysis of GIS firstly. The network included 130 grain for green ecological monitoring zones and 157 ecological stations, in which 79 were established and the remaining 78 stations were in planning. Secondly, accuracy assessment of this network was done based on county-level data of grain for green project, and the total accuracy was 96.2%. Furthermore, the main focuses of different ecological benefits monitoring of grain for green project were pointed out. The network can implement forest ecological inventory in the area of China grain for green project, and provide data and decision support for the ecological benefit assess of the project. |
