摘  要:
利用多阶抽样与实地调查技术相结合的方法,对三峡库区的林地蓄积量进行估测,并分析这种方法的抽样精度。结果表明:基于多阶抽样的林地蓄积量监测方法所估测的活立木蓄积量,与三峡库区一、二类清查数据进行误差分析,总体精度分别达到99.52%、94.19%,估计精度为87.16%,这种估测方法具有较好的总体精度和稳定性。

摘  要:
We used the multi-stage sampling technology and the field survey to estimate the forest stock volume of the Three Gorges Reservoir area,and analyzed the sampling accuracy. We took the error analysis between the standing volume by multistage sampling and the total standing volume by the Investigation I and II with the overall accuracy of 94.19% and 94.19%,respectively,and the estimating accuracy was 87.16%.
