| Abstract: | Based on the data of the Zhongmo county of the forestry management inventory,by means of simple random sampling.two ranks sampling and layer sampling,a study was conducted on the estimation of the country and town stand volume sum of Zhongmo county.By contreest,it was found that the layer sampling after the event was better than the other two.Its estimated resolution can reach 0.898 6 and has a relatively high estimated efficiency |
| Keywords: | forest management inventory simple random sampling two ranks sampling layer sampling after the event estimated efficiency |
