Abstract:

At present,the sampling method of forest resources survey in China has some disadvantages,such as poor adaptability and strong spatial correlation.With the improvement of investigation accuracy and the change of social and economic conditions,the theory and method of spatial balance sampling (SBS) came into being.In this paper,the performance indexes of sampling accuracy,sampling efficiency and spatial correlation of 3 different sampling schemes of spatial balance sampling and traditional sampling are compared and analyzed by taking Haikou as the research case.The results show that:1) in the simulated sampling of various areas of Haikou,the sampling accuracy from high to low is the spatial balance sampling > system sampling > simple random sampling;2) in the simulated sampling performance evaluation,the spatial correlation,sampling accuracy and sampling efficiency of spatial balance sampling are better than simple random sampling and system sampling.This study aims to explore more economical and applicable methods for forest resource survey,in order to provide scientific basis for forestry development.
