摘要:

传统抽样方法因存在适应性弱、空间相关性高等缺陷,越发不适用我国的森林资源调查。随着调查精度要求提高和社会经济条件变化,空间平衡抽样(SBS)的理论与方法应运而生。以海口市为研究案例,对空间平衡抽样与传统抽样方法进行抽样精度、抽样效率和空间相关性等性能指标的比较分析。研究表明:1)在海口市各地类面积模拟抽样中,抽样精度从高到低依次为空间平衡抽样>系统抽样>简单随机抽样;2)在模拟抽样性能评价中,空间平衡抽样的空间相关性、抽样精度和抽样效率均优于简单随机抽样、系统抽样。 通过研究,以期为森林资源调查探索出更为经济适用的方法途径,为提高森林资源调查效率提供科学依据。

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.
