阐述了全国森林资源宏观监测的抽样框架设计及群团抽样设计;研究提出了针对图斑区划判读和群团样地判读2种方案的抽样估计方法,包括系统抽样、整群抽样和两阶抽样,其中整群抽样更适合于图斑区划判读,而两阶抽样更适合于群团样地判读;9个省的抽样估计结果对比表明,不等群团的整群抽样估计方法对图斑区划判读和群团样地判读都是合适的。
The sampling frame design and cluster sampling design of national forest resources macro-monitoring in China were expounded at first.In view of two interpretation ways,that is,department interpretation and cluster interpretation,some sampling estimation methods were presented,such as systematic sampling,cluster sampling and two-stage sampling,of which cluster sampling was more suitable to department interpretation and two-stage sampling was more suitable to cluster interpretation.From the comparison of sampling estimation results for 9 provinces,it was concluded that cluster sampling for unequal cluster size was suitable to both department interpretation and cluster interpretation.
