Study on Remote Sensing Estimation of Cotton Planting Area Based on Additional Subpopulation Sampling under Overall Spatial Sampling Design
摘要
Abstract
In the method of crop acreage estimation based on the combination of remote sensing and sampling,the estimation of the parameters of the subpopulation requires a new sampling system design and the large workload of a field survey,the crop planting area remote sensing measurement method based on additional subpopulation sampling under overall spatial sampling design was lack.This paper took the Shawan county,Manasi county and Hutubi county as the research areas,and put forward a cotton planting area remote sensing measurement method based on additional subpopulation sampling under overall spatial sampling design with remote sensing and probability proportionate to size sampling.Finally,the data of cotton growing area released by Bureau of Statistics of Xinjiang Construction Corps were compared with the results of the sampling estimation.The results showed that the coefficient of variation of estimator of subpopulation in the study area was 0.023 3 after the additional sampling design,far below 0.05;but before the additional sampling design,which was 0.122 3,illustrating that the representative of the sample under the method had been enhanced greatly.Compared with the data released by Bureau of Statistics of Xinjiang Construction Corps,cotton planting area extraction accuracy of subpopulation in the study area reached 94.2%.This method could extract the cotton growing area of subpopulation effectively;at the same time,it could avoid the waste of human,material and financial resources and other resources needed to reestablish the sub population in the study area sampling system.关键词
