| Abstract: | Based on 3S technology,the sample investigation method in statistics,characteristics of land resources survey,three kinds of model were established which were data sample,double sample and unequal probability sample.The case suggested that these three methods can improve the work efficiency of land resource and could conduct dynamic monitor to the national land resources. |
