基于“3S”技术的土地资源高效动态监测方法研究

摘要

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.%以“3S”技术为基础,利用统计学中的抽样调查方法,根据土地资源调查特点,建立成数抽样、双重抽样、不等概率抽样3种模型.实证分析表明,这3种方法大大提高了土地资源调查工作效率,可以对全国的土地资源进行动态监测.
