汉英语境1
英译术语:
sampling
汉语语境:
已有研究表明，利用遥感空间抽样方法来监测耕地变化是可行的，如何选择最佳空间抽样方案以提高效率、节省费用则是其需解决的核心问题。采用3种抽样方法（简单随机抽样、分层抽样、系统抽样）与2种抽样框（规则抽样框、不规则抽样框），设计了6种不同组合的遥感空间抽样方案进行试验；根据不同抽样框与平均每样本调查费用大小的关系，分析了不同耕地变化遥感空间抽样调查方案的精度与效率，并以北京市顺义区为例进行了试验验证，
英语语境:
Previous researches have proved the feasibility of monitoring cropland changes using spatial sampling methods.However, how to improve efficiency and reduce cost by designing an optimal spatial sampling scheme is a key issue. Six sampling schemes were designed by combining three sampling methods (simple random sampling, stratified sampling andsystematic sampling) with two sampling frames (regular frame and irregular frame) and their accuracy and efficiency weretested, based on the relationship between the average survey cost per sample and the practice factor of sampling frame. A case study in Shunyi District, Beijing, was carried out to test the validity of the optimal spatial sampling scheme.
