许多环境变量连续地散布在一个区域上，目标参数原来是变量的空间总和。在这种情况下，基于设计的方法下的连续人口范式可以方便地考虑。该设计是通过根据基于区域的规则镶嵌的分层协议定位样本位点来进行的。这种分层设计在实地使用，因为它们允许对研究区域进行均匀的采样。在本文中，我们证明了空间总体估计的镶嵌分层设计是非常准确的，正态分布的大样本。版权所有（C）2010约翰威利父子有限公司
Many environmental variables are continuously scattered over a region and the target parameter turns out to be the spatial total of the variable. In this setting, the design-based approach under the continuous-population paradigm may be conveniently considered. This design is carried out by locating sample sites according to stratified protocols based on a regular tessellation of the region. Such stratified designs are used in the field since they allow for an even sampling coverage of the study area. In this paper we show that the spatial total estimators under tessellation stratified designs are very accurate and normally distributed for large samples. Copyright (C) 2010 John Wiley & Sons, Ltd.
