KARST, the Chinese SKA concept, consists of some 30 individual FAST-type elements to be set up in a karst region of Guizhou Province. A crucial question is how to select 30 optimized sites from hundreds of candidates. Here we introduce a uniform weight method, which can pick out suitable sites on the basis of uniformity and completeness of the u-v coverage. In order to meet some special scientific goals, such as imaging extended sources, a modification of this method is also discussed. Although the method is specially designed for the KARST array, it could be useful for more general types of arrays.
