The　latitude　and　longitude　coordinates　are　converted　into　Gaussian　plane　coordinates　through　the　forward　calculation　of　the　Gauss-Kruger　projection,　and　then　the　location　is　selected　through　the　center　of　gravity　method,　and　then　the　location　result　is　converted　into　the　latitude　and　longitude　coordinates　through　the　reverse　calculation　of　the　Gauss-Kruger　projection.　This　method　was　then　applied　to　the　location　of　distribution　centers　among　the　four　cities　in　Zhejiang　Province,　and　reasonable　results　were　obtained.　©　Published　under　licence　by　IOP　Publishing　Ltd.
