For　the　problems　of　complex　structure　design　and　hard　parameters　selection　on　echo　state　network　(ESN)　frame,　this　paper　proposes　a　structure　design　method　of　dynamic　neurons　reservoir　(DNR)　with　the　small　world　structure　(SWESN).　Design　method　of　SWESN　is　introduced　in　detail.　Neurons　space　growth　algorithm　is　used　to　generate　network　with　small　world　topology　structure　on　2-D　plane.　Then　the　neurons　are　rearranged　by　Euclidean　distance　from　network＇s　nodes　to　the　fiducial　node,　and　the　physical　nodes　of　the　plane　region　and　their　internal　connections　are　mapped　to　the　connection　matrixes　of　ESN　internal　neurons.　This　design　method　makes　the　DNR　have　small　world　property.　The　simulation　experiments　show　that,　the　proposed　ESN　can　create　more　abundant　dynamic　behavior　than　conventional　ESN,　and　both　robustness　and　anti-interference　ability　of　SWESN　are　better　than　that　of　conventional　ESN.
