Architecture　is　considered　as　a　visual　stimulus　which　can　affect　the　people　physically　and　psychologically.　Researchers　have　shown　that　human　have　a　preference　on　images　of　natural　related　building　and　have　a　restorative　effect　improving　cognition　and　affection　level.　In　this　paper,　an　original　study　has　been　thoroughly　carried　out　to　objectively　and　quantitatively　prove　the　ecological　designed　military　camp　is　better　than　traditional　one　based　on　attention　restoration　theory　by　means　of　eye　tracking　techniques.　33　participants　viewed　172　images　from　both　target　and　reference　groups.　We　accomplished　to　demonstrate　that　(1)　People　can　noticeably　perceive　the　difference　between　the　high　and　low　fascination　images　both　cognitively　and　affectively　from　subjective　evaluation　and　objective　eye　tracking　metrics　(2)　The　ecological　designed　camp　indicates　in　preference　to　the　traditional　camp.　But　its　indoor　design　is　inferior　to　traditional　camp　from　the　measurement　of　reaction　time　and　scan　path.　(3)　People　feel　relatively　easy　to　make　a　decision　or　judgments　on　images　with　obvious　affection　tendency.　In　brief,　there　are　differences　in　behavioral　and　eye　movement　characteristics　when　people　observe　and　evaluate　the　ecological　camp　and　traditional　camp.　Both　the　experimental　paradigm　and　the　eye　tracking　metrics　are　firstly　mentioned　and　utilized　in　environmental　psychology,　which　is　a　well　worthy　reference　and　can　be　introduced　to　other　corresponding　research.
