To　quickly　evaluate　the　material　properties　of　ancient　wooden　structure　members　on　site,　the　larch　species　of　northeastern　China　was　used　as　the　research　object,　and　the　nondestructive　testing　method　of　the　stress　wave　and　the　micro-drill　resistance　meter　were　used　to　measure　it.　The　variation　laws　of　the　larch　wood＇s　cross　and　longitudinal　property　indexes　were　determined.　According　to　the　variation　law　of　material　property　indexes,　the　detection　divisions　under　the　nondestructive　testing　technology　of　stress　wave　and　micro-drill　resistance　instruments　were　divided,　which　provides　a　basis　for　improving　the　accuracy　of　on-site　nondestructive　testing.　From　the　comparison　of　shade　and　light　side　data,　it　was　found　that　there　was　little　difference　in　material　properties　indexes.　According　to　the　change　trend　of　larch　wood　with　density,　the　pith,　juvenile　wood,　mature　wood,　and　overmature　wood　were　divided,　which　provided　a　reference　value　for　the　study　of　wood　growth　laws.
