The　research　on　the　relation　between　niche　construction　and　its　evolution　is　a　new　field　of　study　of　the　niche　theory.　Taking　hazardous　resistant　site　of　land　use　as　the　research　object,　this　study　makes　a　systematic　analysis　of　the　development　of　the　concept　of　niche,　the　mechanism　of　the　niche　construction　and　the　special　pattern　of　the　coordinated　evolution　of　hazardous　resistant　site　of　land　use　and　the　change　of　their　environments.　This　paper　proposes　the　evolutionary　inertia　measured　by　the　fitness　of　the　niche　of　hazardous　resistant　site　of　land　use　and　the　evolutionary　momentum　measured　by　the　deviation　between　the　real　niche　and　the　optimal　niche.　This　paper　also　sets　up　the　appropriate　mathematical　model　by　making　a　case　study　of　5　sites　in　one　city.　The　study　results　can　be　used　as　the　theoretical　basis　for　hazardous　resistant　suitability　of　land　use　to　evaluate　and　choose.
