Urban land consolidation, which reforms land parcels to remove fragmentation and produce ideal blocks, is an effective means of urban renewal. Successful urban land consolidation benefits city officials as well as the general public, in improved city image, increased land value, and more effective land use. However, urban land consolidation can be ecologically detrimental to the environment, while land consolidation has focused solely on development for human benefit. To remove the negative effects of urban land consolidation on the ecological system, this paper establishes a set of criteria for evaluating ecological impacts of an urban land consolidation plan. The current study first identifies key ecological indicators using a special group decision-making process called "habitual domain analysis" and then records individual weighting of each indicator by an analytical hierarchy process, thus developing an urban ecological evaluation model with four levels and twenty-three indicators.

Miestų žemės sujungimas, kurio metu pertvarkomi žemės sklypai, pašalinamas susiskaldymas, pateikiami pavyzdiniai blokai, yra veiksmingos miestų atnaujinimo priemonės. Sėkmingas miestų žemės sujungimas naudingas miestų vadovams, taip pat plačiajai visuomenei, nes pagerina miesto įvaizdį, padidina žemės vertę ir veiksmingesnį žemės naudojimą. Tačiau miesto žemės sujungimas gali buti ekologiškai kenksmingas aplinkai, nes tai atliekama tik žmonių naudai. Siekiant pašalinti neigiamą miestų žemės sujungimo poveikį ekologinei sistemai, šiame straipsnyje nustatomi tam tikri kriterijai, kuriais vadovaujantis vertinamas ekologinis miestų žemės sujungimo poveikis. Dabartinis tyrimas pirmiausia nustato pagrindinius ekologinius rodiklius, taikant specialų grupės sprendimų priėmimo metodą, vadinamą įprastos aplinkos analize. Tada, atsižvelgiant į analitinį hierarchijos procesą, pagal svarbą nurodomi atskiri rodikliai ir sudaromas keturių lygių ir dvidešimt trijų rodiklių miesto ekologinis įvertinimas.
