RESEARCH ON THE APPLICATION OF MCDA METHOD IN COMPREHENSIVE EVALUATION OF RURAL RENEWAL

Under the background of the "rural revitalization" strategy, the protection and renewal of villages and towns have attracted increasing attention, which has effectively promoted the process of new-type urbanization in China. Tourism development with capital intervention, as a means of village protection and renewal, not only injects vitality into villages and towns, but also brings certain influence, making the original system of villages and towns more complicated. Taking yancheng XinFeng Town village as the research object, with all my heart, with the introduction of integrated community development, tourism development, the goal of traditional features comprehensive evaluation system, in order to put forward more reasonable protection and update the project strategy, by synthesizing various subject demands, and similar to the sustainable development of traditional villages and towns to provide a reference and reference. In this study, the multi-criteria evaluation method (MCDA) was introduced into the design of village renewal and reconstruction. According to the idea of multi-objective comprehensive development and multi-agent co-existence, the evaluation method was applied in multi-stage. First of all, AHP is introduced in this paper, referring to international conventions, current national norms and index elements in previous studies, and combining with the particularity of Xinfeng Town of Yancheng, the preset index system of village and town renewal evaluation system is preliminarily constructed. Secondly, through the analysis of specific cases to deepen the understanding of multi-objective conflict and multi-subject appeals, in order to modify the preliminary evaluation system indicators. Thirdly, this evaluation system is used as the basis for elastic adjustment. PROMETHEE method is used to evaluate the decision-making problems faced by Xinfeng Town in each stage of renovation process, and according to the evaluation results, protection and renewal strategies are proposed for each index in the subsystem of community development, tourism development and traditional style. Finally, the evaluation index system model of village and town renewal is used to make an empirical study in combination with xinfeng 920 Block, Quanxin Village, Xinfeng Town, Yancheng City. On the basis of the comprehensive evaluation results, the analysis is carried out from different subject perspectives and different index elements, providing reference for the comprehensive evaluation of village and town protection and renewal projects. It is found that through the evaluation of the pre-event, in-process and post-event stages in the process of renewal of villages and towns, the current value and problems can be relatively systematically analyzed in the evaluation of the current situation, so as to continue or improve the value characteristics of villages and towns themselves. In scheme design, the advantages and disadvantages of different schemes can be compared according to the evaluation results and combined with each other to promote scheme optimization; In the post-implementation evaluation stage, the built effect can be evaluated to feedback the design and formulate relevant guidelines to achieve the protection and renewal of similar villages and towns. In this process, the introduction of assistive technology will make the quantitative measurement of indicators more accurate, so as to increase the reliability of evaluation results.
