摘　　要：对村镇进行"三生空间"土地适宜性评价,是实现资源的集约高效利用,缓解城乡用地的供需矛盾,协调引导生产、生活和生态空间共生发展的强大纽带。然而"三生空间"视角下土地适宜性评价存在方法单一、评价指标选取不足的问题,物元模型能更全面地掌握待评价对象在单因子指标上的具体表现,极大提升"三生空间"土地利用适宜性评价的精确性。本研究基于物元模型对重庆市永川区村镇土地利用适宜性进行评价,发现62.5%村镇建设用地处于适宜状态(包括最适宜、高适宜),而吉安镇、何埂镇、仙龙镇和朱沱镇土地利用不合理的现象相对突出。在未来规划和建设中,对于土地利用适宜度低的村镇应引起重视,科学制定规划、合理利用村镇土地。Land suitability evaluation of ecological-production-living spaces in villages and towns is a powerful link to achieve intensive and efficient use of resources,alleviate the contradiction between supply and demand of urban and rural land,and coordinate and guide the symbiotic development of production,living,and ecological spaces.However,from the perspective of ecological-production-living spaces,there are problems with the single method of land suitability and insu fficient selection of evaluation indicators.The matter-element model can more comprehensively grasp the specific performance of the object to be evaluated on the single factor index,which greatly improves the accuracy of land-use suitability evaluation of ecological-production-living spaces.This research evaluated the suitability of land use in villages and towns of Yongchuan District,Chongqing City based on the matter-element model.It was found that 62.5%of the village and township construction land is in a suitable state(including the most suitable and highly suitable).The irrational land use in Ji'an Town,Hejing Town,Xianlong Town,and Zhutuo Town is relatively prominent.In the future planning and construction,attention must be paid to the villages and towns with low land use suitability,and scientific planning and rational use of village land must be made.
