摘　　要：全域土地综合整治是实施乡村振兴战略的重要抓手,也是提升农村土地整治效果的有效途径。为探索服务全域整治目标的土地利用优化配置方法,借助非优势排序遗传算法在进化模拟、全局搜索等多目标决策优化中的优势,从转型条件、面积约束、效益测算等方面构建约束多目标土地利用优化配置模型(Constrained Multi-objective Optimization of Land-use Allocation,CoMOLA),同时借鉴首位度理论改进模型并选取典型研究区进行案例分析。通过设置经济优先、生态优先及生产优先3种不同发展情景优化土地利用土地管理配置,利用中间结果识别未来发展可能的冲突,为规划制定提供依据。研究结果表明:1)经济优先情景下,研究区2030年经济效益较基期年(2018年)增长了12.33%,生态效益和生产产量分别减少了11.41%和3.73%;生态优先和生产优先情景下,生态效益和生产产量分别提高了51.68%、11.63%;2)土地利用数量结构与空间结构在3种情景中均存在一定的极化趋势,绝对冲突地块面积分别为1.98%、3.12%和1.71%。需结合发展目标等多重因素,参考冲突识别结果,因地制宜制定发展方案。综合而言,运用改进约束多目标土地利用优化配置模型进行研究,能同时满足土地利用的时空特征,得到较为客观的土地利用土地管理优化方案,且其中间结果可作为地类发展冲突识别依据,可为多目标优化问题提供新的方法借鉴。The comprehensive land consolidation is an important channel to enhance the efficiency of rural land use for the implementing the strategy of rural revitalization.Therefore,the type optimization of land use and land management can be focused,in order to guide the specific methods of land plan.In this study,a Constrained Multi-objective Optimization of Land-use Allocation(CoMOLA)model was constructed from the aspects of transformation conditions,area constraints,benefit calculation,with the advantage of non-dominated sorting genetic algorithm II in evolution simulation,global search and other multi-objective decision.Law of the primate city was introduced to strengthen the model,while the typical research areas were selected for case analysis.The improved CoMOLA model and the different development scenarios were proposed to simulate the land use and management allocation,and the intermediate results can also be used to identify possible land conflicts in future.The results showed that:1)Under the economic priority scenario,the economic benefits of study area increased by 12.33%over the base period,but it would come at the cost of certain ecological benefits and production output,which reduced by 11.41%and 3.73%,respectively.Under the ecological priority scenario and production priority scenario,the ecological benefit and production output increased by 51.68%and 11.63%respectively.The economic benefits decreased by 8.34%and 10.18%under these two scenarios,respectively.Each benefit can be improved in the given scenario.2)The quantity and spatial structure of land use showed a certain polarization trend in all three scenarios,and the absolute conflict plot area was 1.98%,3.12%and 1.71%,respectively.In practical application,it is necessary to combine multiple factors,such as development goal,and conflict identification,further to make development plans according to local conditions.The improved CoMOLA model can be suitable to optimize land use allocation,and meet the spatiotemporal characteristics of land use.The inte
