山东省济南市水资源与土地整治潜力关系研究OA

Based on land change survey and water resources statistics,on the basis of analyzing present con-dition of water resources and farmland utilization,land consolidation potential and limiting factors in Ji'nan city,an evaluation index system and coupling coordination model of"water resources—soil quality—eco-logical security"have been constructed,and adaptability of regional water resources distribution and land consolidation potential have been carried out.It is showed that the coupling and coordination degree of wa-ter resources and land consolidation potential in Ji'nan city covers 4～10 degrees,and spatial differentiation characteristics are significant.According to the coordination level,it can be divided into four types of zones,with high coordination zones accounting for 12.2%,medium coordination zones accounting for 65.8%,low coordination zones accounting for 17.8%,and imbalanced zones accounting for 4.2%.The study has verified the rigid constraint effect of water resource endowment on the scale,layout and long-term u-tilization of land consolidation.It can provide scientific support for the formulation of differentiated land consolidation strategies and coordinated optimization of water and soil resources in Ji'nan city.
