Abstract: In order to solve the problem of quantification of comprehensive assessment of environmental quality impact in land consolidation planning, the author used comprehensive quantitative assessment method on environmental quality impact in land consolidation planning. By taking the change in the land use structure caused by the planning as an entry point and the impact on environmental systems structure-function-value in the implementation of the planning as the object of study, environmental quality impact assessment index system was established. Meanwhile, quantitative assessment model of environment quality comprehensive impact index method was put forward, which was used to assess environmental quality impact of the planning in Shangqiu quantitatively. The assessment index was easy to be valued quantitatively and assessment model of comprehensive impact index method was easy to apply. The impact value of the planning on environmental quality index was +11.76, which showed that the impact of the planning on environmental system structure-function-value environmental system was advantageous overall. The results indicated that: environmental quality impact assessment index system, established by the impact on environmental system structure-function-value in the implementation of the planning, had strong pertinence and the index were easy to be valued quantitatively. By environment quality impact comprehensive assessment model method, the assessment was simplified greatly. This method was practical and had the value of application.
