In addition, attention has rarely been paid to the systematic analysis of optimized goals of landscape pattern and ecological effect in land consolidation planning. Based on GIS and landscape metrics, this paper made an evaluation of the ecological effect by a proposed indices system towards the optimized landscape pattern through a typical land consolidation project. The proposed evaluation indices were oriented to five goals including promoting bio-diversity, maintaining material and energy circulation, stabilizing landscape pattern, keeping the level of life environment quality, and increasing ecological service value. The result of the employed land consolidation project in the paper showed both positive and negative ecological effect. The positive effect was indicated by the increased largest patch area, contagion index, corridor width and connectivity, corridor buffers, vegetation cover and strengthened functional zone along with the decreased patch density. Meanwhile, negative effect was manifested by the increased landscape diversity, decreased fraction dimension and reduced ecological service value. The paper thus finally suggested that landscape design and ecological protection must be taken into account in land consolidation planning. %K land consolidation %K landscape pattern %K ecological effect
