Based on the understanding of current land ecological environment in Anhui Province, we mainly analyze the relationship between land consolidation planning and ecological environment, and point out the problems concerning ecological environment, such as great soil erosion, serious soil pollution, frequent geological disasters in local areas, and forest vegetation destruction. We divide the key ecological function conservation areas into the following areas: River Source Area, River and Flood Regulation and Storage Area, Key Water Conservation Area, Wind-preventing and Sand-fixing Area, Soil and Water Conservation Area. Finally we put forth the ecological security strategy for promoting land consolidation and ecological environmental protection.
