The Ecological Compensation of Land Consolidation and Its Evaluation in Hilly Area of Southwest China

Land consolidation is an important action to realize the reasonable disposition of land resource and enhance the land utilization efficiency in China. But as a regional reconstructive activity, there are inevitably directly or indirectly, positive or negative impacts on its regional ecological environment in land consolidation process. To minimize the negative impact of land consolidation, positive practices for ecological compensation was necessary. Taken a land consolidation project in Yujia and Qiaoting village in Wanzhou District of Chongqing as case, the ecological compensation measures and ecological effect was studied in this paper. The result show that compensation practices such as protecting the arable layer, building slope-terrace, taking stone as the raw material for channels, irrigation channel and drainage channel separately in channel design, adopting the mud-gravel road, and building culvert in the intersections of roads and channels can significantly reduce the negative ecological effect in the processes of land consolidation. So, the eco-design in land consolidation project can realize ecological compensation and also achieve the coordinated development of economy, ecology, and society. (C) 2011 Published by Elsevier Ltd.
