Landscape Ecological Planning and Design of Land Consolidation in Karst Area:A Case of Land Consolidation Project in Libo, Guizhou

Abstract

Land consolidation is a process of re-organizing and re-optimizing of the land resources and land use,and it changes land use types,spatial structure,landscape pattern and ecological process.Therefore it is urgent and important to carry out researches on the landscape ecological protection by land consolidation especially in fragile karst areas.Landscape ecological planning and design can effectively promote the protection and recov-ery of ecosystems,and such works are involved in land consolidation which is an important trend of develop-ment.In the paper,The main points of landscape ecological planning and design in land consolidation are dis-cussed.At the same time,taking a land consolidation project in Libo County,Guizhou as an example,the land-scape planning and design of farmland patches,irrigation and drainage engineering,road engineering and biodi-versity projection engineering are conducted.The aim of this research is to provide scientific insights into land-scape ecological planning and design and the ecological environment impact assessment of land consolidation.
