Research on comprehensive evaluation to land consolidation supported by GIS: a case study of Shaoshan city in Hunan province

摘要

The quantitative evaluation of economic feasibility and eco-environmental impact of land consolidation can't be achieved by the conventional evaluation methods which lack of a comprehensive consideration of regional diversity. With the help of spatial analysis and data management, which are the fundamental functions of GIS, this paper provides a new method to perform the quantitative evaluation of the implementation conditions, the expected economic returns and the eco-environmental impact of land consolidation, and to establish a new evaluation system for the interrelation among the three of them in Shashan city, Hunan province. The economic feasibility and eco-environmental impact of each evaluation unit are comprehensively considered. The results of the evaluation can provide information for the site-choosing, the investment estimate, the benefit evaluation and the project management of land consolidation. The results of the evaluation can also provide useful advices for the design and the implementation of land consolidation.
