Abstract:
With the increasing of urbanization and the rapid economic development, the rural water resources protection has more and more problems. In this paper, an evaluation index system of rural water resources protection in Hunan province was developed using the grey correlation degree approach based on the optimal combination weight method, and this evaluation index system was applied to investigate the status of rural water resources protection in Hunan province in 2010. .The results showed that four indexes are the most relevant factors with rural water resources protection, including the vegetation coverage, the completeness and implementation of policies, the effective irrigation rate, and the average fertilizer application rate per hectare. Finally, the improved model of GM(1.1) was used to predicate the variation trends of ten main indexes from 2011 to 2016. Model test parameters reached the qualified levels. The predicted results can offer decision-making references for rural water resources protection.
