This paper tries to establish an index system to evaluate agricultural and rural infrastructures in NingXia from the following four aspects:infrastructures of agricultural production，infrastructures of rural life，infrastructures of social development in rural areas and forestry and rural ecological facilities.On that basis,this paper selects the data obtained during the period from 1999 to 2008 to make quantitative evaluation on the current agricultural and rural infrastructures of NingXia.The results show that the agricultural and rural infrastructure of northern NingXia is 74% of the national average and that of southern Ningxia is 62% of the national average and 83.8% of Northern Ningxia’s average respectively.Using gray systematic prediction model,this paper finally predicts the development of agricultural and rural infrastructures and puts forward corresponding countermeasures on how to quicken the construction of agricultural and rural infrastructures in Ningxia.
