The Fuzzy Assessment of Sustainable Agriculture Development Potential of the Soil and Water Resource in Inner Mongolia

Based on the grading of indicators using fuzzy mathematics,taking the irrigation rate of cultivated land as the evalution factor,sustainable agriculture soil and water development potential assessment model is established.The results showed that sustainable agricultural land and water resources potential index of 12 leagues and cities in Inner Mongolia is from 1.025 to 3.252,the greatest potential index for HulunBuir City is 3.17 times than that of the smallest Wuhai City.According to the watershed assessment,the potential fluctuates in the range of 2.060 to 3.182,and the biggest Songhua River and Nenjiang River is 1.55 times than that of the smallest the Yellow River vally.The assessment model is reliable and feasible,and can be used to guide practice.
