Abstract:: The evaluation of cultivated land quality is the important basis to improve the quality of farmland and production capacity, it is also the important premise of the basic farmland protection and scientific construction of high standard basic farmland works carried out. Based on the in-depth analysis of cultivated land quality evaluation, the basis of the theory and method, and the basis of the quality of material, soil, climate, landscape, infrastructure, and scale of farmland, etc., the evaluation index system was established. The cultivated land quality and its spatial distribution were evaluated on the land unit, township and county scales using composite index, fuzzy clustering and GIS . The results show that in nature categories the first kind of cultivated land was 12 832.17 hm², accounting for 8.89%; the second kind of cultivated land area was 111 269.06 hm², accounting for 77.05%; the third kind of cultivated land area was 20 301.55 hm², accounting for 14.06%. Overall quality of cultivated land was average, it was mainly the second category in the west and the third was mainly in the east. In comprehensive categories, the first kind of cultivated land area was 60 794.01 hm², accounting for 42.10%; the second category was 56 950.72 hm², accounting for 39.44%; the third type was 60 794.01 hm², accounting for 18.45%. Comprehensive classification of the first kind of arable land proportion compared with the natural quality of cultivated land area ratio increased by 33.21%, the cultivated land quality improvement potential is greater, farmland infrastructure construction to improve the production capacity of cultivated land was significant.
