摘要

To understand the spatial difference of agricultural sustainability in Tibet,this paper establishes a comprehensive evaluation model of agricultural sustainability to calculate the score of agricultural sustainability of 7 areas in 2013 in Tibet. By using cluster analysis,this paper conducts the regional evaluation of Tibet’s agricultural sustainability. The results show that 7 cities’ regional difference of agricultural sustainability was obvious in 2013,the agricultural sustainability index value was 0. 4232- 0. 6937,and the value was in the order of Nyingchi > Lhasa > Shannan > Ali > Shigatse > Qamdo > Nagqu. According to the agricultural sustainable development level,Tibet can be divided into three regions: the first type is the area with the highest level of sustainable development of agriculture,including Nyingchi and Lhasa; the second type is the area with the average level of sustainable development of agriculture,including Shigatse and Shannan; the third type is the area with the low level of sustainable development of agriculture,including Qamdo,Ali and Nagqu.
