Study on Big Data Based Land Use Performance in Yunnan Province

Based on large data, this paper takes sixteen prefectures in Yunnan Province as the object of study to establish the evaluation system with land use performance as the destination layer and land input level, land use degree, land use efficiency and sustainability of land use as the criterion layer for elevating the land use performance by collecting land use and social & economic development data in the study area from 2005 to 2014 by the method of TOPSIS. And it gets conclusions as follows: (1) The overall level of land use performance in Yunnan Province is not high. Most areas experienced a low to intermediate transition in land use performance, and thus the level of land use is low; (2) From 2005 to 2014, the land use performance in Kunming, Qujing, Baoshan and Honghe was on the rise, while that in the other twelve regions, including Lijiang and Dali, was fluctuating upward; (3) There is a big gap in land use performance within Yunnan Province.
