Abstract:A set of evaluation indexes was established with the help of the ecological system of ‘nature-society-economy’ to solve fuzziness and randomness problems in the land ecological evaluation of Anhui Province. The normal cloud model and entropy weight theory are introduced to present study. The entropy weight method was used to the calculate the evaluation weight of factors, and the normal cloud model was used to describe the grade of land ecological security in Anhui Province under 23 indexes. The results showed that: 1) from 2005 to 2010 and 2013, the grade of land ecological security in Anhui Province increased from general to good and excellent status. 2) The values of land ecological security obtained with the comprehensive evaluation method were 0.1848, 0.3424 and 0.4730 in 2005, 2010 and 2013, respectively. These results suggested that the land ecological security in Anhui Province was improved continuouslly during last ten years, which was consistent with the results obtained by the normal cloud model. 3) The analyses of evaluation indexes indicated that there were 7, 13 and 17 indexes at good and excellent levels, and 16, 10 and 6 indexes at a general level in 2005, 2010 and 2013, respectively. Overall, the status of land ecological security in Anhui Province tends to be good performance in recent ten years, which was attributed to the conservation culture promotion in the province.
