Application of AHP-TOPSIS to the Evaluation and Classification of Provincial Landscape Construction Level of China

The urban green system constitutes the urban ecological infrastructure and plays a vital role in the healthy development of urban. This study, using Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) models, taking provinces in China as unit, has made analysis and thus carried out a classification of the landscape construction level of provinces in china from a macroscopic view. The results show that the provincial landscape construction level is positively correlated with the economic development level. But due to the big difference of landscape construction level of each province, enough importance should be attached. The AHP-TOPSIS model has good discrimination in the evaluation on China’s provincial landscape construction level and it is also applicable to the evaluation and classification of urban landscape construction level among different cities.
