Evaluation of Multi-functionality of Land Use Based on Entropy-weight TOPSIS Method in Wuhan City
[Objective] The multi-functionality of land use and its obstacles in Wuhan City during 2005-2017 was evaluated in terms of economy
society and ecology in order to improve the efficiency of land use and promote the rational regional land use and achieve regional sustainable development.[Methods] According to the target layer
index layer and element layer framework
an evaluation index system was constructed
and the entropy weight TOPSIS method was used to determine the index weight and calculate the obstacle degree.[Results] ① During the study period
the comprehensive function of land use in Wuhan City showed an overall upward trend
the coordination of functions showed a Z-shaped decline
the dominance of functional changes showed a wavy decline
and land use became increasingly diversified. ② The economic
social and ecological functions had different growth levels. Among them
the economic and social functions experienced low-intermediate-good-quality development stages
and the overall growth was rapid; the ecological functions experienced low-intermediate-quality development. At this stage
although there were small fluctuations
the overall growth was substantial. ③ The degree of economic and social dysfunction declined
while dysfunction of ecological functions continued to rise.[Conclusion] Wuhan City should pay attention to the improvement of ecological functions
transform the economic development mode
promote industrial upgrading
implement cleaner production
reduce the pollution of the three wastes
and pay attention to the protection of water resources and realize the sustainable use of land.
