Abstract:

Based on the landscape quality,growth quality and stability,the indicator system of the quality evaluation of the eco-landscape forest belt around the city was constructed.The weights of the factors and indicators were determined by the comprehensive weights based on the analytic hierarchy process and the entropy method to evaluate the quality of the shelterbelt.The study results are as follows:the comprehensive weighting based on analytic hierarchy process and the entropy method better balanced the objective information of the evaluation indicators and the subjective will of the evaluators.Landscape quality has the highest weight in the criteria layer.Seasonal aspect diversity,tree mixed status and shrub layer coverage are the key indicators reflecting the comprehensive quality of the shelterbelt.Growth quality and stability of the shelterbelt is relatively high,while landscape quality is low,so the quality of the shelterbelt still has a great room for improvement.The mixed degree of tree species is not good,the seasonal variation is not obvious,and the coverage of understory shrubs is not high,which is the main factor affecting the quality of the forest belt around a city.Focusing on the quality improvement of shelterbelt landscape,improving the stand of coniferous forest and evergreen broad-leaved forest,increasing the mixed degree of tree species,the seasonal variation and structural integrity of the stand,and adjusting the stand density reasonably,promoting the growth of understory shrubs and improving the biodiversity of forest belts in the process of protection are the main ways to improve the quality of the forest belt around a city

Key words: the forest belt around a city, entropymethod, analytic hierarchy process(AHP), comprehensive weighting method, quality evaluation
