摘要

Vegetation landscape is an important part of the Bay City, which plays an important role in the marine ecosystem, urban ecological security and residents' leisure and entertainment. Taking Shenzhen Bay Coastal Park as the research object, the optimization method for spatial pattern of vegetation landscape in Bay based on AHP was proposed in the paper. Through random image acquisition, 30 spatial patterns of plant landscape in the park were obtained; visual quality and ecological efficiency were used as the evaluation criteria, and 12 evaluation indexes were selected to build the evaluation system of spatial pattern of vegetation landscape in Bay based on AHP, and the weight value of each evaluation factor was determined and tested. The comprehensive evaluation score of vegetation landscape was determined by the comprehensive evaluation index method of vegetation landscape. According to the score, the quality grade of vegetation landscape was divided into grade I, II, III and IV. The results show that the quality of vegetation landscape in Shenzhen Bay Coastal Park is not up to grade I, 12 of them are up to grade II, accounting for 40.0%, 18 of them are up to grade III, accounting for 60.0%, and there is no landscape of grade IV, which shows that the quality of vegetation landscape in Shenzhen Bay Coastal Park is good, but there is no excellent plant landscape. Based on the evaluation results, the optimization strategy of spatial pattern of vegetation landscape in bay is proposed from the macro, meso and micro.
