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.

基于AHP的海湾植被景观空间格局优化方法

植被景观是海湾城市的重要组成部分,在海洋生态系统,城市生态安全以及居民的休闲娱乐中发挥着重要作用。以深圳湾海岸公园为研究对象,提出了基于层次分析法的海湾植被景观空间格局优化方法。通过随机图像获取,获得了公园内植物景观的30种空间格局。以视觉质量和生态效率为评价标准,选择了12个评价指标,建立了基于层次分析法的海湾植被景观空间格局评价体系,确定了各评价因子的权重并进行了检验。利用植被景观综合评价指标法确定植被景观综合评价得分。根据得分,将植被景观的质量等级分为I,II,III和IV级。结果表明,深圳湾海岸公园植被景观质量达不到I级,其中12级为II级,占40.0%,其中18级为III级,占60.0%,没有四级景观,说明深圳湾海岸公园植被景观质量良好,但没有优秀的植物景观。根据评估结果,从宏观角度提出海湾植被景观空间格局的优化策略,植被景观质量等级分为一级,二级,三级和四级。结果表明,深圳湾海岸公园植被景观质量达不到I级,其中12级为II级,占40.0%,其中18级为III级,占60.0%,没有四级景观,说明深圳湾海岸公园植被景观质量良好,但没有优秀的植物景观。根据评估结果,从宏观角度提出海湾植被景观空间格局的优化策略,植被景观质量等级分为一级,二级,三级和四级。结果表明,深圳湾海岸公园植被景观质量达不到I级,其中12级为II级,占40.0%,其中18级为III级,占60.0%,没有四级景观,说明深圳湾海岸公园植被景观质量良好,但没有优秀的植物景观。根据评估结果,从宏观角度提出海湾植被景观空间格局的优化策略,其中三级以下的占18%,占60.0%,没有四级的景观,说明深圳湾海岸公园的植被景观质量较好,但没有优良的植物景观。根据评估结果,从宏观角度提出海湾植被景观空间格局的优化策略,其中三级以下的占18%,占60.0%,没有四级的景观,说明深圳湾海岸公园的植被景观质量较好,但没有优良的植物景观。根据评估结果,从宏观角度提出海湾植被景观空间格局的优化策略,中观和微观。
