摘　　要：以群落大小、连续性、色泽艳度、纯度、生境、分布频度和地理位置为评价指标,应用层次分析法建立了城市苔藓景观利用价值的评价模型.根据权重大小,指标重要性排序为:群落纯度(0.261)、色泽艳度(0.184)、生境(0.176)、大小(0.130)、分布频度(0. 111)、连续性(0. 092)以及位置(0.050).根据建立的模型,评估了上海市区具有代表性的40个苔藓群落的景观价值.结果表明:40个苔藓群落的景观价值可分成4级,I级、II级、III级和IV级分别占参评总样本数的32. 5%,35. 0%,15. 0%和17. 5%.景观价值高的群落的苔藓面积大,主要由苔藓组成,生长周期长,四季保持苔藓景观的连续性,多为土生,便于改建.并对城市苔藓景观的开发利用策略提出了建议.A model to evaluate the bryophyte landscapes values was built based on mdicators,which are community area,growth period,degree of colourful and bright,community purity,frequency of distribution,and geographic location by using analytic hierarchy process.According to their weights,seven factors were ranked as community purity(0.261),degree of colourful and bright(0.184),habitat(0.176),community area(0.130),distribution frequency(0.111),growth period(0.092)and geographic location(0.050).The landscape values of forty bryophyte communities in Shanghai city were evaluated by using the model.According to their scores,the forty communities were divided into four grades,which are Grade I(32.5%),Grade II(35.0%),Grade III(15.0%)and Grade IV(17.5%).The bryophyte communities with high landscape values were characterized by their large area,high dominance,long growth period,soil substrate(with easily modification and simulation).The strategies to utilize these communities of high landscape values were also proposed.
