摘  要：
森林枯落物层和土壤层持水能力监测是评价森林水源涵养功能优劣与否的两个重要环节。为了更直观、简便、科学、合理地对滇中城市水源地不同林型水源涵养功能进行评价,以森林不同林型枯落物持水量、土壤层理化特性及土壤持水能力研究为基础,选取影响林地枯落物层和土壤层持水功能的17个代表性评价指标,建立滇中城市水源地不同林型水源涵养功能评价指标体系。运用欧式贴近度的概念及模糊物元模型,构建基于欧式贴近度的模糊物元模型,并以楚雄市九龙甸水源地4种不同林型(混交林、人工桉树林、灌木林、青冈栎林)为例进行实证研究,得到欧式贴近度大小顺序为:R混交林>R青冈栎林>R灌木林>R人工桉树林,表明混交林综合水源涵养功能最好,其次为青冈栎林和灌木林,人工桉树林最差。

摘  要：
Forest litter layer and soil layer water-holding capacity are two important links to monitor whether the function of forest water conservation is good or not.In order to evaluate the water conservation function for different types of forest in central Yunnan urban water sources intuitively,simply,scientifically and reasonably,and on the basis of the different types of forest litter layer water-holding capacity,the physical and chemical properties of soil layer,and the soil water-holding capacity,17representative evaluation indicators which impact the forest litter layer and soil layer water-holding capacity as the evaluative indices of water conservation function was collected for different types of forest in central Yunnan urban water sources.The water conservation function of different forest types in Jiulongdian,Chuxiong was evaluated by using the Euclid approach degree fuzzy matter element model.The size of the European approach degree is in the oder of Rmixed forest>Rcyclobalanopsisglauca forest>Rshrub>Rman-made eucalyptus forest.It concludes that comprehensive water conservation function of the mixed forest is the best,followed by the cyclobalanopsis glauca forest and the shrubs,and the planted eucalyptus forest is the worst.
