| 摘 要： | 综合考虑与油橄榄生活习性密切相关的气候、土壤、地形等因素,利用GIS分析方法对空间数据进行组织与计算,结合AHP方法确定各参评因子权重,并选择适当的隶属函数和模糊算子对四川省油橄榄生态适宜性进行模糊综合评判。结果表明:基于GIS的模糊综合评判方法所得出的评价结果与目前四川省油橄榄引种区的分布大体一致,较之传统的评价方法有着评价周期短、评价结果更加精细、更有利于小区域范围内生态适宜性的确定等优点。

| Abstract: | In this paper,the ecological suitability of olive in Sichuan Province was evaluated,based on GIS-fuzzy comprehensive evaluation method.A comprehensive consideration was taken on the climatic,soil,and topographic factors related to olive growth.The spatial data of the factors were organized and computed with GIS method;the weights of the factors were derived by using AHP method;and the proper membership function and fuzzy arithmetic operators were selected to conduct the comprehensive ecological suitability ... |
