层次分析法在北京西山风景游憩林树种选择中的应用

针对北京西山地区的立地条件与旅游发展规划的要求,应用层次分析法建立了景观游憩林树种选择的评价体系。结果表明：栾树、山杏、山桃、元宝枫、黄栌、臭椿、白蜡等落叶树种因其观赏性高且立地适应性较强,综合性状表现较好。由于抗性表现突出且四季常青,侧柏、油松两种常绿针叶树种综合评价也较高。在北京西山风景游憩林的营建中,树种选择宜采取针阔混交的方式,以花色、叶色较好的高分树种（山杏、黄栌、元宝枫、栾树、白蜡等）为基调,搭配常绿针叶树种（侧柏、油松）,营建以季相美景为特色的风景游憩林。

The appliance of analytic hierarchy in tree species selection for scenic & recreational forest of Beijing Xishan Mountain

To facilitate tourism development and to consider the local environment and ecosystem of Beijing Xishan Moutain,a set of standards for tree species selection was established using AHP.The result showed that Koelreuteria paniculata,Armeniaca sibirica,Amygdalus davidiana,Acer mono,Cotinus coggygria etc.got high appraisal because of their good ornamental characteristics and high adaptability,Pinus tabulaeformis and Pinus tabulaeformis were also showed good capability.In the construction of scenic recreational forest of Beijing Xishan Moutain,the mixed（needle leaf and broad leaf）construction style was suggested in the paper.It is the best design to creat seasonal beauty using colored-leaf trees as a central theme and mix them with evergreen conifers in this area.
