笔者主要对山西省疏林地主要树种油松、刺槐、落叶松和侧柏进行生态功能评价. 首先采用专家咨询打分方法对影响生态功能的生态因子进行选取和划分,然后运用层次分析法分析生态因子的权重,并根据 K =1/∑Wi Xi 求出疏林地主要树种的平均生态功能指数,最后对其树种的生态功能进行评价. 结果得出,油松、落叶松、侧柏和刺槐的平均生态功能指数分别为0.628 5,0.583 7,0.438 5,0.436 9.表明油松和落叶松的生态功能相对较好,而侧柏和刺槐的生态功能相对较低.

This paper mainly evaluated the ecological function of the main tree species in open forest land in Shanxi prov-ince,such as Pinus tabulaeformis,Robinia pseudoacacia,Larix gmelinii and Platycladus orientalis.First, the ecological fac-tors which influenced the ecological functions were selected and divided through expert scoring method.Then using AHP the weight of ecological factors was analyzed and calculated the average index of ecological function of main tree species in open forest land according to the K =1/∑Wi Xi .Finally, the ecological function of the tree species was evaluated.The results were as follows, the average index of ecological function of Pinus tabulaeformis, Larix gmelinii, Platycladus oriental-is and Robinia pseudoacacia were respectively 0.628 5,0.583 7,0.438 5,0.436 9, which showed that the ecological func-tion of Pinus tabulaeformis and Larix gmelinii were relatively good and the ecological function of Platycladus orientalis and Robinia pseudoacacia were relatively low.
