   最后論述層析分析法在高速公路生態(tài)環(huán)境評價(jià)中的優(yōu)缺點(diǎn)，以此為今后高速公路生態(tài)環(huán)境影響評價(jià)研究提供參考依據(jù)。
3. So a number of evaluations have to be made . but , sometimes results of these evaluations will not be consistent with one another and even counteract , so the all - round evaluation is essential . there are some traditional methods such as ahp , and only the simplex matrix method is offered in this paper
   但是，各單項(xiàng)評價(jià)只是從某一個(gè)方面反映了各路網(wǎng)方案的優(yōu)劣，有時(shí)，各單項(xiàng)評價(jià)指標(biāo)會(huì)出現(xiàn)不一致甚至互相抵消的情況，因此，必須對路網(wǎng)方案進(jìn)行綜合評價(jià)，其常規(guī)綜合評價(jià)方法有價(jià)值分析法、單純矩陣法、層析分析法及主成份分析法等，論文中只給出了單純矩陣法。
