选取对农田防护林体系有重要影响的树种适应性、树种防护效果和社会经济状况3大类13个指标,利用层次分析法,对所选10个树种(或无性系)进行优选评价。结果表明,在影响优选评价因子中,树种的保存率贡献率最大,说明选择适生树种是营造农田防护林成功的前提;防护效果评价因子,尤其是树种的防风效果,是农田防护林能否得到充分发挥综合防护效益的关键,对优选分析评价具有重要影响;同时考虑农村社会经济方面因素,才能得出客观、准确的优选评价结果。10个树种(或无性系)优选评价排序为:苏柳J172>苏柳J369>苏柳J194>青刚柳>准噶尔柳>二白杨>新疆杨>河北杨>三倍体毛白杨BT85>三倍体毛白杨B1008。
Thirteen indices of three kinds of tree species adaptability, protective effect of tree species and socioeconomic status, which have an important impact on farmland shelterbelt system, were selected to evaluate the selected 10 tree species (or clones) by using AHP. The results showed that among the influencing factors, the contribution rate of species conservation was the highest, indicating that the selection of suitable tree species was the prerequisite for the successful establishment of farmland shelterbelts. The protective effect evaluation factors, especially the windbreak effect of tree species, were sufficient for farmland shelterbelts The key to comprehensive defense effectiveness is to have an important influence on the optimal analysis and evaluation. Only by considering the social and economic aspects in rural areas can objective and accurate evaluation results be obtained objectively and accurately. The evaluation of 10 tree species (or clones) is as follows: Suliu J172> Suliu J369> Suliu J194> Qinggangliu> Junggar Liu> Populus × Populus> Populus × Populus> Populus euphratica> Triploid Populus tomentosa BT85> Triploid Poplar B1008.
