摘要
从焉耆垦区生态环境建设和防护林体系保护的实际需求出发,通过林地资源监测和实地调查,以树种的生态适应性、生态功能、综合效益和观赏价值作为防护林树种选择的主要评价准则,选取抗寒能力、抗旱能力、抗蛀干害虫能力、防风能力、经济效益等15个评价因子作为指标。利用层次分析法建立3级评价体系,运用多目标线性加权和法得出该区域64种主要防护林树种的树种适应性评价的总体得分值(Y),并根据该数值对防护林树种的适宜性进行等级划分。分析得到,Ⅰ级(Y≥4.0)适宜性优良的树种有泓森槐、胡杨、新疆杨等8种,Ⅱ级(3.6≤Y<4.0)适宜性较好的树种有刺槐、沙枣、山楂、美国黑核桃等19种,Ⅲ级(3.2≤Y<3.6)适宜性一般的树种有樟子松、大果榛子、臭椿、苹果等19种,Ⅳ级(2.8≤Y<3.2)适宜性较差的树种有梣叶槭、白榆、垂柳等13种,Ⅴ级(Y<2.8)适宜性极差的树种有箭杆杨、黑杨、竹柳等5种。
Based on the actual needs of ecological environment construction and protection of shelter forest system in Yanqi Agricultural Area,this study selected the ecological adaptability,ecological function,comprehensive benefit and ornamental value of tree species as the main evaluation criteria for the selection of shelter forest tree species through forest resource monitoring and field investigation,and selected 15 evaluation factors such as cold resistance,drought resistance,stem borer resistance,windproof ability and economic benefit as indicators.The analytic hierarchy process was used to establish a three-level evaluation system,and the multi-objective linear weighted sum method was used to obtain the overall score(Y)of tree species adaptability evaluation of 64 main shelter forest tree species in the region,and the suitability of shelter forest tree species was classified according to the values of the score.According to the analysis,the tree species with excellent suitability at levelⅠ(Y≥4.0)included 8 species,such as Robinia pseudoacacia‘Hongsen’,Populus euphratica,P.alba var.pyramidalis,etc.;the tree species with good suitability at levelⅡ(3.6≤Y<4.0)included 19 species,such as R.pseudoacacia,Elaeagnus angustifolia,Crataegus pinnatifida,Juglans nigra,etc.;the tree species with average suitability at levelⅢ(3.2≤Y<3.6)included 19 species,such as Pinus sylvestris var.mongolica,Corylus heterophylla×C.avellana,Ailanthus altissima,Malus pumila,etc.;the tree species with poor suitability at levelⅣ(2.8≤Y<3.2)included 13 species,such as of Acer negundo,Ulmus pumila,Salix babylonica,etc.;at level V(Y<2.8),the tree species with very poor suitability included 5 species,such as P.nigra var.thevestina,P.nigra,S.hybrid,etc.
