摘要:

【目的】对树种进行综合评价可以为自然条件复杂的海滨城市道路绿化和廊道生态系统构建提供科学参考。【方法】以连云港市为例,对道路绿化常见的55个树种进行科学监测、调查和分析,采用层次分析法,设置5个一级指标:生态性、景观性、适应性、经济性和负面性,在此基础上设置30个二级指标,对各指标进行量化打分,确定各评价指标的权重值和赋值,建立海滨城市道路绿化树种综合评价体系。应用该评价体系,明确树种使用过程中存在的优劣势,并以最终得分对树种进行逐级分类。【结果】生态性方面,遮阴降温权重值最高(0.513 7);景观性方面,叶色、叶量和花的权重值最高(0.181 8);适应性方面,抗风、抗病虫害和耐盐碱性的权重值最高(0.174 0);经济性方面,指标层苗木价格和养护强度权重值均为0.4;负面性方面,飞絮花粉权重值最高为0.6。准则层各权重值中,生态性、景观性和适应性均为0.3,占比90%;经济性、负面性权重仅为0.05。评价结果表明,树形高大、枝叶浓密、抗逆性强的树种具有更高的评价得分。【结论】缓解热岛效应、改善生态环境是当前海滨城市绿化的主要目标。在树种选择时,应加大乡土树种应用比例,并在今后的道路绿化上作为骨架树种重点推广使用,同时应统筹考虑养护管理的经济性和飘絮花粉等负面影响。

Abstract:

【Objective】Comprehensive assessment of tree species can provide scientific references for road greening and gallery ecosystem construction in coastal cities with complex natural conditions.【Method】Lianyungang City was chosen as the case study. Fifty-five commonly seen tree species were scientifically monitored, surveyed and analyzed. The analytic hierarchy process (AHP) was adopted, and five Level-Ⅰ indexes were designed, including the ecological indexes, landscape indexes, adaptability indexes, economic indexes and negative consequences. On this basis, 30 Level-Ⅱ indexes were put forward and quantitatively marked. The weights and assignments of each assessment index were identified. Subsequently, a comprehensive assessment system for road greening tree species in coastal cities was developed. The assessment system is used to clarify the strengths and weaknesses of tree species in practical situations. The tree species were graded according to final scores.【Result】In terms of ecological indexes, the weight of overshadow and cooling performance was the highest (0.513 7). In terms of landscape indexes, the weight of leaf color, leaf amount and flower were the highest (0.181 8). In terms of adaptability indexes, the weight of resistance against wind, plant diseases, insect diseases, and salt and alkali were the highest (0.174 0). In terms of economic indexes, the weights of the seedling price and maintenance intensity at the index layer were both 0.4. In terms of negative consequences, the weight of fluffy catkin and pollen was the highest (0.6). At the criterion layer, the weight of ecological indexes, landscape indexes and adaptability was 0.3, accounting for 90% of the total; the weight of economic indexes and negative consequence was only 0.05. The assessment results suggest tree species are tall and large, with dense branches and leaves, and which are resistant to adverse conditions, scored higher.【Conclusion】Improving the ecological environment is the main greening goal of coastal cities. In choosing tree species, the authorities should increase the percentage of local tree species and promote them as backbone tree species for future road greening. At the same time, the economic performance of maintenance and management, and the negative consequences of fluffy catkin and pollen should be taken into consideration.
