【摘要】 松花江干流沿岸防护林存在着防护林树种及林分结构单一、防护林质量及景观多样性较差、防护林模式配置不够科学合理等问题。为此,本文调查选取适宜松花江沿岸种植的乔木、灌木及草本植物,搭配20种人工防护林配置方案。研究确定综合评价人工防护林功能效益的3个基本准则,即防护功能、景观功能和经济效益,并依据3个基本准则选取7个评价指标,建立人工防护林综合评价结构模型。运用层次分析法和熵权法对20种人工防护林配置方案进行优选。研究结果表明:多种乔木、灌木和草本植物搭配种植的方式能最大发挥防护林的综合功能效益,依据综合评价值确定第(20)、 (8)、 (17)、 (18)、 (11)、 (16)、 (14)种方案为最优配置方式。为松花江干流沿岸人工防护林的建设提供科学支撑。更多还原

【Abstract】 There are some problems in the shelter forest along the main stream of Songhua River, such as single tree species, single stand structure, poor quality, poor landscape diversity of shelter forest and unscientific allocation of shelter forest model. Based on this, after investigation, this paper selects trees, shrubs and herbs suitable for planting along the Songhua River, and matches 20 kinds of artificial shelter forest allocation schemes. Three basic criteria(protection function, landscape function and economic benefit) are determined. Seven evaluation indexes are selected according to the three basic criteria, and a comprehensive evaluation structure model of artificial shelter forest is established. The allocation schemes of 20 kinds of artificial shelter forest are optimized by analytic hierarchy process and entropy weight method. The results show that the combined planting of trees, shrubs and herbs can maximize the comprehensive functional benefits of shelter forest. According to the comprehensive evaluation values, the schemes of (20), (8), (17), (18), (11), (16) and (14) are determined as the best plans. This paper provides scientific support for the construction of artificial shelter forest along the main stream of Songhua River.更多还原
