摘要
[目的]分析江堤防护林示范区规划及实践效果。[方法]通过遥感影像处理对松花江干流沿岸防护林现状进行综合分析;提出了防护林规划设计基本原则;探讨了包括走向、间距、结构、配置、种植密度在内的防护林规划设计要素;总结了涉及树木特性、防护功能、景观功能3个指标层的9个功能指标以及专家打分法、层次分析法、熵权法相结合的评价方法;合理筛选植被配置方案对示范区展开实践建设。[结果]对建设初期效果进行分析,发现固土能力增加约45%,消浪能力增加约26%,生物多样性和景观功能均大幅提高。[结论]该研究为松花江干流沿岸防护林建设提供了理论与实践支撑。
[Objective]To study the planning and practice effect of the demonstration area of river embankment protection forest.[Method]The present situation of protection forest along the main stream of Songhua River was analyzed by means of remote sensing image processing.The basic principles of shelterbelt planning and design were put forward.The design elements of protection forest,including direction,spacing,structure,configuration and planting density,were discussed.We summarized 9 functional indexes related to tree characteristics,protective function and landscape function,as well as the evaluation method combining expert scoring method,analytic hierarchy process (AHP) method and entropy weight method.We put forward rational vegetation allocation plan for demonstration areas to carry out practical construction.[Result]Through the analysis of the initial effect of construction,it was found that the effect of soil consolidation increased about 45%,the effect of wave elimination increased about 26%,and the biodiversity and landscape function were greatly improved.[Conclusion]This study provides theoretical and practical support for the construction of shelterbelt along the main stream of Songhua River.
