南水北调中线工程:水源地和输水区生态安全体系构建--兼论其景观生态学意义

分析了目前河南的经济社会及生态现状与保障水生态的安全所面临的双重矛盾,以河南的气候、树种的区系特征和物种的多样性为基础,从森林生态学和景观生态学的角度较为系统的、宏观的研究南水北调的中线工程源头区和干渠沿线的生态建设和保护,设计了中线工程(河南段)黄河以南干渠两侧以防护和景观为主的4种树种配置模式,黄河以北3种模式,并对其合理配置进行了研究,试图构建具有中原地域特色和深厚文化底韵的森林生态安全体系。

The Economic Geographical Base and Landscape Ecological Meaning of the Ecosafety System Construction of the Central Line Project of the South to North Water Division

This article analyses the conflict between water safety and economic-social-ecological status in He'nan. From the point of the silvics and the landscape ecology and on the character of Henan's climate and the tree species section system and the species diversity, the research filters the basic 129species of arbor and shrub as the ecological landscape construction and protection. From the aspects of the bio-diversity and the belt character of the vegetation, the integration of the ecology function, the natural succession of the species, the esthetics peculiarity of the landscape-hallway, the consciousness of the human-being and culture solicitude, it designs the 3-4 patterns of the tree species configuration with reason. This research is severed as of the theory basis and practice guidance of the ecological safety system construction and protection, we expect it come into the forest ecology system holding the central character and the thick culture background.
