摘要/Abstract

摘要： 从土壤-植被系统(SVS)尺度研究评价了湘西北女儿寨小流域马尾松天然林(Ⅰ)、杉木人工林(Ⅱ)、杜仲人工林(Ⅲ)、油桐人工林(Ⅳ)、润楠次生林(Ⅴ)、毛竹杉木混交林(Ⅵ)及荒草灌丛(Ⅶ)等7种典型植被模式的综合恢复效应。研究表明:建立了涵盖植被、土壤及地形地貌3类因子60个指标的植被恢复综合效应评价体系; 不同模式植被恢复效应总体以润楠次生林最优,荒草灌丛最差,植被子系统、土壤子系统和土壤-植被系统恢复效应灰色关联排序由大到小依次分别为Ⅴ、Ⅱ、Ⅰ、Ⅳ、Ⅵ、Ⅲ、Ⅶ,Ⅴ、Ⅵ、Ⅱ、Ⅶ、Ⅳ、Ⅲ、Ⅰ和Ⅴ、Ⅱ、Ⅵ、Ⅰ、Ⅳ、Ⅲ、Ⅶ; 评价指标关联排序表明,Shannon-Weiner指数、毛管孔隙度、有机质、蔗糖酶活性分别是植被、土壤物理、土壤化学、土壤生物学指标中与土壤健康关系最密切的4个指标; 地形因子对恢复效应的贡献大小排序为坡位、海拔、坡度、坡向。

Abstract: Based upon the case of Nverzhai watershed in northwest Hunan, integrative effects of seven typical vegetation restoration patterns had been studied from the scale of soil vegetation system(SVS)in this paper, which included P. massoniana natural forest(Ⅰ), C. lanceolata plantation(Ⅱ), E. ulmoides plantation(Ⅲ), V. fordii plantation(Ⅳ), M. pingii secondary forest(Ⅴ), P. edulis-C. lanceolata mixed forest(Ⅵ), wasteland-shrub(Ⅶ). Firstly, soil health evaluation system had been found which contained 60 indexes belonging to vegetation subsystem, soil subsystem and topographical factors. Secondly, the gray incidence ordinations of vegetation restoration effects on vegetation sub-system, soil sub-system and soil vegetation system were Ⅴ>Ⅱ>Ⅰ>Ⅳ>Ⅵ>Ⅲ>Ⅶ, Ⅴ>Ⅵ>Ⅱ>Ⅶ>Ⅳ>Ⅲ>Ⅰ and Ⅴ>Ⅱ>Ⅵ>Ⅰ>Ⅳ>Ⅲ>Ⅶ respectively, which proved that pattern Ⅴ was the best and the pattern Ⅶ was the worst. Finally, through the gray incidence arrangement of evaluation indexes, Shannon-Weiner index, capillary porosity, organic matter, sucrase activity had the closest relationship with soil health respectively in vegetation characteristics, soil physical, chemical and biological properties. The contribution rate regularity of topographical factors affecting vegetation restoration was slope position, elevation slope degree, slope direction.
