太行山石质砂岩区封育植被景观及其功能分析

The Hillclosing Afforested Vegetation Landscape and Its Functions in Sandrock Region of Taihang Mountain

通过在太行山典型石质砂岩区 -北京九龙山林场的植被调查和传统与典型取样技术 ,综合阐述了九龙山地区景观特点。在把该区封育植被划分为 4大类型 2 2个群丛的景观元素基础上 ,分析了封育植被景观的结构、类型与物种多样性及地形对格局的影响 ;并通过测定土壤贮水量和径流量两个指标 ,分析了九龙山地区现有封育植被景观格局下的水源涵养和保持水土两大功能。通过该项研究进一步深刻认识了景观的结构与功能的反馈作用关系。

Based on the vegetation investigation and plot technique,the landscape characteristics in Jiulongshan Mountain were synthetically expounded.The hillclosing afforested vegetation was divided into four formations and twenty-two associations.The structures types and species diversity of hillclosing afforested vegetation landscape and the influences of topography on landscape patterns were analyzed.Through measuring the indices of soil water storage and runoff volume,the functions of the conserving water and preserving soil and water of the hillclosing vegetation in the present landscape patten were analyzed.Through this research,the feedback correlation between the structure and function of landscape was further understood.That provides the foundation for the more reasonable plan and management of the soil and water conservation in forest landscape of Taihang Mountain.
