| 中文摘要 | 论文探讨了华北山地退化生态系统不同植被恢复方式对生态系统服务功能的影响，可为评价植被恢复的生态效应以及植被恢复方式选择提供科学依据和参考。本研究在太行山北段百花山地区的田寺东沟小流域开展，选择小流域内4种不同植被恢复方式形成的群落类型：天然灌木林、人工造林50a形成的人工油松林、人工造林30a形成的人工洋槐林、主动放弃耕作已达25a处于自然恢复状态的退耕坡耕地。研究其生物多样性维持、水源涵养与土壤保持、营养物质保持以及碳贮存5种主要的生态系统服务功能，对植被破坏与恢复过程引起的生态系统服务功能变化进行考察，定量研究退化生态系统不同植被恢复方式对生态系统服务功能的影响与机制。研究结果为：天然灌木林与其余三种植被恢复方式比较，生态系统的服务功能最高，具体表现在：物种多样性丰富、土壤持水性能高、土壤营养功能指数高、生态系统碳贮量最大。两种人工林林型单一、结构简单，群落或生态系统的稳定性差；而退耕坡耕地则自然恢复缓慢。采用接近自然群落的恢复方式将有助于提高人工林的生态系统服务功能。 |
| 英文摘要 | Discussing the effects of different vegetation restoration approaches on degraded ecosystem in the North China mountain area would provide scientific references that estimate ecological effects of vegetation restoration and choices of vegetation restoration approaches.The research region lies at a valley named Tiansi, which belongs to Baihua area, the north of Taihang mountain. Four different types of vegetation are selected. They are natural shrubbery, Pinus tabulaeformis plantations of being planted over 50a, Robinia pseudoacacia plantations of being planted over 30a, sloping farmlands of being abandoned for 25a that are under condition of natural restoration. This thesis study the changes of ecosystem services in the course of vegetation being destroyed and being restored by observing four type functions of ecosystem services which mainly include biodiversity maintenance, water maintenance and soil conservation, nutrients conservation and carbon storage, and also study the ecosystem services effect and its mechanism of the different vegetations restoration approaches in degraded ecosystems. Results showed that:Ecosystem services of natural shrubbery are the highest in four vegetation restoration approaches. Communities and ecosystems of two plantation types are vulnerable, and its forest type and structure are very simple. Abandoned sloping farmlands restore slowly. Adopting the restoration approach which is based on natural vegetation community would be helpful to improve ecosystem services of plantation. |
