基于生态系统服务的附属农用地生态景观模块化设计

Modular Design of Ecological Landscape of Affiliated Agricultural Land Based on Ecosystem Services

  • 摘要: 农用地为人类提供的多元功能很大程度上取决于农用地的生态系统服务功能,对农业生态景观进行科学合理设计是提升农用地生态系统服务的有效途径之一。但是,占据一定面积的附属农用地在现有的农用地生态景观设计中常被忽略。为了有效发挥附属农用地的生态景观效应,增加农用地物种丰富度和相关生态系统服务,以生态系统服务作为切入点,对田坎、田间道路、沟渠和护坡等附属农用地的生态景观设计进行研究,重点研究附属农用地生态景观的模块化设计方法。研究结果提出了5大类10种景观设计模块,并对其生态和景观效应、适用场地和组合应用进行了分析。该设计方法可以在满足农业生产辅助功能的基础上,构建能够提升生物多样性水平,改善农用地生态系统服务价值,同时又能体现地域性特色的农业土地景观。

     

    Abstract: Multiple benefits from agricultural land largely depend on their ecosystem services. Scientific and suitable design of ecological landscape on agricultural land is an efficient approach to improve supply of ecosystem services. However, affiliated agricultural land which occupied a certain area is always ignored in current ecological landscape design. To improve ecological and landscape benefits of affiliated agricultural land, and increase species richness and related ecosystem services, a new modular design was developed based on ecosystem services for affiliated agricultural land, as ridge, field track, canal and revetment. Results developed five groups, involving ten landscape modules for agricultural ecological landscape, and their ecological and landscape benefits, applicable places and combined application were analyzed. Besides meeting basic affiliated function for supporting agricultural production, this ecological modular design aimed to increase biodiversity level, improve ecosystem services, and embody local agricultural landscape with strong reginal characteristic.
