笔者首先简述农业景观中林地的现状、问题及面临的挑战,论述农业景观中林地在生物多样性保育和多功能应用方面的重要作用,在此基础上,探讨在地块和景观尺度上如何对决定功能的结构进行优化配置,通过农业景观中林地的改造和提升,来促进生物多样性保护和生态系统服务功能提升。研究显示,林地类型、面积、形状、配置结构和树种组成以及在地块和景观尺度上实践的驱动力是决定农业景观中林地功能的重要影响因素。最后,针对农业景观中林地在设计和管护方面,如何实现多功能目标进行了讨论,以期推动农业景观多功能林地的发展,避免把农业景观中林地建成“绿色沙漠”。
筆者首先簡述農業景觀中林地的現狀、問題及麵臨的挑戰,論述農業景觀中林地在生物多樣性保育和多功能應用方麵的重要作用,在此基礎上,探討在地塊和景觀呎度上如何對決定功能的結構進行優化配置,通過農業景觀中林地的改造和提升,來促進生物多樣性保護和生態繫統服務功能提升。研究顯示,林地類型、麵積、形狀、配置結構和樹種組成以及在地塊和景觀呎度上實踐的驅動力是決定農業景觀中林地功能的重要影響因素。最後,針對農業景觀中林地在設計和管護方麵,如何實現多功能目標進行瞭討論,以期推動農業景觀多功能林地的髮展,避免把農業景觀中林地建成“綠色沙漠”。

This paper briefly describes the status, issues and potential challenges facing of woodland in the agricultural landscape. Then, the critical role of woodland and trees scattered in biodiversity maintenance and multiple-use is examined. On this basis, optimize the configuration of the structure, which determine the function of they play, at both site and landscape levels is raised. We argued that by upgrading and enhancing of the woodland throughout agricultural landscape may promote the protection of biodiversity and ecosystem services enhancements. We identified key factors which determining the functions of woodland and trees scattered in agricultural landscape are type, size, shape, physical structure and tree species, as well as their practice dynamics at both field and landscape levels. Finally, aimed at ecosystem services management and project design, how to achieve the multi-purpose plantations are discussed, and some advices are given for promoting the multifunctional woodland development and avoiding becoming“green deserts”.
