1与芬兰农业变化有关的草地中植物种类丰富度和生境连通度的降低显示文摘20世纪中,欧洲半天然草地严重减少,物种多样性降低,这与社会-经济因素密切相关。农业生产的发展驱动着土地利用的变化,从而控制着景观维持生物多样性的能力。本研究中,我们把农业生产变化和景观破碎化、物种多样性联系在一起。结果表明,半天然草地的停止放牧引起了景观结构的显著变化,并使维管束植物种的数目降低。放牧草场数量的下降主要是受与农业政策措施有关的农场水平的经济效果和收益率的影响。自1995年芬兰加入欧盟以来,由于对半天然草地经营有了扶持政策,我们研究地区中放牧斑块的面积又一次增加了。Miska Luoto Seppo Rikolainen Jyrki Aakkula Juha Pykl 王胜 2003AMBIO-人类环境杂志2003,32,7:3
