摘要
对四川省南充市郊农田景观各元素中脊椎动物的生物多样性进行初步研究,结果显示:1.池塘边缘生物的多样性指数和丰富度最高,但生物数量很低.2.蔬菜地物种均匀度最高,且数量也最多.并通过各个景观元素生物群落结构的比较,得出有利于提高生物多样性指数和丰富度的因素,为农田景观的合理设计,保证农业的持续发展提供参考.
The life-form diversity in agricultural landscape was investigated in the suburb of Nanchong City, Sichuan Province from September to October, 2005. The results indicate （ 1 ） In the margin of pond fields, diversity index and abundance are highest, but quantity is lower; （2）Uniformity of vegetable fields are highest, quantity is most. In comparison with biology community＇ structure in agricultural landscape, we have got the ingredients which are propitious to advance species diversity index and abundance. The results have provided reference for design and man- agement of agricultural landscape.
