摘要

应用参与式农村评估法从村级水平对西双版纳大卡老寨农地景观与物种保护关系进行了初步调查与分析。斑块物种丰富度与斑块的平均大小、破碎度和分离度相关性较复杂。由于橡胶、西番莲、砂仁斑块面积的迅速发展,多样性、均匀度有所增加,而以集体林为主的景观优势度下降,景观格局的改变使得物种保护呈现出两种不同结果,一是新增加的斑块类型使物种数增加,提高了农业生态系统的多样性,另一方面则是减少或消失的斑块类型造成物种流失。而森林景观是整个农地景观的重要环节,应严格加以保护和合理利用。

Abstract

The relationship between agrolandscape and species conservation in Daka, Xishuangbanna was investigated and analysed.The result showed that there are complex notable coherency between species richness and average patch area, landscape isolation, as well as landscape fragmentation.The diversity index, dominance and evenness of landscape type diversity are various between 1983 and 1997 . Correspondingly , change of agrolandscape had effect on species conservation.Most of all, forest patch played an important role in the whole agrolandscape.
