摘要/Abstract

摘要： 利用植被景观类型图,获得面积、周长、景观斑块的长、宽等信息,对庞泉沟保护区核心区的植被景观特征进行分析。结果表明,核心区景观及斑块分布具有明显的地带性;核心区景观多样性较小,均匀度较低。另外,本文尝试用长宽比、伸张度、圆环度和周长与长轴的比这四种指数对景观斑块的特征进行了分析。结果表明,这四种指数在景观特征分析中具有一定的生态学意义。

Abstract: The characteristics of the vegetation landscapes in the core area in the Natural Reserve of Pangquangou were analyzed by the acreage, the perimeters, the lengths and the breadths, which were obtained from the map of the vegetation landscape types, of the landscape patches. The results show that the distribution of the landscapes and the patches are obvious belt-quality. The diversity and the evenness of the landscape are low. In addition, four indexes, which are the rate of the length and the breadth, the elongation, the circularity, the rate of the perimeter and the length, were tried to analyze the characteristics of the patches. The results show that the four indexes are definite ecological meaning in the analysis of the landscape characteristics.

Key words: vegetation landscape, patch, Landscape-diversity
