摘要: 为了描述吉尔吉斯斯坦土壤分布格局及其特点,通过采用GIS和景观生态学方法,选择多种景观指数对吉尔吉斯斯坦土壤进行景观格局特征分析。结果表明:吉尔吉斯斯坦土壤景观斑块数、面积和周长分布均极不均衡,景观趋于严重的破碎形势,各类型间的聚集度较高(AI=89.9),斑块间彼此邻接关系和镶嵌程度较高,景观间具有较高的连通程度,整个景观的分布格局是一个高聚集度、对比度明显、空间分布复杂、异质性较大的土壤景观格局。吉尔吉斯斯坦土壤类型演变主要驱动力为气候、自然环境,而人类活动的作用较小。

Abstract: In order to describe the distribution and characteristics of soil in Kyrgyzstan, choosing a variety of landscape indices to analyze the feature of landscape pattern by using GIS and landscape ecology method. The results showed that, the number of landscape patches, area and perimeter distributed very unevenly in Kyrgyzstan. Landscape fragmentation situation tended to be serious. There was a high degree of aggregation between different types (AI=89.9). The relationship between plaque adjacent to each other and with higher degree of connectivity between landscapes, the distribution of the landscape was a high aggregation degree, in contrast, complex spatial distribution, heterogeneity of soil landscape pattern. Kyrgyzstan soil type evolution is main driving force for climate, natural environment, and the effect of human activity.
