半干旱区农牧交错带平原景观空间格局分析——以凉城县岱海西岸为例

ANALYSIS OF SPATIAL PATTARN OF LANDSCAPE OF AGRICULTURE AND ANIMAL HUSBANDRY ECOTONE IN SEMIARID PLAIN ZONE taking on western coast of Dai hai lake for example

本文运用景观生态学的原理和方法，借助航片，编制景观生态图（１∶１万），并选取基本参数、空间特征指数，从景观的二维水平方面定时研究了半干旱区农牧交错带平原区景观空间格局，结果表明：该地区以旱地、水浇地、草地为主，居民工矿用地、林地、园地、水域占地为辅的典型农牧景观，斑块表现出显著的非随机格局。人类影响强烈的班块，一般形状规则，边界整齐，廊道连通性好而较规则；反之，形状狭窄。

The ecological map (1∶10000) of landscape of this area has been drawn in this paper based on the principles and methods of landscape ecology with the aid of aerial photographies.The spatial patterns of agriculture and animal husbandry ecotone in semiarid plain were quantitatively studied from two dimension level of this landscape by using some basic parameters and the index of spatial features.The results show the area is a typical landscape of agriculture and animal husbandry which mainly include arid farmland,irragated farmland and grassland,and secondarily include the land occupied by residents,plants and mines,forest,vegitable,garden and waters.The patches appear markable non-random pattern.The shapes of patches that strongly influenced by human being generally appear regular,tidy boundary and their corridors are well and regular;on the contrary,the forms are narrow and the boundary is complex and irregular.
