基于理论分析与实证研究的结合 ,探讨了农业景观中潜在景观格局的概念、潜在格局分析单元等理论问题 ;并以新疆石河子垦区的 15 0团场为例 ,用景观多样性、均匀度、嵌块体伸长度、聚集度、形状破碎化、分维数等量化指数 ,对其潜在格局进行了分析 ,与以 1982和 1995两个年度的土地利用现状为分类基础的现实格局进行了比较 .结果表明 ,从潜在格局到现状格局均呈现出有规律的变化 .因此 ,用土壤类型的不同分类单元完全可以作为现实格局变化的绝对基准 . Based on the combination of theoretical analysis and empirical research, this paper discusses the concept of potential landscape pattern and potential pattern analysis unit in agricultural landscape. Taking the 15 fields in Shihezi reclamation area of ​​Xinjiang as an example, this paper uses landscape diversity, evenness, The extensibility, the degree of aggregation, the shape fragmentation, the fractal dimension and other quantitative indices were analyzed, and the potential patterns were analyzed and compared with the actual pattern based on the land use status in 1982 and 1995. Results It shows that there are regular changes from the potential pattern to the current situation, therefore, different taxa of soil types can be used as the absolute benchmark for the change of the actual pattern.
