摘要: 以美国LANDSAT/TM遥感数据为信息源,采用分维分析的方法,对珠江三角洲土地利用结构和土地利用变化趋势进行研究。探讨了土地利用类型对空间占据程度、稳定性、变化趋势同分维数之间的关系。结果表明:分维数越高,该土地利用类型对空间的占据程度越大,稳定性越差;反之,则该土地利用类型对空间的占据程度越小,稳定性越强。分维数的变化反映土地利用类型的变化趋势:分维数增大,该土地类型越不稳定,则该土地利用类型扩张,相反,则该土地利用类型缩小。通过具体案例分析,表明分维数及其变化成为土地利用类型结构相关研究的有用指标。

Abstract: As a case study of the land use types of Zhujiang (Pearl River) Delta, they were based on such data sources as LANDSAT/TM. This paper showed that the value of fractal dimension (D) can be used to effectively characterize the degree of spatial occupation, stability of patch types and change tendency of land use. The results indicated that the values of D of land use types were less than 1.50. With the increase of the value of D, the stable degree of the structure and the spatial occupation degree was decreased and increased respectively. Moreover, the D change of certain land use type reflected the change tendency of this type in different periods from 2000 to 2002. When the D of certain land use type increased, its area also increased; conversely, its area decreased. This paper indicates that D and its change have been effective indices towards the researches of the structures of land use types in Zhujiang (Pearl River) Delta.
