| 摘 要： | 基于遥感、地理信息系统和景观生态学研究方法,对长汀县根溪河小流域侵蚀景观空间格局、景观组成结构特征进行定量分析.结果表明:小流域内景观多样性指数和均匀度指数相对较低,景观总体分离度指数较高;在各侵蚀景观类型中,以微度侵蚀景观类型的优势度最大,但破碎度和分离度最小;强度以上侵蚀景观类型优势度最小,但其破碎度、分离度和分维数最大.

| Abstract: | The eroded landscape spatial pattern distribution,landscape constitute structure and heterogeneity have been analyzed in the small watershed of Genxi River of Changting County,based on the means of the techniques of RS,GIS and landscape ecology.The results showed that the Shannon's diversity index and evenness index are relatively low,and the landscape division index of the whole small watershed is relatively high;the slightest erosion predominates,but its' index of fragmentation and division is the lowest;whereas the dominance index of the strong erosion and the most serious erosion landscape is minimum,but its' index of fragmentation,segregation and fractal dimension is maximums among the 5 types of the eroded landscape in the small watershed of Genxi River. |
