典型红壤侵蚀景观的时空变化——以福建长汀为例
Spatiotemporal variation of typical red soil eroded landscape pattern: A case study in Changting County of Fujian Province
摘要
Abstract
Based on the 1988, 2000, and 2007 remote sensing images of a typical red soil eroded region ( Changting County, Fujian Province) and the digital elevation model ( DEM) , the eroded landscape types were worked out, and the changes of the eroded landscape pattern in the region from 1988 to 2007 were analyzed with the spatial mathematics model.In 1988-2007, different eroded landscape types in the region had the characteristics of inter-transfer, mainly manifested in the transfer from seriously eroded to lightly eroded types but still existed small amount of the transference from lightly eroded to seriously eroded types.Little change was observed in the controid of the eroded landscape.In the County, Hetian Town was all along the eroded center.During the study period, the landscape pattern index showed a tendency of low heterogeneity, low fragmentation , and high regularization at landscape level, but an overall improvement and expansion of lightly eroded and easy-to-tackle patches as well as the partial improvement and fragmentation of seriously eroded and difficult-to-tackle patches at patch level.关键词
