【摘要】 利用3S技术研制的哈巴河流域的土地利用现状图,采用多样性指数、优势度指数、破碎度指数和分离度指数对哈巴河流域高山峡谷景观空间格局进行分析评价.结果表明,流域的整体生态环境良好,中下部地段的土地利用程度较高,景观破碎程度大,上部利用程度低;现行土地利用格局不尽合理,需要进行结构调整.更多还原

【Abstract】 The map of present landuse in Habahe watershed was drawn by GIS.Four indices,i.e,Diversity,dominance,fragmentation and isolation were chosen to evaluate spatial structure and present of landuse in Habahe watershed.The results indicated that eco-environment of Habahe watershed was relative good,landscape was comparatively fractual under the middle of watershed but top was exellent.The structure of landuse is not rational and should be adjusted.更多还原
