利用1990年土地详查变更调查数据和2006年的SPOT遥感影像,借助GIS空间分析能力,通过计算土地利用类型动态度、转移矩阵、扩展强度指数分析了慈溪市的城镇用地利用变化的时空特征。研究结果表明:1)慈溪市城市、建制镇、交通运输用地扩展的大部分来源于耕地;2)浒山街道城镇、交通建设用地扩展强度指数大于其他镇;3)建设用地扩展以城区周边的街道镇为主。 更多还原

【Abstract】 Based on the SPOT image of Cixi city in 2006 and the data of land alter-surveying in 1990,spatial patterns and temporal variation of land use change were analyzed.Some analytical indexes such as the land-use dynamic degree model,transfer matrix,growth intensity index were introduced to describe the spatial differentiation of urban land expansion.The research showed that there was a rapid growth of urban land use while significant differences in land use among regions.The urban construction land ... 更多还原
