【摘要】：采用不透水地表可定量化研究城市空間變化和擴展。本文選取2013年、2014年、2015年成都地區(qū)高分一號影像,通過線性光譜混合分解模型和水體掩膜運算提取成都市不透水地表。以成都主城區(qū)和南部新城區(qū)各區(qū)為單位,分析了不透水地表在空間格局分布和時序變化上的特點及其與主要經(jīng)濟指標的關系。結果表明不透水地表與成都市城市化,特別是經(jīng)濟發(fā)展與工業(yè)固定投資呈正相關,其對城市規(guī)劃建設、洪澇災害預防有一定意義。
[Abstract]:Using impermeable surface to quantitatively study urban spatial change and expansion. This paper selects 2013, 2014, 2015, Chengdu area high score 1 image, The watertight surface of Chengdu was extracted by linear spectral mixed decomposition model and water mask operation. The characteristics of spatial pattern distribution and temporal change of impermeable surface and its relationship with main economic indexes are analyzed. The results show that the impermeable surface is positively related to urbanization, especially economic development, and fixed investment of industry in Chengdu. It has certain significance to urban planning and construction and flood prevention.
