【摘要】：城市化的快速發(fā)展導(dǎo)致不透水表面大大增加,降低了城市的生態(tài)功能和水文調(diào)節(jié)能力。不透水面作為海綿城市建設(shè)的重要指導(dǎo)指標(biāo),其提取和制圖對海綿城市建設(shè)的規(guī)劃和分析十分重要。基于鶴壁市海綿城市建設(shè)項(xiàng)目的需要,選取2011年Landsat TM遙感影像,采用BP神經(jīng)網(wǎng)絡(luò)分類法,對鶴壁市淇濱區(qū)的不透水面進(jìn)行了分類提取。通過對1∶1 000地形圖的轉(zhuǎn)換得到了地面驗(yàn)證數(shù)據(jù),對不透水面的提取結(jié)果進(jìn)行了驗(yàn)證,得到不透水面提取的總體精度為79.82%,Kappa系數(shù)為0.65。
[Abstract]:The rapid development of urbanization leads to the increase of impermeable surface, which reduces the ecological function and hydrological regulation ability of the city. Impermeable surface is an important guideline for the construction of sponge city. Its extraction and mapping are very important to the planning and analysis of sponge city construction. Based on the needs of the construction project of sponge city in Hebi City, the 2011 Landsat TM remote sensing image is selected and the BP neural network classification method is adopted. In this paper, the surface of impermeable surface in Qi Bin area of Hebi City is extracted by classification, the ground verification data are obtained by converting 1: 1 000 topographic map, and the extraction result of impermeable water surface is verified. The total precision of extracting impermeable surface is 79.82 and Kappa coefficient is 0.65.
