| 摘 要： | 应用Arc GIS判读2011年的合肥遥感影像,提取各类型廊道信息。研究区面积为11 429.68 km2。结果表明,合肥市的绿色廊道中,道路绿色廊道长度为15 040.28 km,面积为416.79 km2,密度为1.32 km/km2;河流绿色廊道长度占绿色廊道总长的12.2%,面积占14.3%;环带总长度为687.21 km,总面积为19.78 km2。绿色廊道网络面积为554.49 km2,约占研究区面积的4.86%。另外,城市绿色廊道的网络格局较为单一,还有待进一步优化与改善。

| Abstract: | Arc GIS was used to interprete the remote sensing image of Hefei City which had been taken in 2011,and extract the information about various types of corridors. The study area is 11 429. 68km2. The results indicated that among the green corridors in Hefei City,the green roadcorridor is 15 040. 28 km in length,416. 79 km2 in area,and1. 32 km / km2 in density; The green river corridor occupies 12. 2% of total green corridors in length and 14. 3% in area; The green belt were 687. 21 km in length,19. 78 km2 in area. The total green corridor network was 554. 49 km2 in area,which takes up 4. 86% of the study area. Besides,it was found that green network landscape pattern is unitary in structure,which waits for further optimization and improvement. |
