[Abstract]:Urban green space plays an important ecological role in improving urban ecological environment and participating in urban material and energy cycle and renewal. Green infrastructure uses external land protection and internal open space network identification, protection and long-term management of the combination of measures for the urban green space protection strategic protection countermeasures. In this paper, the concept of green infrastructure is introduced to judge the green infrastructure in Wuhan. The vegetation information is extracted from the remote sensing image, and the green infrastructure is extracted to connect the corridor to estimate the green quantity. The distribution of total green quantity, the distribution of connecting corridor network and the characteristics of green quantity in the study area are analyzed. The main contents and conclusions are as follows: (1) regression analysis was carried out between the measured Lai values of community and the vegetation index extracted from ETM remote sensing images. The best fitting regression equation model was RVI- 0.508 2.061 x-0.207x2 0.012x3r20.26km2) the total area of the study area was about 8588.3km2, the total green value of the green area was 211.85 脳 108m2 was 3.547, and the green value per unit area of the study area was 2.467. The area of farmland is 4205.937km2, the cover of other greening such as mountains and hills is 1766.94 km2, the total area of water area is 1583.06km2, the area of urban construction land is 1032.43km2, and the farmland in the study area is the main green cover area. The distribution of green quantity grade in the study area is dominated by the low green quantity area, and the overall green quantity level is relatively low. The green corridor area of green infrastructure in the study area is 35.89 脳 10 ~ 8m ~ 2, and the total green volume value is 130.64 脳 10 ~ 8m ~ 2 Lai mean 3.641. Based on the analysis of the green quantity characteristics of different components in the connecting corridor, the Lai green zone of the Lai urban green land in the hilly Lai mountain area was obtained in the Lai waterfront green zone of the hilly area. Among the types of green land connected with corridor, farmland is the largest, mountain is the second, followed by urban green space, hilly and waterfront green belt. 4) the green quantity grade characteristics of different components are compared. By comparing the proportion area and green value ratio of different types of green areas with different grades, it was determined that among the five greenbelt types connected with corridors, the higher green volume level was in hills and mountains. The green level in farmland area and waterfront green belt is in the middle and lower level, while the green quantity level in urban green space is the lowest. (5) 20 typical corridors are extracted, and the Lai mean, maximum, minimum value and different green grade Lai value of each corridor are obtained. The area and green quantity were analyzed. The Lai mean value of No. 1 East Lake -Snake Hill Corridor, No. 2 Fu River Corridor and No. 9 Qinglong Mountain Baiyun Dong Mountain Corridor was higher. The green quantity level is better. (6) the distribution of green infrastructure connecting corridor in different circles is inversely related to the urban construction land growth. The proportion of green corridor area to urban corridor area is 1.16, the proportion of green corridor area to outer ring corridor area is 15.47, and the proportion of outer ring to city area is 83.37. The levels of different circles are increasing by leaps and bounds, with the intensity of urban construction increasing from the outer ring to the inner ring. Corridor area and green quantity decrease sharply. 7) aiming at the green distribution and existing problems of green infrastructure connecting corridor in the study area, the optimization strategy of the overall green quantity pattern is put forward. At the same time, the main urban area within the third ring line is also studied. The optimal model of green quantity distribution is put forward in the three urban and rural urban development areas from the third ring line to the outer ring line in the urban-rural interlaced zone and from the outer ring to the city area.
