8.5. 1. 1 Current situation of commercial and service land
Commercial and service places include commercial places, financial and insurance places, restaurants and hotels, and other commercial and service places such as office buildings, commercial buildings and travel agencies. Figure 8. 17 reflects the location and distribution of commercial gold lots in Hangzhou urban area. It can be seen that commercial and service land is densely distributed around the old city. The distribution of commercial service land in each district is the largest in Xihu District, followed by Xiacheng District and Jianggan District. The total area of West Lake District is 28.5426km2, of which commercial service land accounts for 1.5045km2, which is distributed around West Lake in space. The commercial service land in Jianggan District is mainly distributed along Taoqiu North Road and Genshan Road. Binjiang District and Xiaoshan District, newly merged into Hangzhou, have less commercial service land, only 0.0607kmz and 0. 1802km2 respectively.
8.5. 1.2 Present situation of industrial, mining and storage land
Most industrial, mining and storage sites are far away from tourist attractions and historical sites. In the old city, it is mainly distributed in Gongshu District and Xiacheng District, with an area of 6.22490km2 and 5.7450km2 respectively, most of which are located in the north of Gongshu District and Xiacheng District. The banks of the Beijing-Hangzhou Grand Canal in Gongshu District are the main gathering places of industrial and mining storage facilities. Secondly, Shangcheng District in the south of Jianggan District and the north bank of Qiantang River are also concentrated distribution areas of industrial and mining storage, mainly distributed on both sides of railways and waterways. For example, a large area north of Genshanmen Station is mostly used for industrial and mining storage. The newly merged industrial and mining storage land in Xiaoshan District of Hangzhou is 1 1.3944km2, accounting for 32% of the existing industrial and mining storage land in Hangzhou. It shows that the historical evolution characteristics of industrial, mining and storage land in Hangzhou are obvious (see Figure 8. 17).
8.5. 1.3 Present situation of land for public facilities
Here mainly refers to historical sites, scenic spots, parks, squares, public green spaces and so on. West Lake Scenic Area is the largest land for public facilities in Hangzhou, and there are scattered land for public facilities in other districts. According to the statistical results (Table 8.2), the land for public facilities in Xihu District is 9.0908km2, and the total land for public facilities in other districts is 5.07km2, which is only a little more than half of the land for public facilities in Xihu District. This situation shows that on the one hand, it is necessary to protect and develop the existing land for public facilities, on the other hand, it is necessary to vigorously develop new land for public facilities, so as to help the city develop in the direction of ecological garden city more quickly.
8.5. 1.4 * * Status of construction land
The land for public buildings mainly refers to the land for government organizations, education, scientific research and design, culture and sports, medical and health care, charitable organizations and so on. The zoning phenomenon of public construction land in Hangzhou is obvious, and the types of public construction land in Jianggan District, Gongshu District and Xiacheng District are relatively concentrated. The land for education and scientific research in Xihu District is obviously more than that in other districts, reaching 3.484km2, accounting for 26.4% of the land for public buildings in Hangzhou, mainly distributed in high-tech development zones. Binjiang District has the least land for education and scientific research, only 0.2 135km2, and the total land for public buildings is only 0.2509km2, which has great development potential (see Table 8.2).
8.5. 1.5 current situation of residential land
The city is one of the human settlements, and living is the first activity of the city (Li Dehua, 200 1), which shows the important role of residential land in the city. From the aerial interpretation results of urban land (Table 8.2 and Figure 8. 17), residential land is the most common type of urban land in Hangzhou, in which urban single residential land is the main one, with an area of 28.0 159km2, while urban mixed residential land only accounts for a small proportion, only 0.1kloc-0. In addition, in Xiaoshan District and Binjiang District, two newly expanded urban administrative districts and Jianggan District, rural residential land still accounts for a large proportion. The areas of rural residential land in the three districts are 17.6639km2, 8.7526km2 and 6. 18 12km2 respectively. At present, the total area of rural residential land in the seven districts is 39.7 192km2 (Table 8.2), which exceeds the area of single residential land in cities and towns. There is great potential for unified planning and transformation of these areas, building new houses and improving land use efficiency. This is an important reserve land source for the future development of the city.
8.5. 1.6 Current situation of traffic land
The formation and development of cities are closely related to the formation and development of urban traffic. The traffic land in Hangzhou is basically in the direction of east, west, north and south, the traffic road density is increasing towards the city center, and the main traffic roads extend radially outward, and the layout is basically reasonable. The total traffic land area of seven urban areas is 22.3623km2, accounting for 13.6% of the total construction land area in Hangzhou (see Table 8.2 and Figure 8. 17).
8.5. 1.7 Present situation of special land use
The special land in Hangzhou urban area is mainly military facilities and religious land, with a total area of 4.8643km2, accounting for 2.96% of the total urban construction land area, mainly distributed in Jianggan District (see Table 8.2 and Figure 8. 17).
