Abstract:

Urban planning construction land standard is the technical specification for allocating various types of urban construction land scientifically, and is the basis for drawing up and revising the overall urban planning as well. In view of China's current urban planning construction land standard, there are many problems such as the big gap of land use control threshold, the lack of regional differences in climate revision, and ignorance of the topographical and geomorphological factors. To solve these problems, this paper proposed a step-by-step process framework and quantitative calculation method for the establishment and revision of standards in accordance with the principle of "total-structure" control. Through the setting of conditions, a universal basic standard for construction land was established. Then quantitative analysis was made for the relations between each index and the basic standard with the selected key indicators such as urban population size, sunshine spacing coefficient, valley area (intermountain basin) width and terrain slope. Finally we formed a revision standard for climate, topography and geomorphology which is matched with the basic standard. The main results are as follows: (1) The per capita construction land area of 95 m 2/person can be used as the total indicator for the basic standard of urban planning in China. The percentage of corresponding per capita for each type of construction land is 32.5% for residential land, 7.42% for public administration and public service land, 22.5% for industrial land, 17.5% for transport facilities, 12.5% of green land, and 7.58% of other types of land. The results of revision value of urban population scale shows that the impact of population size difference on the per capita construction land is relatively weak. (2) The climate revision results of per capita residential land and per capita construction land in major cities show that the climate revision value varies greatly between northern and southern China. The climate revision value of the per capita area of construction land varies by latitude as follows: the figure for 20° north latitude is 93 m 2/person; the figure for 30° north latitude is 97 m 2/person; the figure for 40° north latitude is 103 m 2/person; and the figure for 50° north latitude is 115 m 2/person. The basic standard value of 95 m 2/person is roughly distributed along the Xiamen - Guilin - Kunming line. (3) The cities located in mountainous areas, hilly valleys or intermontane basins can reduce the allocation of community parks and comprehensive parks when the average width of river valley or intermontane basin is less than 2 km. When the average width of the valley or intermontane basins is between 2 km and 4 km, the allocation of the comprehensive parks can be reduced. The revised results of per capita land for construction use on slopes indicate that the terrain slope has a great impact on the revised value of per capita construction land. The revised value at 3° is 3.68% higher than the baseline value, and the increases of 8°, 15° and 25° are 11.25%, 26.49% and 68.47%, respectively.
