چکیده
Urban planning construction land standard is the technical specification for scientifically allocating various types of urban land, and it basis drawing up revising overall scheme. Considering China’s current standard, many problems exist, such as gap in use control threshold, lack regional differences climate revision, failing to consider topographic factors. To resolve these problems, this study proposed a step-by-step process framework quantitative calculation method establishment revision standards accordance with principle Total-Structure control. By setting conditions, universal basic was established. Quantitative analysis then conducted on relationship between selected key indicators, population size, sunshine spacing coefficient, width river valleys or inter-montane basins, terrain slope, among others. Finally, revised were formed topography, geomorphologic which matched standards. The results are three-fold: (1) per capita 95 m2/person can be used total indicator corresponding single comprises 32.50% residential 7.42% public management service 22.50% industrial 17.50% transportation facilities, 12.50% green space, 7.58% other land-use types. size indicate that difference has little effect amount land. (2) major cities reveal value varies greatly north south China. values area vary by latitude follows: at 20°N 93 m2/person, 30°N 97 40°N 103 50°N 115 m2/person. generally distributed across Xiamen-Guilin-Kunming line. (3) located mountainous areas, hilly valleys, basins reduce allocation community parks comprehensive when average an existing valley basin less than 2 km. When km 4 km, reduced. sloping slope affects Specifically, 3° 3.68% higher value, increase rates 8°, 15°, 25° 11.25%, 26.49%, 68.47%, respectively.

Urban Land-Cover Dynamics in Arid China Based on High-Resolution Urban Land Mapping Products
Rapid urbanization has occurred in northwestern China, threatening the sustainability of its fragile dryland ecosystems. A lack of precise urban land-cover information has limited our understanding on the urbanization in the dryland. Here, we examined urban land-cover changes from 2000 to 2014 in 21 major cities that comprise over 50% of the developed land in arid China, using Landsat Enhanced ...
