Study On The Scale Control Question Of Construction Land

China's population is increasing instantly, and its city scale is also enlarging. The further acceleration of the pace of urbanization causes the extension of the construction right-of-way area. The contradictions between the ever increasing of construction right-of-way area and the decreasing of the farming land area becomes obviously. We must control the total area of the construction right-of-way because of the problem of survival and development. We should pay much attention to the intensive land and the intensive discover potentials. The demand prediction of the construction right-of-way is the core of the whole land project. It is also the evidence of the land management. On the basis of the reasonable assessment and prediction of the increasing demand of the construction right-of-way, and also on the basis of the scientific programming of the land resource, it is of great importance to the whole country's long stable economy development. The main factors of influencing the construction land are population, industrial structure, the situation of the economy development, etc. By analyzing the current situation of the construction land in Yining, we can find out what the problem is as well as its reasons. After analyzing its impact elements, on the basis of the presenting data, the exponential smoothing method, the prediction of production function and of linear returning were chosen to make a prediction of the construction land in Yining. It can define the land scale there. The solid train of thought was proposed to control its scale. The protection of cultivated land is the premise of urban and rural development, and should implement "ex-situ conservation." Regional urban construction sites in overall control; intensive land use, improving the urban land use system, the implementation of per capita land for urban construction standards.At last, the measure and suggestion of controlling the city construction right-of-way in Yining is proposed.
