Study On The Evaluation Of Land Intensive Use In The Old City Renovation Area Of Jinan City

Currently, China is still at an important period of strategic opportunities, the process ofurbanization is developing at a very fast rate. Though the land for urban construction is in largedemand, the problem of extensive land use is very prominent. A large number of disorderlyspace for development have appeared, now something must be done to open up the source andregulate the flow, explore the potential of the land and we should take the road of landintensification for long. Jinan is one of the central city in the Bohai Sea region, old cityrenovation area of Jinan City has always been the focus of the construction of Jinan City. Thestructure, type of the land for urban construction, and the infrastructure of city can no longermeet the need of city development. Improving the utilization of land resources, realizing theurban land intensification and sustainable development are urgent.On the basis of in-depth study of urban land intensification, based on the old city renovationarea , the article makes intensive land use evaluation, take 2009 as a point in time, combiningwith the planning and developing of land use, analysis the situation of land using of old cityrenovation area in Jinan, establish the system of evaluation of land intensive use, determine theindex weight, use multi-factor comprehensive evaluation method, make a comprehensivedetermination of the degree of the land intensive use in old city renovation area. And then, studyon the potential of land intensive use and make potential estimation of redevelopment project inJinan City using the total score value-limit revision model.Through the above research, the main point of innovation of the article and the conclusionsinclude:(1)We can evaluate the land intensive use in old city renovation area from four aspects: thedegree of land using, the efficiency of land using, the spatial pattern and the sustainability of land.In addition, the degree of land using can be reflected by floor area ratio, building density andpopulation density; the efficiency of land using can be reflected by the level of premium, therational structure of the land using and the rate of idle land; the spatial pattern can be reflected bythe spatial aggregation and the degree of regional coordination; the sustainability of land can bereflected by the ratio of green space, the degree of complete infrastructure and per capita publicfacilities area.(2) Based on the area determined by the control planning, under the direction of principlethat land using, the intensity of land using, function of land using and Benchmark land price should be consistent with each other, we can divide the old city renovation area of Jinan into fourtypes: industrial transformation zone, residential transformation zone, commercial servicetransformation zone and public buildings transforming zone.(3)In intensive land use evaluation, there are three indicators: population density, landvacancy rate and the ratio of green space, which actual values are overall larger than the standardvalue. We should adjust the value, and this provides a basis for the next step to adjust the indexstandard value.(4)Using the multi-factor comprehensive evaluation method, we can come to the results ofthe degree of the land intensive use in old city renovation area, and divide into four degree ofland intensive use. The results show that the degree of land intensive use of the eastern area ishigher than the central and western.(5)The general potential for expansion of land intensive use in the old city renovation areaof Jinan City was estimated. According to the analysis, the old city renovation area of Jinan Citycan still supply 597.78 ha of land; the largest potential for expansion is the Wang guanzhuangarea, Jiluo area, Shanda area, and Maoling mountain area. These areas should be used as the keyareas of the old city renovation area of Jinan City during the second five.(6)According to the total score value-limit revision model, the potential of the project of theold city renovation area was evaluated, the potential divided into three potential level of landintensive use. The result is consistent with the result of the evaluation for land intensiveutilization. The potential of land intensive use in central and western area is bigger than theeastern area. Simultaneously, from the perspective of the rule layer, the paper analyzes the keyaspects for exploring the potential.(7)Next plan has been proposed based on intensive land use evaluation of the old cityrenovation area of Jinan City. Jinan need use land resource reasonable and effective, optimize theland use structure, and advance the industrial structure adjustment, to make effective land use inthe old city renovation area linking with overall land use planning and urban planning. While, wemust strengthen the protection of the old city-commercial port area, establish intensive land useevaluation system.
