Assessment Of Intensive Urban Land Use Potential On Economics

The land is carrier of the social economy development, all economic activities are directly or indirectly the complicated relation with the land. Our country average possessor of land resource is few and land supplies limited, which forces the more economical use land.

The current city landextensive is serious, if it is too extensive in the non- citycentral area land development, it wastes the limited land resource. In certain degree, it is created by the land control policy and the target lack the efficiency.This article analyzes the city land intensive use economicpotential level. First, through the theory discussion, it has analyzed its influence land utilization degree economic agent, which reachs the conclusions that the government pursues is by the region land quality, namely to exterior efficient pursue. The developer pursues is only under the ancestor farmland quality influence ancestorfarmland best volume rate, namely to internal efficient pursue.According to the city overall economic efficiency maximizationprinciple, appraises the city management land the region land bestvolume rate. Then, when establishment appraisal system and method, thesupposition developer in the different city function district to theunit floor space land price investment respectively is a constant, based on this spot, the author proposes the appraisal land intensiveuse potential technical method: Appraise the city land intensive useusing the land synthesis quality level - land price - volume ratelevel relations the important target volume rate level. Finally, in the real diagnosis research department it takes example as Lanzhou, it stated the rational and the technical route based on front, the author calculates the land intensive of Lanzhou city, which uses potential level. It provides the economical instruction for the Lanzhou city in land development using the management and the urban planning establishment. It balances various areas land intensity, and alleviates the city central area the land pressure effectively.
