Study On Appraisement Of Urban Land Grade And Benchmark-price

With the development of our economic systems reformation, especially land's using system reformation, our concept about land'value has changed greatly. Land is not only basic conditions of society substance production, but also large wealth of our society—assets. Our country must check the amount of land resources and land assets, that is the value of land. So land-price evaluation has been necessary to the deep reformation of our land's using system. And with the progress of land using system reformation and town housing system reformation, methods of land's rewardful using has been diversified, which raised higher request to urban land rank and valuation. Station resource department encourage us using computer technology in urban standard land-price valuation, integrating valuation with computer and geography information system. All of this indicate that our country's urban land rank and valuation has entered a new phases. So, how to perfect the theories, methods and measures so that found a reasonable and scientific land-price system, and how to accomplish land-price valuation with the help of computer technology, are a key problem in our present land market.Under the guidance of socialism market economy theory, this paper takes Marxism rent theory and area-position theory, combines land market fact of our country and the update example of leshan city zone land rank and standard land-price, studies and discusses the theories of urban standard land-price valuation and land-price dynamic inspect, and gets a scientific and practical technology methods of evaluating standard land-price1 .Standard land-price systemStandard land-price system comprises some kinds of land-price and related coefficients and indexes. They are different in land-price system, and do function in land market respectively. On the other hand, they are closely contacted with each other, conduct and control land market to keep it ordered and standard. In the past, we often ignore integrality of the system, and there are limitations in valuation results. An integrate standard land-price system should comprise region (rank) standard land-price (concluded classify standard land-price), route price of business land, standard land-price amending coefficient table. Land-price dynamic inspect.2 the meaning of the standard land-priceThe standard land-price is an average price at different time, different land level, different use, in certain period and cubage rate on a natural market .It is uncertain and cannot compare if short of any condition. Therefore, the standard land price have use value and comparable character after we plot the meaning of the standard land-price. The basal meaning of land price include:the evaluate norm day, the term of the use of land, the standard cubage rate and the degree of the land exploitation etc.3 Route price of business landIt is obvious to characteristic of city zone business land locating with street, in order to making up the lack of using business land rank standard land-price to show the land contrast of business land, fill reflecting characteristic of business land locating with street, offering advantage for a piece of land price evaluation and management in future. So it is necessary to evaluate business land route price in the work of standard land-price evaluation.A intact Route price system should include Route price, standard depth and amending coefficient table.Route price is the core of all Route price system, It is correlative Pith Route price section, the example number of section and amending coefficient.The standard depth is an important factor that affects the route price. Whether the confirm of the standard depth is reasonable effects the route price straightway. when we confirm the standard depth we should think over the practice of the city.The table of correctional modulus includes the correct of depth, the correct of cubage rate and the correct of cri ti cal width etc. only through constituting a cooperate of a perfect table of correctional modulus and route price can we use route price in the land evaluation .At the same time we should understand the essential difference and relationship between the anterior and behind correctional system meanings.4 the model way to evaluate the standard land-priceIt is always the direction of land workers to enrich the ways of land evaluation and evaluate standard land-price scientifically and rationally. This paper discuss the land-price level model and land-price separate model that adapt to the market of leshan combined with the practice of z i bo. What's more, it plays an important roll in the synthetically confirm the standard land-price and establishes a good base for the evaluate work in the future.5 the land-price dynamic inspect modelThe market of the land is a dynamic market, the land increments incessantly with the development of the society economy and the land market. the level of land-price varies incessantly, and the fruits of the standard land-price reflect the level of land-price at some time; when the land market varies or the ingredients of effecting land-price varies we must update the standard land-price in time to keep the fresh of the standard land-price and reach the goal of land-price dynamic inspect. This paper constitute the land-price inspect system combined with the practice of leshan and brings forward. the Method of land-price dynamic inspect to combining land-price dynamic inspect model and land-price index. 6 land-value evaluation system The work of urban land evaluation involved wide area, and the procedure of this work is very complicated. It needs large number of data(both includes large numbers of graphics data and property data.), the calculate of its data is loaded down with trivial details, the request of its fruit is high. It is the trend of the development of land market to complete the work of the evaluation of land by using of the technology of computer. Therefore, it is very important to establish a scientific, simple and convenient, and applied land evaluation and management system .This paper takes the software of geography information system Mapinfo as the flat roof, take Mapbasic as the programmer language to exploit the land-value evaluation and management information system. This system can expediently, intuitively and effectively manage the graphics data and property data synchronistically; it takes the structure of modularization to complete the program exploitation .It is easy to extend and transplant. It brings a good base to contact with other systems in the future. At the same time the interface of this system is friendly, it is simple to operate it and convenient to use it.
