Study On The Assessment Of Land Use Structure And Its Change Mechanism Of Yingkou High-tech Industrial Park

Rational land use structure which belongs to a certain scope of the land is playing a larger a prerequisite for economic benefits.With the rapid social development, the study about rational land use structure has become the focus of research.Now as an integral part of"five points and one line"of Liaoning Province and along with a good opportunity that is "revitalizing the northeast old industrial base,"Yingkou city is in a period of rapid economic development.Yingkou High-tech Industrial Park as an important economic growth point of Yingkou city,study on the rationality of land-use structure has an important significance for the development of both parks and Yingkou City.In this paper, doing deep study on land use structure of Yingkou High-tech Industrial Park by collecting park's information about land use from 1994 to 2008,using phased evaluation of land-use structure and calculating reasonable degree of land-use structure from 1994 to 2008,so analying the change trend of land use structure of Yingkou High-tech Industrial Park.Through phased evaluation of land-use structure, selecting the rate of industrial land, land use rate of high-tech industries, rate of business taking,rate of residential land and roads coverage,rate of parks and green cover these six indicators, establishing an evaluation system,using Ritter Philippine law, analytic hierarchy process method to determine the weight of evaluation index,score of land use structure of three stages are 58.40,77.13,63.60.In addition, use the method that is improved TOPSIS to measure the reasonable degree of land-use structure from 1994 to 2008, obtained scores of the reasonable degree of the past 15 years, showing that score of the reasonable degree of land-use structure is an upward trend year after year.The land utilization in spatial layout is also analyzed.The results of study on land-use structure by using the above two methods are described Yingkou High-tech Industrial Park land use structure which is consistent with the park's location. The park mainly for industrial land,based industrial park land proportion of the total area is 58.28%.But business land and housing land, park and green area is lesser,though it has smaller impact for the park's overall structure, from the perspective of the park's future development ,it should be appropriately increased the proportion of these sites, improve the basis for park facilities, optimize investment environment in the park. This study is aimed at the in-depth study on the land use structure in development zones. Phases evaluation of the park is aimed at builted land use structure, to analyzes its reasonable evaluation;, measuring the reasonable degrees in every year is aimed at the overall level, with phase evaluation.With the actual situation Yingkou High-tech Industrial Park with of land use status and results of land evaluation of intensive utilization,it shows the results of these two methods is more reliable, can provide certain reference value for the land use in the park.
