成都市城市土地利用結(jié)構(gòu)及效益研究
[Abstract]:In this paper, Chengdu is taken as the research object, according to the situation of the study area, the land use type and area data of Chengdu from 1999 to 2010 issued by Chengdu Bureau of Statistics are collected and sorted out. In addition, according to the statistical bulletin issued by Chengdu Bureau of Statistics, the economic and social development data of Chengdu during this period are collected, and the positive and negative effect method is used to standardize the data, so as to eliminate the influence of units and dimensions on data analysis and research. 1. Using the mature land structure analysis method, through the analysis of land single structure (to calculate the change trend of the proportion of all kinds of land area), the diversity of land use (to calculate the change of all kinds of land types within the system), the information entropy (to calculate the degree of order and disorder within the system), the degree of dominance, the degree of equilibrium, etc., this paper deals with the land types in Chengdu during the 11-year period from 1999 to 2009. The area data is systematically analyzed and integrated. 2. From the overall level, the author evaluates the comprehensive benefits of land use in Chengdu from 1999 to 2010. On the basis of reading and sorting out a large number of previous land use evaluation benefits, the author establishes three indicators of land use economic, social and ecological benefits with the principles of science, systematicness and hierarchy, maneuverability and comprehensiveness. At the same time, based on the mature weight evaluation method, the analytic hierarchy process (AHP) method is adopted. By using fuzzy mathematics and membership degree model, the subjective evaluation and objective evaluation are combined to obtain the weight of each index, and the sum method is used to calculate the comprehensive weight. 3. Using various prediction models, the future change direction of built-up area in Chengdu is predicted by four indexes, and the regression equation is obtained. In order to realize the mutual comparison value of the data, the comprehensive effect of land use is calculated by using the efficiency coefficient method. 4. Finally, the coordination degree model is selected to study and compare the degree of land use coordination in Chengdu in the past 12 years. Through the application of the relevant methods, it can be seen that the area of Chengdu began to expand from 2003 to 2009, especially from 2002 to 2003, and the growth rate decreased slowly from 2003 to 2007. On the whole, the area of Chengdu has been growing in the past 12 years. Among them, the areas of green space in built-up areas, urban areas, public facilities land and industrial land increased by 240.58%, 89.08%, 74.91% and 6928%, respectively. However, the maximum value of land use diversity appeared in 2003, and its diversification index reached 0.69852, the minimum value was 0.6259 in 2000, and the average value was 0.6688. As far as information entropy is concerned, the land distribution in Chengdu is uneven and gradual in this stage. As a whole, the maximum difference is 0.116, which indicates that the overall development of the city is a kind of development mode from disorder to order and disorder. As far as the comprehensive benefit of land use is concerned, there has been a local decline from 1999 to 2000, but after the inflection point of 2000, the land use benefit of Chengdu has shown a gradual upward trend, and with the passage of time, this momentum has become more and more obvious. It increased from 0.2727 in 1999 to 0.8595 in 2010, an increase of 3.15 times on the original basis. In the process of land use in Chengdu, there is a mode of coordinated development as a whole. In addition to the good coordinated development of land use in 2000, it has shown high quality and coordinated development from 1999 to 2010. At the same time, it also means that Chengdu has a high degree of land use, excellent ecological environment and rapid social and economic development. Then the multinomial model is used to predict the development direction of construction land in Chengdu in the future, and the regression equation is obtained. Finally, according to the evaluation results, the results are explained and the optimization suggestions are put forward.
