Analysis On The Influence Of Land Resources On Economic Carrying Capacity In Shijiazhuang

Land is an important carrier of all the resources and the environment.So solving the contradiction between people and land,improving the land utilization efficiency,realizing the importance of sustainable development of land resources will improve the bearing capacity of the city's rapid economic development and social economy significantly.Based on the study of the concept of carrying capacity,I try to define economic carrying capacity as a region in the existing population,resources,ecological and social and economic development under the condition of optimum economic scale of all production factors combination can withstand,the matching degree represents a region's economic development speed and the actual the situation,and the gross domestic product GDP as the research index of economic carrying capacity.Based on the related theory,on the basis of the previous achievements,the integrated use of descriptive statistics and inferential statistics,studied the influence on the present situation of land resources utilization in Shijiazhuang city and the economic bearing capacity.This article tries to establish land resources utilization evaluation index system,including 5 level indicators,20 level two indexes,from five aspects of the comprehensive consideration of various factors who have significant influence on the use of land resources including the productivity,production stability,economic feasibility,resource protection,social acceptability.According to the index system,the article makes a comparative analysis of the seven cities,including Handan,Shijiazhuang,Baoding,Tangshan,Taiyuan,Zhengzhou and Ji'nan,according to the comprehensive evaluation result shows that there are many problems in the aspects of land use in Shijiazhuang city.According to the relevant theory of economic development,the article tries to construct the calculation model of GDP,by 1996-2012 years in Shijiazhuang City,relevant indicators of GDP and land resources as the sample data,using the Eviews software to establish the regression model,and the related index of the data in 2013 and 2014 for two years into the model to estimate and compare the value and the actual value of the GDP.The results of comparative analysis show that the calculation value and the actual value of the difference between the ratios of-1.27% and-2.21%,on the one hand it shows the model error is small,the model is feasible;on the other hand,the predicted values are less than the actual value,Shijiazhuang city clear in the use of land resources there are still some problems,the development of economy there are certain restrictions.Therefore,improving the efficiency of land resource utilization and realizing the sustainable development of land use can promote the economic carrying capacity of Shijiazhuang and speed up the development of economy.
