Study on Evaluation of Economical and Intensive Use of Construction Land in Julu County

This paper takes Julu County of Hebei province as a research area, through calculation and analysis of the growth elasticity coefficient of population and urban and rural construction land in Julu County, determines the type of land use trend in Julu County. Through calculation and analysis of the elastic coefficient of the GDP and the growth of construction land, the contribution of the GDP and the growth of construction land, the type of land use trend in Julu County is determined. The calculation results show that the population grew, land use grew, and PEI1 = 0.19 <1, judging that the trend of land use type that matches the population development and construction land changes of Julu County is extensive. Regional GDP grew, land use grew, EEI1 = 9.14> γ (6.02), and ECI1 = 0.93 <1, judging that the land use trend of Julu County is extensive type. Suggestions for intensive use of construction land are raised: (1) Establish and improve the human-land linkage mechanism and incentive and restraint mechanism for tapping potentials; (2) Make the most of idle land; (3) Strengthen dynamic monitoring and early warning of intensive land use.
