甘肃省古浪县土地利用与社会经济协调度评价

土地利用与社会经济协调度评价对指导区域土地利用和社会经济发展具有重要意义。参照协调度与协调发展度的相关概念,从土地利用与社会经济两个方面建立综合评价指标体系,并构建评价模型,对甘肃省古浪县2000—2008年土地利用与社会经济的相对和绝对协调度及协调发展度进行了定量测算。研究结果表明,古浪县的相对协调度等级变化较大,2001,2002和2006年属于社会经济快速发展型,2003年属于土地利用倒退型,2004—2005,2007—2008年属于土地利用快速发展型;绝对协调度等级较高,2000年属于中级协调,其余年份协调度等级属于优质协调;协调发展度呈现逐年上升趋势,由轻度失调社会经济滞后型上升到了良好协调土地利用滞后型。

Evaluation of Coordination Degree Between Land Use and Socio-economy in Gulang County of Gansu Province

The evaluation of coordination degree between land use and socio-economy is of great significance to guide the development of land use and socio-economy in a region.The index system and model for an com-prehensive evaluation of land use and socio-economy in Gulang County were constructed by referring to the concepts of coordination degree and coordinated development degree.Accordingly, aquantitative assessment was made for the relative/absolute coordination degree and coordinated development degree between land use and socio-economy from 2000to 2008in the county. Results from the research indicated that the change in the grade for relative coordination degree was greater, which belonged to the models of rapid economic devel-opment in 2001, 2002and 2006, retreated land use in 2003, and rapid land use development from 2004to 2005and 2007to 2008.The grade for absolute coordination degree was high, which belonged to the models of intermediate coordination in 2000and high-quality coordination in the other years. The coordinated devel-opment degree showed an upward trend year by year and underwent a transformation from the model of the slight maladjustment with a socio-economy lag to the model of the good coordination with a land use lag.
