吉林省城市建设用地投入效益分析

Analysis on the Benefits of Jilin's Urban Construction Land Input

从经济效益、社会效益和生态环境效益3个方面构建城市建设用地投入效益分析指标体系,并以吉林省8个地级市为研究对象进行实证研究。结果表明,吉林省城市建设用地投入的水平特征表现为:投入低效,内在经济、社会、生态环境系统耦合协调水平低下;空间特征表现为:空间分异情况并不明显,但总体来说西北部地区大于东南部地区;建设用地投入效益从大到小依次为经济效益(3.072 1)、社会效益(2.909 5)、生态环境效益(2.532 2),反映吉林省重经济、轻生态的错误发展观念。
