【摘要】：城市土地利用绩效评价及其障碍度诊断是实现城市土地可持续利用的重要依据。以大庆市为研究区,构建基于土地投入水平、土地利用程度、土地利用效益、土地利用生态可持续性的城市土地利用绩效评价指标体系,采用改进TOPSIS模型评估大庆市在2001—2010年的城市土地利用绩效状况,并运用障碍度模型分析诊断其障碍因子。结果表明,十年间大庆市城市土地利用绩效呈现上升态势,绩效指数从2001年的0.290 0增加到2010年的0.715 4,城市土地利用绩效由低级水平发展到良好水平;土地利用程度和土地利用生态可持续性的障碍度总体呈增长趋势,年均速分别为1.91%和1.38%;土地利用效益和土地投入水平的障碍度总体呈减少趋势,年均速分别为2.52%和0.76%;土地利用程度对未来城市土地利用绩效的影响最大,提高土地利用程度对促进城市土地利用绩效提升至关重要。
[Abstract]:The evaluation of urban land use performance and the diagnosis of its obstacle degree are the important basis for realizing the sustainable use of urban land. Taking Daqing City as the research area, the evaluation index system of urban land use performance based on land input level, land use degree, land use benefit and land use ecological sustainability is constructed. The improved TOPSIS model was used to evaluate the urban land use performance in Daqing city from 2001 to 2010, and the obstacle factors were analyzed and diagnosed by using the barrier degree model. The results showed that the urban land use performance of Daqing City increased from 0.290 in 2001 to 0.715 4 in 2010, and the urban land use performance developed from low level to good level. The barrier degree of land use degree and land use ecological sustainability showed an increasing trend as a whole, with an average annual rate of 1.91% and 1.38%, respectively, while the barrier degree of land use benefit and land use input level showed an overall decreasing trend. The average annual speed is 2.52% and 0.76%, respectively. The degree of land use has the greatest influence on the future urban land use performance, and improving the degree of land use is very important to promote the improvement of urban land use performance.
