煤炭城市土地集约利用评价及其驱动因子分析——以黑龙江省七台河市为例

选取煤炭型城市———黑龙江省七台河市为研究区,从系统角度,基于研究区的经济、社会和生态因素,构建土地集约利用评价的指标体系,运用多因素综合评价法,定量计算和分析七台河市2000—2008年9a间土地利用集约度,并采用SPSS软件对土地集约利用的驱动因子进行主成分分析。结果表明:2000—2008年,七台河市土地利用集约度整体呈上升趋势。2000年和2001年土地利用集约等级属于Ⅳ级,土地利用处于不集约状态;2002—2006年土地利用集约等级Ⅲ级,土地利用处于基本集约状态;2007—2008年土地利用集约等级属于Ⅱ级,土地利用处于集约状态。煤炭产值、人均GDP、城市用地增长弹性系数、工业废水排放达标率、煤炭产量等指标是影响七台河市土地集约利用的敏感因子。

Analysis on Evaluation and Driving Factors on Intensive Landuse of the Coal-base City——A Case Study of Qitaihe City of Heilongjiang Province

This paper selects coal-base city,Qitaihe Cty of Heilongjiang Province as the study area and establishes the evaluation index system of intensive land use from a system point of view,combining the three aspects including economic,social and ecological benefit elements.Then we quantitatively calculated and analyzed degree of intensive land use of Qitaihe City from 2000 to 2008 using the multi-factor comprehensive evaluation method in this study.In this paper,we carried out the principal component analysis method to analyze the driving factors of intensive land use by using SPSS software.The results show that the degree of intensive land use took on an upward trend in Qitaihe City from 2000 to 2008.The level of intensive land use fell into band Ⅳ,and intensive land use was in not intensive state in 2000 and 2001.The level of intensive land use fell into band Ⅲ,and intensive land use was in the basic state from 2002 to 2006.The level of intensive land use fell into band Ⅱ,and intensive land use was in the intensive state in 2007 and 2008.Coal output,per capita GDP,urban land growth elasticity coefficient,allowed level of industrial waste water discharge and coal yield are the sensitive factors affecting intensive land use of the Qitaihe City.
