摘要
土地可持续利用是区域资源环境、经济社会可持续发展的前提和基础。以哈尔滨市市域为研究区,从资源环境协调性、经济可行性和社会可接受性三方面建立了土地可持续利用评价指标体系,运用熵值法计算指标权重,采用灰色关联法计算2001—2008年土地可持续利用水平。结果表明:2001—2008年哈尔滨市资源环境协调性、经济可行性和社会可接受性的变化态势差异显著,资源环境协调性呈大范围波动增长态势,经济可行性呈持续快速增长态势,社会可接受性在小范围内反复波动。2001—2008年间,哈尔滨市土地可持续利用水平总体呈上升态势,2001—2006年为中等可持续利用水平,2007—2008年为较高可持续利用水平。
Sustainable land use is the premise and foundation of sustainable development of both regional resources environment and economy and society.This paper selects the Harbin urban area as the study area and establishes the evaluation index system of sustainable land use from a system point of view combining the three aspects including resource environmental rationality,economic possibility and social acceptability.Entropy method was used to calculate the index weight and the level of sustainable land use from 2001 to 2008 was calculated by the grey relation analysis.The results show that resource environment rationality,economic possibility and social acceptability are significantly different;resource environment rationality is growing with wide fluctuation;economic possibility is rapidly growing;and social acceptability repeatedly fluctuates in a small range.The level of sustainable land use in Harbin urban area is general upward from 2001 to 2008,with medium sustainable utilization level from 2001 to 2006,and higher sustainable utilization level from 2007 to 2008.
