生态足迹模型在我国土地可持续利用评价中的应用及启示

近年来,我国土地资源的不合理利用给生态环境带来了诸多负面影响,这使开展土地可持续利用评价研究成为当务之急,而科学发展观和新一轮土地利用总体规划修编工作的开展,为土地可持续利用评价研究提出了新的要求。生态足迹模型是目前可持续发展评价领域的研究热点,为土地可持续利用评价提供了重要途径。该文分析生态足迹模型在我国土地可持续利用评价中的研究现状,指出研究中主要存在评价精度较低、研究内容不全、应用方法单一等不足,并从研究尺度、研究精度、研究内容、研究方法和对土地利用相关政策启示等角度,提出需进一步改进的方向和建议。

Application and Enlightenments on Sustainable Land Utilization Assessment Based on Ecological Footprint Approach in China

Many adverse environmental impacts of the unreasonable land utilization cause the sustainable land utilization assessment to an urgent affair in China.Ecological footprint is a theory and approach which uses land areas transformed from the consumption of natural resources to quantificationally estimate the sustainable development status on different areas,industries and administrative levels and can be used for the sustainable land utilization research.The status of research on sustainable land utilization assessment based on ecological footprint approach in China is analyzed and some problems such as low research precision,half-baked research contents,single research method and imprecise enlightenment for policy are pointed out.Some directions and suggestions on how to improve the sustainable land utilization assessment based on ecological footprint approach are provided in terms of the research scales,precision,contents,methods and land utilization decision-makings in the end.
