【摘要】 生态安全是可持续发展的基础,土地资源生态安全评价是土地资源可持续利用研究的前沿课题。以济南市为例,从自然、经济、社会3个方面建立了由20项指标构成的土地资源生态安全评价指标体系,用层次分析法(AHP)确定指标权重,并用数学模型计算土地资源生态安全评价值,将生态安全划分为5个判别等级,对济南市2004年和2007年的土地资源生态安全状况进行了综合评价。研究结果为:济南市2004年和2007年土地资源生态安全值分别为0.6755和0.6818,2007年比2004年土地资源生态安全状况虽稍有好转,但仍处于"一般"的安全状态。更多还原

【Abstract】 Ecological security is the basis of sustainable development.Ecological security assessment of land resources is a forefront research topic of sustainable utilization of land resources.Taking Jinan city as an example,an index system of twenty indicators on ecological security of land resources,including natural,economic and social aspects,is established.Using AHP method to determine the index weights and mathematical models to calculate ecological security values of land resources,based on security values being devided into five grades,ecological security of land resources in Jinan City in 2004 and 2007 are comprehensively evaluated.The results show that ecological security values of land resources in Jinan city in 2004 and 2007 are 0.6755 and 0.6818 respectively.Although ecological security of land resources in Jinan city in 2007 is better than that in 2004,all of them are in the state of "general".更多还原
