| 中文摘要: |
| 基于P-S-R 模型构建土地生态安全评价指标体系，并结合熵权法和特尔斐法测算各指标权重，
根据综合指数界定土地生态安全等级，对贵州省2005—2012 年土地生态安全进行了评价。结果表明：2005—
2011 年，贵州省土地生态安全综合指数从0.7149 上升到0.7970，安全等级为较安全；2011—2012 年，土地生
态安全综合指数从0.7970 上升到0.8070，安全等级从较安全上升到理想安全。但是人地矛盾突出、自然灾害
频繁、人均收入有待提高、财政收入整体水平仍较低、生活垃圾处理量较低、化肥使用量较高等仍是贵州省土
地生态安全的较大隐患。 |
| 英文摘要: |
| Based on P-S-R model，this paper evaluated the index system of land ecological security，estimated the
index weight by entropy weight method and Delphi method，and according to the comprehensive index of land ecological
security level，evaluated the land ecological security of Guizhou province in 2005 to 2012. The results showed that，in
2005-2011，the comprehensive index of land ecological security in Guizhou rose from 0.7149 to 0.7970，the security
level was relatively safe；in 2011-2012，the comprehensive index reached 0.7970，the security level desired safer. But
the land ecological security of Guizhou still had risks，like obvious contradiction between people and land，frequent
natural disasters， per capita income to be improved，low overall level of revenue，low amount of municipal solid waste，
high fertilizer use. The result could provide a reference for the sustainable socio-economic development in Guizhou
province. |
