贵州省岩溶地区水土资源生态安全研究

Ecological Security Research of Land and Water Resources in Karst Region of Guizhou Province

基于压力-状态-响应（PSR）模型,利用相对距离和层次分析方法对贵州省2007-2012年的水土资源生态安全进行定量化分析。结果表明,2007-2012年贵州省的水土资源压力安全距离和状态安全距离总体偏小,响应安全距离相对较大;总体生态安全属于安全状态,响应安全距离较大是影响总体安全距离的主要因素;水土资源生态安全的最大影响因素是水土资源开发利用的管理。该结果可为贵州省水土资源的可持续利用、生态环境建设和经济社会发展提供借鉴和参考。

With the pressure-state-response （PSR） model, using the relative distance and hierarchical analysis method, the article made a quantitative analysis on the ecological security of land and water resources in Guizhou Province from 2007 to 2012. The results show that the pressure safety distance and safety distance of water and land resources is smaller from 2007 to 2012, and it has a relatively large response safe distance. Overall the safety status belongs to ecological safety, and the response safe distance is the main factors influencing the overall safe distance. The largest influencing factor for ecological safety of water and land resources in Guizhou Province is the management of development and utilization of water and land resources. The results of the study can provide reference for the sustainable use of water and land resources and ecological environment construction and the social economic development.
