喀斯特地区生态-经济-社会系统协调发展评价研究——以贵阳市为例

Study on coordinated development of ecological-economic-social system in Karst region——A case study of Guiyang city

喀斯特地区脆弱的生态环境与经济发展矛盾突出,严重制约了区域协调可持续发展.基于区域协调发展理论和系统理论,借助DPSIR概念模型,构建区域协调发展评价指标体系,以贵阳市为研究对象,对其1992～2011年协调发展程度进行综合评估.结果表明,贵阳市生态指数呈波动变化、经济指数和社会指数整体稳定上升;协调发展经历了失调衰退经济滞后型（1992 ～ 2000年）、濒临衰退过渡到勉强协调发展经济滞后型（2001 ～2003年）、初级协调发展经济滞后型（2004～ 2006年）、中级协调发展经济滞后或生态滞后型（2007 ～ 2011年）的演化轨迹,经济的相对滞后曾一度是三者协调发展的限制因子,但从长远发展看,生态系统脆弱且敏感性显著等问题一直存在,生态环境将是三者协调发展的一个主导制约因子.最后,提出贵阳市协调发展的对策与建议.

The fragile ecological environment and economic development of the outstanding contradictions has badly influenced harmonious and sustainable development in typical karst region.In this paper,taking Guiyang as example,On the basis of regional coordinated-development theory,systems theory and the driving force,pressure,state,impact and response （DPSIR） conceptual framework,a coordination development evaluate index system was constructed.We also assessed the degree of coordination development in Guiyang city from 1992 ～ 2011.Results show that the trend of economic and social index has increased,but ecological index presented a fluctuated trend; The coordinated development has experienced the evolutionary track of the imbalance recession and economy lagged （1992 ～2000）,from near recession to barely coordinated development and economy lagged （2001 ～2003）,elementary harmonious development and economy lagged （2004 ～ 2006）,medium harmonious development and economy lagged or environment lagged （2007 ～2011）.However,Economic lag was the limiting factor of the coordinated development of ecological-economic-social System once,from a longterm perspective,ecosystem is vulnerability and sensitivity of the significant,The ecological environment lag will be a dominant factor restricting coordinate development.Finally,countermeasures and suggestions for coordinated in the study area are proposed based.
