摘 要: 采用“压力-状态-响应”(pressure-state-response,P-S-R)框架模型构建工业型城镇生态安全评价指标体系,运用包括极差变换法、层次分析法(analytic hierarchy process, AHP)和熵权赋值法的综合评价模型计算东莞市麻涌镇1998年至2008年的生态安全综合指数r,并对评价结果和原因进行综合分析。研究表明:麻涌镇的生态安全水平在此11年间整体呈较快上升趋势,但也存在各单项指标之间发展不协调、子系统内部各指标之间增长速度差别较大、综合安全指数r短期内变幅过大而可能导致其安全状态不稳定等问题。基于此,提出其可持续发展对策。
关 键 词: 生态评价;工业型城镇;生态安全;评价指标体系;麻涌镇

Abstract: In this paper, an eco-security evaluation index system of industry-based town was constructed by using pressure-state-response (P-S-R) model. The comprehensive index r of eco-security in Mayong town from 1998 to 2008 were calculated by adopting comprehensive evaluation model based on transfer of extreme values, analytic hierarchy process (AHP) and entropy weight method, then the results and reasons were analyzed. It indicated an high-speed upgrade trend of the eco-security level of Mayong town in the 11 years. However, there were a mismatch within every single index and a great difference in comparing the increase speeds of all indexes of subsystems, besides, the amplitude of r was oversize in the short term, which might lead to unstable security conditions. On this basis, the countermeasures of sustainable development were put forward.
Key words: ecological evaluation; industry-based town; ecological security; evaluation index system; Mayong town
