摘要

采用基于AHP法的评价模型，以聊城地区作为研究对象，通过层次分析法计算各项指标权重对各地区的农业生态环境脆弱度计算结果表明，阳谷县、莘县、东阿县地区农业生态环境脆弱度在0.43~0.48之间，属于中度，这些地区生态环境最好；茌平县、冠县农业生态环境脆弱度在0.57~0.60之间，属于中强度，这些地区生态环境较好；高唐县、临清市、东昌府区农业生态环境脆弱度在0.61~0.69之间，生态环境较差；因此在聊城地区应该开展绿色生态屏障体系建设，搭理营造水源涵养林，开发区开展点面治理污染为主的攻坚工程，东昌府区应以创建园林城市为载体的绿色工程城市。

Abstract

The study aims to judge the agro-ecological vulnerability in Liaocheng, Shandong province. With Liaocheng area as the research object, the AHP method is used to confirm the index weight and calculate the degree of the agro-ecological vulnerability in its counties. The of the agro-ecological vulnerability in Yanggu County, S hen County, and Dong’e County fluctuates between 0.43 and 0.48, and belongs to intermediate level, which indicates the best environment conditions; 0.57 to 0.60 in Chiping County and Guan County, less intense level, and good conditions; 0.61 to 0.69 in Gaotang County, Linqing County and Dongchangfu District, intense level and bad environmental conditions. From the above, we know Liaocheng City should establish the green ecological barrier system and conservation forests system, and take actions to fight against the pollution from point to face; and makes the landscape garden city a carrier for Dongchangfu District to be a green city.
