建立了包含3个层次的滩涂养殖生态环境压力评价分层体系,包括7个二级指标和37个三级指标。采用灰色系统分析方法和改进的TOPSIS法分别对社会经济因子指标和自然生态因子指标进行了计算,并对广西北部湾21个滩涂养殖集中区的生态环境压力进行了评估,评价结果显示,乌泥滩涂增殖区、鹿耳环-大灶江口滩涂养殖区、三娘湾-大风江口养殖区、犀牛角-麻兰岛滩涂养殖区、江山半岛东侧滩涂养殖区、珍珠港滩涂养殖区对生态环境的压力最高。
The stratification system of pressure assessment on the ecological environment of tidal flats with three levels is established, including seven second-level indicators and 37 third-level indicators. The gray system analysis method and the improved TOPSIS method were respectively used to calculate the indexes of socio-economic factors and natural ecological factors, and the ecological pressure of 21 beaches in Beibu Gulf of Guangxi was evaluated. The evaluation results showed that, Beach breeding area, deer earrings - the large Jiangkou beach farming area, Sanniang Bay - windy estuary culture area, rhinoceros horn - Mulan Island beach aquaculture area, the East Peninsula beach aquaculture area, Pearl Harbor beach aquaculture pressure on the ecological environment highest.
