摘要
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。
A beach culture environmental stress evaluation stratification system which contains threelevels is established, including seven two indicators and 37 three indicators. Using gray system analysismethod and the improved TOPSIS method for socio-economic factors and the natural ecological factorsindicators have been calculated, and the Guangxi Beibu Gulf 21 beach culture focus of the ecologicalpressure on the environment were assessed. Evaluation results show that the prolifmudflat area, Luerhuan-dazao estuary beach culture area, Sanniangwan Dafeng EguchiXiniu horn-Malan Island beach culture district, east of Jiangshan Peninsula beach culHarbor beach culture District the highest pressure on the ecological environment.
