| 摘 要： | 文章以广西北部湾海水养殖区为例，采用模糊数学灰色统计方法与熵权法设置权重，采用TOPSIS建立广西北部湾海水养殖生态环境压力评价体系，并采用Arc GIS软件对广西北部湾海水养殖生态环境进行定量评价。研究结果显示:①海水养殖生态环境压力受养殖模式与时间的影响。②陆基池塘养殖模式对生态环境压力影响最大；浅海筏式养殖模式和浅海网箱养殖模式生态压力居中,浅海养殖模式对生态环境压力影响较小；③滩涂底播养殖模式对生态环境压力全年平均分布，无关键时期。珍珠港湾地区是压力最大分布区，也是生态环境压力的关键点；茅尾海和湾外鹿耳环江至乌雷为次压力分布区，也是养殖对生态环境压力的次关键点；西村到彬塘为三级压力分布区和关键点。

| Abstract: | Taking Guangxi Beibu Gulf mariculture area as an example,the fuzzy mathematics grey statistics and entropy weight TOPSIS method were used to establish the ecological environment pressure evaluation system of Guangxi Beibu Gulf mariculture,and the Arc GIS software was used to quantitatively evaluate the ecological environment of Guangxi Beibu Gulf mariculture.The results showed as follows: 1)the ecological environmental stress of mariculture was affected by the culture mode and species;2)The ecological environment pressure of subgrade pond culture mode was the highest,the ecological pressure of shallow sea culture mode was the lowest,and the ecological pressure of shallow sea raft culture \\ cage culture mode was in the middle;3)The pressure on the ecological environment caused by the bottom sowing breeding mode in the beach was evenly distributed throughout the year,and there was no critical period.Pearl Bay was the area with the greatest pressure distribution,which was the key point of the pressure of aquaculture on the ecological environment;The distribution area of secondary pressure from Maowei and Hehe Bay to Wulei was the secondary key point of the pressure of breeding on the ecological environment.Xicun to Bintang were the third level pressure distribution areas and key points. |
