| 摘 要： | 采用GIS这一先进的信息技术手段,在研究确立天津市淡水养殖影响因子指标及其权重的基础上,利用IDRISI作为适宜性分析软件,对所有数据进行计算,建立淡水养殖区域适宜性分析模型,得出可开展淡水养殖的区域,并将可规划区域划分为"不适宜"、"比较适宜"、"适宜"和"最适宜"4种类型,期望为水产管理部门制定未来水产养殖发展规划提供科学依据。

| Abstract: | The study selected the evaluation factors of freshwater aquaculture in Tianjin , calculated each factor’s weight with the help of GIS, and constructed the suitability analytical model of freshwater aquaculture in Tianjin. A integrated calculation was conducted using IDRISI, then freshwater aquaculture area in Tianjin was divided into 4 grades in terms of suitability: very suitable, suitable, moderately suitable and unsuitable. The study might give the scientific basis for making aquaculture development plan in future. |
