基于空间布局优化路径决策模型的山东半岛蓝区海水养殖空间布局优化研究

Marine Fisheries Space Layout Optimization of Shandong Peninsula Blue Area Based on the Space Layout Optimization Path and Decision Model

运用空间布局优化路径决策模型,以2010年为基期,对山东半岛蓝区2020年的海水养殖空间布局的最优比例进行求解,并计算得到了十年间海水养殖空间布局的优化路径。池塘、底播、浅海养殖的现状比例为48%、48%、4%,最优比例为38%、48%、14%;池塘养殖经过2%、2%、2%、5.3%、5.1%、4.7%、4.4%、4%、3.5%、2.9%的优化率,在2020年达到38%的最优占比;底播养殖经过前三年8.8%、8.5%、8.1%的优化比率在2013年达到最大占比51.4%之后连续七年经过5%的优化比率在2020年恢复至最优比例48%;浅海养殖连续十年经过20%的优化比率,最终达到14%的最优占比。经过十年不断的优化,池塘、底播、浅海的养殖面积在2020年都将会达到规划的理想面积1104935hm2、1405817 hm2、480893.6 hm2。

Based on the space layout optimization path and decision model ,it figures out the optimal pro- portion and the optimized path of the marine fisheries space layout. The recent proportion of pond culture and bottom sowing culture and shallow marine culture is 48% and 48% and 4%, and the optimized proportion is 38% and 48% and 14%. The pond culture experiences the optimization proportion of 2% ,2% ,2% ,5.3%, 5.1%,4.7% ,4.4% ,4% ,3.5% ,2.9%,and reaches the 38% in 2020. The bottom sowing culture experiences the optimization proportion of 8.8%,8.5%,8.1% in the first three years, and then experiences the 5% in the last seven years to reaches the 48%. The shallow marine euhure experiences the optimization proportion of 20% in the ten years, and rises to the 14%. Through the ten years＇ optimization, the three kinds of areas will reach the optimized proportion in 2020.
