摘要
以浏阳市为研究对象,采用Ant-Density求解景观格局优化单目标0-1整数规划模型。研究结果表明:浏阳市共有生态廊道65条、生态节点61个;以特殊生态源地3和12为起点,分别有4条和8条直达路径,最终筛选出12条一级生态廊道,其对应的生态节点为一级生态节点。研究结果可为浏阳市景观廊道和格局优化提供更为具体化、流程化的模式,同时更加具有指导浏阳市景观格局优化的实践操作意义。
Taking Liuyang City as the research object,ant-density was used to solve the landscape pattern optimization single objective 0-1 integer programming model.Results show that:totally there were 65 ecological corridors,61 ecological nodes.Taking the special ecological source regions 3 and 12 as the starting point,there were 4 and 8 direct routes respectively.Finally,12 first-level ecological corridors were selected,and their corresponding ecological nodes were first-level ecological nodes.The results may provide more concrete and streamlined model for the landscape pattern optimization in Liuyang City,and also owned practical and operational significance to guide the landscape pattern optimization in Liuyang City.
