白鹿原文化产业基地生态景观规划模式研究

Research on Ecological Landscape Planning Mode of Bailuyuan Cultural Industry Base

当前生态景观规划模式合理性较差且规划速度较慢,提出基于果蝇的生态景观规划模式。提取可规划景观群空间信息特征,将其代入多目标白鹿原产业基地生态景观规划问题模型建立中,得到生态景观非空间规划模型目标函数和生态景观空间规划模型目标函数。利用果蝇法对所建模型进行求解,设置果蝇的初始位置和搜索方向等参数,计算食物味道浓度的判定值,以此得到各个果蝇位置食物浓度和浓度最高的果蝇位置。保留最优位置,即是最优生态景观规划方案。针对白鹿原产业基地生态景观规划过程中的环境保护问题,提出完善生态景观规划过程中的监测系统、改善景观规划时能源的使用结构等建议。实验表明,该模型景观规划耗时短,规划合理性系数最高为0. 97。该模型可有效提升景观规划速度和合理性,具有较强的可行性。

The current ecological landscape - planning model is less reasonable and the planning speed is slower, and the ecological landscape planning model based on fruit fly is proposed. The spatial information characteristics of the landscape group can be extracted and substituted into the multi - objective Bailu original industrial base ecological landscape planning problem model. The objective function of the ecological landscape non - spatial planning model and the objective function of the ecological land-scape spatial planning model are obtained. The fruit fly method was used to solve the model, and the parameters such as the initial position and search direction of the fruit fly were set, and the judgment value of the taste concentration of the food was calculated, thereby obtaining the position of the fruit fly with the highest food concentration and concentration in each fruit fly position. Retai- ning the optimal location is the optimal ecological landscape planning solution. In view of the environmental protection issues in the ecological landscape planning process of Bailuyuan Industrial Base, suggestions for improving the monitoring system during the ecological landscape planning process and improving the energy use structure during landscape planning are proposed. Experi- ments show that the landscape planning of this model takes a short time, and the planning rationality coefficient is up to 0.97. The model can effectively improve the speed and rationality of landscape planning and has strong feasibility.
