摘　　要：传统的区域景观生态敏感性评价系统因景观数据量大,使得系统运行流畅度较差。为此,提出基于Unity3D的区域景观生态敏感性评价系统。在硬件设计上,选择MT9V022作为核心芯片,结合FPGA控制景观数据的传输,设计FIFO与SDRAM相连电路,保证数据安全存储;在软件设计上,根据获取的景观数据,使用Unity3D生成区域景观生态模型,通过该模型确定敏感性因子,计算各个因子的权重与评价得分,求得敏感性综合评价值,结合敏感性评价等级表实现敏感性评价。结合硬件和软件设计完成整个系统设计。测试结果表明,与传统的敏感性评价系统相比,文中设计的基于Unity3D的区域景观生态敏感性评价系统随着数据量的增加,依然能够流畅运行,说明该系统适合应用在实际项目中。As the traditional regional landscape ecological sensitivity evaluation system has poor running smoothness due to the large amount of landscape data,a regional landscape ecological sensitivity evaluation system based on Unity3D is proposed.In terms of hardware design,MT9V022 is selected as the core chip,which combines with FPGA to control the transmission of landscape data,and the circuit connecting FIFO and SDRAM is designed to ensure the safe storage of data.In the software design,Unity3D is used to generate the regional landscape ecological model according to the acquired landscape data,by which the sensitivity factors are determined.The weights and evaluation scores of each factor are calculated,and the comprehensive evaluation value of sensitivity is obtained,and the sensitivity evaluation is realized by combining the sensitivity evaluation level table.The overall system design is completed in combination of the hardware and software design.The testing results show that,in comparison with the traditional sensitivity evaluation system,the designed regional landscape ecological sensitivity evaluation system based on Unity3D can still run smoothly with the increase of the amount of data,which indicates that the system is suitable for application in the actual projects.
