摘要:土地利用变化是当前研讨的热门议题,通过土地利用变化模型精确的预估出土地利用变化趋向是其核心目标。同时面对大数据的时代,针对土地利用变化模型在运行上花费时间较长的问题,将基于大数据技术的MapReduce模型应用于CA模型之中,建立并行化CA模型,提升其工作速率。经过试验结果能够发现,并行化CA模型在土地利用变化预测中有其优点,将大数据的技术与土地利用变化模型联合起来,能够得到更好的模拟成果。28032 毕业论文关键词:大数据;土地利用变化;CA模型
Based on big data in land-use change model
Abstract: The analysis of land-use trend is one of the hot issue global change research, the core of the research is how to use land-use change model to forecast the tendency of land-use change reasonably and accurately. According to the problem that land-use change model runs in PC has a long time in big data time, this paper gives a CA model based on MapReduce programming model which based on big data technique, build parallel CA model to improve efficiency. The result show that parallel CA model has an advantage in land-use change forecast. It has better result to integrate big data technique and land-use change model.
Key words: Big data; Land-use change; CA model
