摘　　要：人口活动对于城市发展至关重要。本文基于POI、百度热力图和遥感影像数据,以及核密度计算、神经网络分类法、叠加分析等方法,提出一种城市建成区人口活动强度分级方法。通过对沈阳市进行实验,结果表明:沈阳市人口活动强度在空间上存在着分异性。其中,人口活动高强度区域约占建成区面积16%,覆盖POI数量约为总数67.8%;中强度区域约占建成区面积12%,覆盖POI数量约为总数22%;低强度区域约占建成区面积72%,覆盖POI数量约为总数10.2%。实验结论:本文提出的分级方法能够对城市建成区人口活动强度进行有效分级,其成果可以为城市规划管理提供参考依据。Population activities are crucial to urban development.Based on POI,Baidu heat map and remote sensing image data,as well as neural network,kernel density calculation and superposition analysis,this paper proposes a grading method for population activity intensity in urban built-up areas.By conducting experiments on Shenyang city,the results show that there is spatial heterogeneity in population activity intensity in Shenyang city.Among them,the high-intensity area of population activity accounts for about 16%of the built-up area,and the number of POIs covered is about 67.8%of the total;the medium-intensity area accounts for about 12%of the built-up area,and the number of POIs covered is about 22%of the total;the low-intensity area accounts for about 72%of the built-up area,and the number of POIs covered is about 10.2%of the total.Conclusion:The grading method proposed in this paper can effectively grade the intensity of population activities,and its results can provide a reference basis for urban planning and management.
