The proportion of the tertiary industry and other indicators were used to explore the suitability of the development of eldedy care real estate, and cluster analysis was used to classify the sample areas according to the suitability. The results show that the 18 counties and cities in Ganzhou City could be divided into three categories, areas with poor suitability, areas with development potential, key development areas. Finally, suggestions were put forward that the target market of the development of old-age real estate could be comprehensively analyzed by combining the population development trend of the region with its thoughts and concepts, social and economic development, the maturity of the real estate market and the development of the service industry to ensure the sustainable operation of the old-age real estate.展开更多
为研究陆地表面温度及其衍生指标反演我国大陆土壤水分的适用性,基于 Z -score标准化和相关性分析方法,确定了最优陆地表面温度指标,再基于列联表评估最优指标监测2000—2019年4至10月干旱的适用性。结果表明:对各种土地覆盖类型,陆地...为研究陆地表面温度及其衍生指标反演我国大陆土壤水分的适用性,基于 Z -score标准化和相关性分析方法,确定了最优陆地表面温度指标,再基于列联表评估最优指标监测2000—2019年4至10月干旱的适用性。结果表明:对各种土地覆盖类型,陆地表面温度和土壤水分的相关性最强;在耕地和草地覆盖的半干旱半湿润区,相关性值可达0.7以上,陆地表面温度可以很好地反演中等水分胁迫区域植被根区的土壤水分。陆地表面温度可以监测至少1/4的非随机可预测极端干旱事件,探测率和虚警率分别为0.37和0.12。因此,陆地表面温度可被用于反演大尺度土壤水分并监测干旱。展开更多

文摘LeNet-5卷积神经网络在手写数字库上取得了很好地识别效果,但在表情识别中识别率很低.改进了LeNet-5卷积神经网络,使用浅层卷积结构,连续经过1×1和3×3的卷积层,在每一层的卷积后,加上Z-score标准化处理,使用性能更好的Relu激活函数,此函数计算速度快,减少梯度弥散问题;输出层用softmax函数,该层输出表情图像的概率.仿真结果表明,在JAFFE表情数据库上,即使在小样本数据集的情况下,算法识别率达到79.81%,识别单幅人脸表情图像的平均耗时为0.353 s.
