绿地和水体对缓解热岛效应和改善生态环境效果显著,但因城市空间稀缺导致建设机会成本高,提升蓝绿空间绩效研究亟需深化。本文构建基于成本−收益分析的降温绩效评估模型,定量测量不同规模和类型的蓝绿空间斑块降温效果,以北京市为研究区,利用2010—2020年3期土地利用与地表温度数据,评估大于1 hm^(2)蓝绿空间辐射范围的降温绩效。主要研究结论如下:①研究期内北京市蓝绿空间面积不断增加,呈现由小型面积(Ac)(1≤Ac<2 hm^(2))为主向中型(2≤Ac<10 hm^(2))和大型(Ac≥10 hm^(2))转变;水域持续增加,而林地、草地和混合类型减少;三环以内老城区面积基本持平,而四环减少、五环增多。②根据缓冲区降温模型,北京市蓝绿空间的降温区范围不断增加,从类型结构上看,大中型蓝绿空间形成的降温区增加,而小型蓝绿空间的降温区减少;林地面积虽然减少,但其降温区面积却在增加,而水体降温区面积增长不及自身面积增长。③不同类型蓝绿空间绩效水平呈现先上升后降低的特征,小型和中型混合类型、大型水体的降温绩效比其他同等规模的绩效更好。因此,优化蓝绿规模和类型结构、调整空间形态布局、改善生态空间质量对充分发挥蓝绿空间降温效应起到重要作用,为城市生态环境改善与可持续发展提供新思路。

Heart failure with preserved ejection fraction(HFpEF)has an estimated incidence rate of approximately.27 cases per 10,000 person-y.ar[1].Furthermore,the prevalence of HFpEF is on the rise and is expected to exceed that of heart failure with reduced ejection fraction(HFr EF)[2].In the near future,HFpEF is expected to become the predominant subty.e of heart failure[2].

Android smartphones largely.dominate the smartphone market. For this reason, it is very.important to examine these smartphones in terms of digital forensics since they.are often used as evidence in trials. It is possible to acquire a phy.ical or logical image of these devices. Acquiring phy.ical and logical images has advantages and disadvantages compared to each other. Creating the logical image is done at the file sy.tem level. Analy.is can be made on this logical image. Both logical image acquisition and analy.is of the image can be done by.software tools. In this study. the differences between logical image and phy.ical image acquisition in Android smartphones, their advantages and disadvantages compared to each other, the difficulties that may.be encountered in obtaining phy.ical images, which ty.e of image contributes to obtaining more useful and effective data, which one should be preferred for different conditions, and the benefits of having root authority.are discussed. The practice of getting the logical image of the Android smartphones and making an analy.is on the image is also included. Although root privileges are not required for logical image acquisition, it has been observed that very.limited data will be obtained with the logical image created without root privileges. Nevertheless, logical image acquisition has advantages too against phy.ical image acquisition.
