基于杭州市1914—2018年间6期近代地图与遥感影像数据，通过目视解译数字化的近代地图，使用面向对象的分类方式对CORONA、Landsat TM和OLI影像进行分类并提取建设用地数据，计算扩张速度、重心变化、景观格局指数和增长类型，分析建设用地的扩张过程与扩张模式。结果表明：（1）近百年来杭州城市建设用地扩张明显，扩张过程主要集中在改革开放后。（2）杭州城市重心经历了“北—西北—北—东南—南”的变化过程，由向单一方向扩张转变为多方向均衡发展的态势。（3）建设用地扩张过程基本符合“扩散—融合”假说；城市核心区呈现蛙跳增长、填充增长、边缘增长依次主导的螺旋式发展过程，研究区域整体表现为边缘增长始终占相对重要地位的特征。（4）通过近代地图与遥感影像的集成分析，为长时间尺度的城市研究提供了一种路径。

[Objective] The aim of this study is to explore the response mode and degree of ecological environment to the ecological efficiency of cultivated land use, which is of great significance for realizing the coordinated development of agricultural sustainable development and ecological environment protection. [Methods] Shaanxi Province was taken as the research area. Remote sensing ecological index was calculated to characterize the ecological environment quality of Shaanxi Province based on remote sensing data. SBM model was used to measure the ecological efficiency of cultivated land use in Shaanxi Province. The geographical weighted regression model was used to explore the response of ecological environment to the ecological efficiency of cultivated land use. [Results] (1) In 2005, 2010, 2015 and 2019, the ecological efficiency of cultivated land use in Shaanxi Province was generally at the medium level, and more than 88% of the areas were classified as low efficiency, low efficiency and medium efficiency. (2) In 2005, 2010, 2015 and 2019, the ecological environment quality of Shaanxi Province was continuously improved, and the ecological environment quality of loess hilly and gully region and Mu Us Sandy Land were significantly improved, and the spatial pattern remained high level in the south and low level in the north in general. (3) There was a significant positive correlation between the ecological efficiency of cultivated land use and the ecological environment in Shaanxi Province, and the spatial distribution of the correlation relationship was unbalanced. [Conclusion] The synergistic development model of ecological environment and ecological efficiency of cultivated land use in Shaanxi Province is not stable, and needs to be further explored and consolidated.

Cybersecurity is currently one of the non-traditional security threats that China and ASEAN share. China's strengthening of cybersecurity cooperation with ASEAN is not only a practical need to create a favorable environment for the development of the digital economy, but also an important step towards building a community of shared destiny in cyberspace. Cybersecurity cooperation between the two sides has solid motivation and broad scope for cooperation, in the meantime, it faces many challenges including the constraint of cooperative level due to limited resource investment, the efficiency of cooperation impacted by delayed capacity building, uncertainty in cooperation brought by the diversity in cooperative models, and complexity intensified by extraterritorial forces. The two sides should strengthen strategic planning in cybersecurity, build relevant rules and standards, promote technology research and development and industrial development, and jointly prevent and respond to interference and damage by extraterritorial forces. The two sides should promote global cybersecurity governance towards a fairer and more reasonable direction by building a resilient and inclusive framework for cybersecurity cooperation.

Using 2-hydroxy-4-methoxybenzophenone as carbon source and ethylenediamine as nitrogen source, an oil-soluble nitrogen doped carbon dots (CDs) with dual absorption of ultraviolet and short-wave blue light is synthesized by hydrothermal method. The composite lens material with ultraviolet light and short-wave blue light shielding effect is prepared by compounding CDs with polymethyl methacrylate. When the mass fraction of CDs is 1%, the average transmittance of the composite lens in the ultraviolet region is 0%, the average transmittance in the short-wave blue light region is 1. 6%, and the absorption efficiency is 99. 6%. It is a strong anti-ultraviolet-short-wave blue light material. [ABSTRACT FROM AUTHOR]

As a strategic channel to achieve effective connectivity of Belt and Road Initiative, the New International Land-Sea Trade Corridor has broad space and foundation for synergy with Lancang-Mekong Cooperation. However, it also faces many challenges, such as differences in strategic demands, interference from major powers outside the region, inadequate customs clearance facilitation, limitation of infrastructure connectivity, industrial synergy problems and so on. Therefore, to enhance the effectiveness and precision of the connectivity, we need to build cooperation consensus among countries, promote cross-border facility connectivity, improve customs clearance facilitation and institutional international mechanisms in an effort to promote high-quality and sustainable development in the Lancang-Mekong region and jointly build a community of shared future.
