The Yellow River soil and water conservation ecological construction and protection project was completed in 2008 in Mangshan Mountain area along the Yellow River Basin in the northwest of Zhengzhou. Continuous positioning observations of the ecosystem have been conducted since 2010. Using the ecological measured data of Mangshan, Zhengzhou from 2010 to 2020, the impact of ecological protection of the Yellow River on the local microclimate of Mangshan was analyzed by using one-variable linear fitting and anomaly method. The results show that in the past 10 years, the microclimate of Mangshan Mountain has changed significantly. The average values of the measured annual air temperature, annual maximum temperature, annual minimum temperature, air humidity and precipitation are 15.7 ℃, 40.35 ℃,-9.15 ℃, 54.53% and 406.35 mm respectively. Except precipitation, the changes of other climatic factors are on the rise. The decrease in precipitation, the increase in temperature, the increase in temperature difference and the increase in air humidity indicate that the water-retention functions of soil and surface vegetation are enhanced, and the ecological protection of the Yellow River has played a good role in improving the microclimate of Mangshan, Zhengzhou.

Because circularly polarized luminescence(CPL) has unique properties including extensive optive information, large-capacity optical information and angular independence, chiral materials with CPL emission present increasing potential for applications in diverse fields such as storage of information, bio-encoding, 3D optical displays and even catalysts for asymmertirc photochemical synthesis. As an important approach, supramolecualar self-assembly can provide a convenient method to construct the CPL materials by introducing chiral source and achiral fluorescent moleculars into the supramolecular system through different nocovalent interactions (such as π-π stacking, electrostatic interactions and hydrogen bonding). The chiral arrangement of the luminescent units in the assembly plays a key role in controlling the CPL emission (including the intensity and sign) of such materials. Although the study of CPL materials lasts several years, an open question that has long been a point of concention is how to achieve the high performance CPL materials. A high degree of dissymmetry ratio is also the urgent challenge. Therefore, it is vital to develop effective ways for the CPL materials with the high dissymmetry factor. In this review, we focus on the present progress on the chiral materialswith induced CPL emission by using template including chiral gel nanotube, mesoporous template, liquid crystalline polymer and helix formed by polymer. The dissymmetric factor and luminescent intensity of the obtained CPL materials in different assemblies were intensively discussed depending on different templates. We also present some perspective on the development of the induced CPL materials and the future application. [ABSTRACT FROM AUTHOR]
