In China, meteorological forecasting relies on meteorological data obtained from regional and national stations. However, there were discrepancies between the data collected from the meteorological station at the passion fruit growing base and the data from regional and national stations. Consequently, the high and low temperature disaster indicators determined by the meteorological station at the passion fruit growing base cannot be applied to meteorological forecasting. To address this issue and facilitate the monitoring and early warning of high and low temperature disasters in passion fruit cultivation in Fujian, China, we used multi-source hourly temperature data (including the data from meteorological observation stations in passion fruit growing bases, the nearest regional stations, and national surface conventional meteorological observation stations) in three cities in southwestern Fujian (Longyan, Sanming, and Zhangzhou) spanning the years 2020 to 2022. By employing comprehensive statistical analysis methods (0.5 interval division and Cumulative frequency), we identified that passion fruit in southwestern Fujian was susceptible to high temperature disasters during the blooming-fruiting period, as well as low temperature disasters during the sprouting period. Consequently, we developed high and low temperature disaster indicators based on data from regional and national stations for different phenological periods of passion fruit in this region.

为探求造成吉林省玉米倒伏灾害的天气系统类型、特征及发生规律,利用历史灾情和玉米发育期数据、ERA5再分析资料,采用典型个例分析方法,对吉林省造成玉米倒伏灾害的天气系统进行了分析总结。结果表明:造成玉米倒伏灾害的天气系统主要有台风、东北冷涡、低空切变线及高空槽。玉米拔节—抽雄期倒伏主要受东北冷涡影响,抽雄-乳熟期主要受低空切变线、高空槽影响,乳熟-成熟期主要受北上台风影响。台风是造成吉林省玉米倒伏最为严重的天气系统,影响范围广,其移动路径对作物倒伏灾害的发生范围起决定性作用,倒伏灾害多发生在台风移动路径的西侧或北侧,地面低压系统的北侧。东北冷涡次之,倒伏主要发生在水汽、动力、热力和对流不稳定条件均最为显著的冷涡东南象限。低空切变线、高空槽影响范围小,低空切变线类倒伏发生位置取决于低空切变线或辐合线的位置。高空槽类倒伏一般发生在高空槽前,地面冷锋附近。

我国国土空间生态修复活动普遍面临着融资困难、资金来源相对单一、金融支持生态产业化不足等问题,为更好地促进市场化手段在相关领域的应用,对典型的生态修复市场化路径进行了系统梳理。结果发现,收益机制不明确、不稳定是阻碍社会资本参与生态修复项目的重要原因;近年来,在中央和地方政府的支持下,各地探索形成了生态系统生产总值(GEP)核算、碳汇交易、生态环境导向的开发(EOD)、绿色金融支持等诸多创新市场化模式。然而,相关实践大多采用试点模式,在体系化、标准化、规范化方面仍不具有推广性。未来,应当着力完善生态要素产权体系,加快建立标准化价值核算体系,全面创新生态产品交易体系,以持续地吸引生态修复的市场化投入。研究结果可为建立我国生态产品价值转化机制提供实践依据,为更好地保障市场体系建立与运行提供支撑。

A water-in-oil microemulsion made up of a cyclohexane/n-hexyl alcohol/Polyethylene glycol tertoctylphenyl/aqueous solution including Bi3+ and VO+3 ions yields the spherical BiVO4 precursors with the size from 5 to 300 nm. Well-crystallized monoclinic scheelite BiVO4 particles with nanometer or micrometer size are fabricated in control by heating microemulsion precursors under various temperatures. The corresponding nucleation and growth process of as-prepared samples has also been investigated via TEM,which demonstrates the detailed morphological evolution of nuclei inside the precursors. As-prepared BiVO4 photocatalysts exhibit enhanced photocatalytic activity under visible-light irradiation in comparison with the bulk BiVO4 prepared by solid-state reaction. The highest RB degrading efficiency of 98% in 180 min under visible-light irradiation is observed for the sample calcined at 600 °C.
