丧葬仪式体现了民众最传统的社会法则与文化逻辑,具有重要的民俗教育功能。南岭走廊瑶族丧葬仪式通过文本演述、“送灵安魂”、上祭守孝、集体互助、空间净化等环节,创造出一个民俗教育的濡化空间,对个体进行浸润与教育。一方面重视传承孝道观念,进行悲伤纾解与情感疗愈;另一方面重建社会秩序,包括强化三界空间认知与象征秩序,以及经由集体分担死亡危机恢复社区公共秩序。对丧葬中多维民俗教育方式的研究,有利于深入探究中华文化“大传统”与“小传统”如何在民众生活中融合共生,为铸牢中华民族共同体意识研究提供新的思路。同时,民众乐观豁达面对死亡的生命智慧对于当今社会的生命教育具有深刻的反思和借鉴意义。

全球特别是热带国家间地缘合作驱动着边境森林转换等土地利用变化。相较热带特定森林类型扰动,边境森林干扰及其对国家间地缘合作响应机制等研究明显滞后。中南半岛与其毗邻乃至域外大国地缘合作和博弈已逾30年,2020、2021年新冠疫情在迟滞地缘合作与边境发展之余是否对边境森林扰动施加影响?论文利用2017—2021年Sentinel-210 m土地覆被产品,基于森林转换流向与核密度等方法,从农用地扩张与建设用地扩展评估了中南半岛及其邻国边境森林扰动过程与特征。结果表明:①森林是半岛13条边境地带基质覆被类型,耕草地次之,建设用地在口岸占据优势。②森林干扰是边境土地覆被与景观变化主导形式,面积占近50%,耕地、草地变化所致农用地扩张与建设用地扩展贡献比为9∶1。③农用地扩张与口岸建设用地扩展分别是边境森林扰动主要与次要驱动因素。前者所致森林扰动超7成,后者所致相应占比为3%且呈逐年上升态势,同时其对森林扰动直接和间接影响国别差异突出。④新冠疫情致使所有边境森林扰动减弱,柬埔寨居首位,柬埔寨—老挝边境最突出。边境两侧国家森林扰动减弱具有同步和异步影响特征。

Due to the over use of available water resources, it has become very important to define appropriate strategies for planning and management of irrigated farmland. In this paper, Beijing-Tianjin-Hebei (Jing-Jin-Ji) region was chosen as the case study area for its special political and economic status and its severe water problem. To achieve effective planning, the information about crop water requirements, irrigation withdrawals, soil types and climatic conditions were obtained in the study area. In the meantime, a GIS method was adopted, which extends the capabilities of the crop models to a regional level. The main objectives of the study are: 1) to estimate the spatial distribution of the evapotranspiration of spring maize; 2) to estimate climatic water deficit; 3) to estimate the yield reduction of spring maize under different rainfed and irrigated conditions. Based on the water deficit analysis, recommended supplemental irrigation schedule was developed using CropWat model. Compared to the rainfed control, the two or three times of supplemental water irrigated to spring maize at the right time reduced the loss of yield, under different scenarios.

成像光学系统的观测场景愈发复杂,为了实现物方到像方复杂的投影映射,传统的光学设计方法需优化控制不同视场的像高,该方法采样追迹计算量大。文中提出采用视场相关的局部参数作为优化控制目标,由局部焦距和局部F数实现复杂物像映射关系和分辨率的调控,并达到同步优化提升相对照度的效果。采用该方法分别成功设计了中央-20°~20°视场f-tanθ等线投影,边缘±20°~±60°视场f-θ等距投影,以及中央-16°~16°视场角分辨率相同、边缘±28°~±60°视场角分辨率相同且中央视场角分辨率为边缘视场角分辨率1.5倍/0.667倍的三款120°视场广角镜头。基于视场相关局部参数优化的光学设计方法展现了灵活的物像映射调控能力,对于光学系统在复杂类型观测场景中的应用具有非常重要的价值。

Building a Green Silk Road by integrating the Sustainable Development Goals(SDGs) is one of the Belt and Road Initiative(BRI) visions, but the BRI faces enormous challenge that is the conflict between economic development and ecological *** the current scale and trend of the impact of human activities on the ecosystem is the preliminary work to ensure that human activities do not exceed the ecological carrying capacity under the BRI. This study evaluated the ecosystem pressure in countries along the Belt and Road(B&R) from 2000–2017 based on the supply-consumption balance relationship of ecological resources. Net primary productivity(NPP) is taken as the measure of ecological resources, and the supply level and consumption intensity of ecological resources is estimated based on remote sensing data and statistical data, respectively. Results show that thirteen countries with overconsumed ecological resources concentrated in the West Asia/Middle East. Although the intensity of the ecological resource consumption correlated with ecological resource endowments, the ecosystem pressure was determined by social development dependence on the ecological resources at the same ecological resource endowments level. Nearly 80% of countries along the B&R suffered from significantly increased(P < 0.05) ecosystem pressure during 2000–2017, since most of the countries along the B&R were developing countries,and their economic development was highly dependent on ecological resources. Some West Asia/Middle East countries successfully mitigated the ecosystem pressure by importing feed for livestock. Likewise, the Southeast Asian islands benefitted from the import of agricultural products. The results highlight that the BRI should reduce the dependence of social development demands on local ecological resources by international trade for ensuring the increasing ecosystem pressure trend within the ecological carrying capacity.
