Since the 1990s, the Yellow River stream has been temporarily interrupted for several years, which affects the development of society, the economy and human life, limits the economic potential of the drainage areas, and especially causes great harm to regions on the lower reaches. Based on the analysis of the relationship between the development of society and economy and water scarcity, the author thinks it is necessary to optimize and adjust the industrial structure that has extravagantly consumed enormous amounts of water, and to develop ecological agriculture, industry and tourism which are balanced with the ecological environment. Finally, the author puts forward several pieces of advice and countermeasures about how to build the economic systems by which water can be used economically.

Regional CO_(2. emissions are closely related to their territorial function, which is the major role a region plays in sustainable processes on the earth's surface. Given that china is implementing a top-down emission allocation quota strategy, studying the impact of a territorial function on emissions addresses the research gap from a spatial integration *** investigating the effects of three basic functional territories(urbanization zones(UZ), food security zones(FSZ), and ecological security zones(ESZ)), horizontal spatial structure and vertical combinations of functional territories on CO_(2. emission patterns in china, we found that functional territory patterns were highly coupled with the spatial distribution of CO_(2. emissions, with a ratio of CO_(2. emissions from UZ–FSZ–ESZ was stable at around 5:2.1 from 2.00 to 2.17. Spatially, CO_(2. emissions in FSZ and ESZ were 1.06–2.12.times higher than the average value within 2.0 km from the UZ. As territorial function combination increased with spatial upscaling, the emission characteristics attributable to functional territories became indistinct. The findings above can provide a basis for the long-term prediction of CO_(2. emissions from spatial dimension, support scientific guidance for inter-zone cooperation and classified management of carbon emissions with the major function oriented zones as impetus.

We construct a dual-layer coupled complex network of communities and residents to represent the interconnected risk transmission network between communities and the disease transmission network among residents. It characterizes the process of infectious disease transmission among residents between communities through the SE2.HR model considering two types of infectors. By depicting a more fine-grained social structure and combining further simulation experiments, the study validates the crucial role of various prevention and control measures implemented by communities as primary executors in controlling the epidemic. research shows that the geographical boundaries of communities and the social interaction patterns of residents have a significant impact on the spread of the epidemic, where early detection, isolation and treatment strategies at community level are essential for controlling the spread of the epidemic. In addition, the study explores the collaborative governance model and institutional advantages of communities and residents in epidemic prevention and control.

This paper presents information on the particle size characteristics of suspended sediment transported by the Liu River, which has the most serious erosion and sedimentation problems in the northeast of china. The median (d50) particle size for the individual stations on the Liu River ranged from 0.03.3.to 0.0588 mm. Particles 3..3. and >0.05 mm of ranged from 2..3.to 53.7%. Spatial and temporal variations were noticeable in the particle size composition of suspended sediment within the study basins. At different locations the sediment particles size varies as a result of differences in catchment characteristics. The preferential deposition of the coarser size fractions has resulted in downstream fining of the suspended sediment load. In the flood season the suspended sediment particle size was finer than that in low flow season. The relations among water discharge, suspended sediment concentration, and sediment particle size are complicated. At small water discharge or suspended sediment concentration, with the increase of water discharge or sediment concentration the particle size of suspended sediment decreases to a minimum. However, when the water discharge or sediment concentration exceed certain threshold values (turning points) the particle size increases or remains constant with the increase of water discharge or sediment concentration. The tuning points are different in different rivers. Thus, their relations are double-valued. The negative relation between suspended sediment particle size and flow discharge reflects the importance of supply conditions and the positive relation reflects that the flow and hydraulics take a greater role in sediment transportation. On the whole, variation of the sediment particle size is subject to many factors such as the hydraulic conditions, the type and extent of erosion, human activities, vegetation coverage, hydraulic projects, and sediment supply. The findings reported in this paper have imp

从金融可得性视角探究金融发展与碳排放之间的关系对中国经济低碳发展具有重要意义。本文利用金融分支机构地理信息,构造县域范围以及企业邻近一定距离范围内金融可得性指标,结合县域二氧化碳排放栅格数据以及中国工业企业污染排放数据,从县域和企业两个角度研究提升金融可得性对碳排放的影响。研究发现,县域金融可得性每提升1%,县域二氧化碳浓度下降4.1%;同时,在工业企业邻近5~15公里范围内,金融可得性每提升1%,企业二氧化碳排放减少4.4%~5.4%。该结论通过了替换核心解释变量、工具变量估计以及考虑其他政策冲击等一系列稳健性检验。异质性分析显示,在中国经济增长较快地区、民营企业以及较大规模企业中,金融可得性的碳减排效应更为突出。机制分析发现,提升县域金融可得性可以促使产业结构升级并增加县域专利发明数量;提升企业金融可得性可以促进企业能源结构清洁化、增加企业绿色专利发明数量以及减少重污染企业生产规模。进一步拓展研究发现,提升金融可得性可以缓解县域间碳排放的横向差异。

“全球南方”是中国与拉美地区的共同属性,是推动构建中拉命运共同体的重要纽带。运用国际政治社会学理论分析发现,“全球南方”的崛起是“全球南方”国家共有认知、国际社会实践行动和国际体系演化蜕变互促互构的结果。中国是“全球南方”的天然成员,“全球南方”是中国与拉美的共有认知,独立自主是中国与“全球南方”的共同底色,发展振兴是中国与“全球南方”的共同使命,公道正义是中国与“全球南方”的共同主张。面向现实进展,中拉合作在加强政治沟通、扩大经贸互助、加深民心相通、升级科技合作等方面呈现出互动实践新动向。随着“全球南方”崛起,伴随区域冲突加剧,国际体系演化蜕变加速,中国与拉美在“全球南方”集体认同下的合作机制建设加速推进,为中拉命运共同体的构建提供了新动能,即有利于进一步凝聚升华中拉合作共识,加固中拉合作基础,拓展中拉合作领域,加速中拉合作进程。目前,中拉合作也面临经济发展水平存在差异、合作机制不够完善、西方大国有意干扰和人文交流不足等新挑战。面向未来,中国与拉美应在“全球南方”崛起的背景下乘势而上,从强化经贸联系、深化身份认同、巩固合作成果、共享发展经验、拓展多边合作、维护公平正义、坚持开放包容和开展民间外交等方面入手,推动中拉合作实现高质量发展。
