    Basic research funded by public science is the source of technological innovation. Based on the linear model of fund assistance-basic research-technology R&D, this research adopts the method of scientometrics to measure the technological influence of the basic research funded by the National Natural Science Fund Committee(NSFC). NSFC funded projects represent the foundation, scientific papers represent basic research, patent literature represents technology research and development. Based on the data of highly cited papers funded by NSFC in the past ten years, this paper analyzes the situation of patents cited by highly cited papers from the perspectives of time, discipline and research direction, country and institution. The results show that under the support of the National Natural Science Foundation, not only a large number of high-impact papers have been produced in China, but also these papers have a high technical impact, which has an impact on the two fields of science and technology. The National Natural Science Foundation plays an important role in promoting our technological innovation.

    In response to complex issues such as global climate change, human health, water supply and environmental protection, and sustainable development etc., international cooperation in Lake Science is growing highlighted. The enhanced cooperation seems to be necessary to achieve the goal of ecological civilization construction in China. This paper uses bibliometric methods to analyze the articles published in scholarly journals during 2001-2020 through Web of Science (WOS), issued on the topic of international cooperation on Lake Science. In addition,7 representative lake research institutes worldwide are selected for comparative analysis on major contents of international cooperation, and the main directions and the trend of international cooperation in Lake Science are discussed. The results show that the node advantages in the international cooperation network of Lake Science are decreasing, and more international cooperatives from different countries(regions)tend to be active. On the other, the number of cooperative countries(regions)and the international cooperation rate of China are growing rapidly, which reflects the important position of China in international cooperative relations. In western countries, their research team are generally influential on international cooperation, accordingly, the Chinese research team need to improve its academic influence. The important issues of international cooperation on Lake Science are about human-lake environment coordination, lake-basin management, lake ecological degradation and restoration, and response to global climate change, etc. Finally, this paper puts forward the suggestions that China should strive continuously to strengthen international cooperation in Lake Science research in the future.

    In recent years, there has been a rapid increase in the worldwide population of individuals with diabetes, and the prevalence of diabetes among adults in China has reached 11. 9%. Medications play a pivotal role in the management of diabetes. Glucokinase activators (GKA) have garnered considerable attention in the research and development of novel medications for the treatment of type 2 diabetes, owing to their ability to target glucokinase, a key regulator of glucose homeostasis in hepatic cells. An examination of the current status of patents concerning glucokinase activators can offer valuable scientific and technological insights to inform decision-making and drive the progress of industries associated with glucokinase activators. This study utilizes the patent metrology method, drawing on the Derwent patent database and Cortellis database as primary data sources, to analyze patent application trends, patent distribution, patent applicants, their pharmaceutical products, patent technology composition, hotspots, and the technological development trajectory. The findings indicate that GKA technology is in a state of ongoing development, with the United States and Japan emerging as the main regions for its distribution. Roche, AstraZeneca, Pfizer, and Hualing Pharmaceutical Company have filed the highest number of patent applications. The patented technology encompasses seven key areas, including drug structure, drug dosage form, drug compatibility, pharmaceutical chemistry, and disease treatment. Based on the analysis results, several recommendations are put forward in the field of glucokinase activators in China, aiming to provide references for future patent application strategies and innovative product research and development.

    This paper analyses the time trend, national (regional) distribution, distribution of major applicants, technology composition and regional distribution of patent applications related to the preparation of magnesium, lithium and its intermediate alloys by molten salt electrolysis, and then provides guidance for China’s technological research and patent application layout in this field. The study found that China’s patent quantity increase year by year, especially between 2011-2022, The number of China’s patent applications reached 2,042, accounting for 80. 8%. At this stage, China has an absolute advantage in the number of patent applications, but the core patents are missing and there are no high-value patents; China’s top 20 applicants are mainly universities and scientific research institutes, and there are few applications for cooperation between these universities or scientific research institutes and enterprises, and the conversion rate of technological achievements is relatively low. On the other hand, the United States, Japan, Canada and other countries have the strongest scientific research capability and technological strength, and their main advantages are reflected in the core technology of electrolytic equipment (electrobath). At the end of this paper, specific suggestions are also put forward to strive for China’s breakthroughs in the development of high-value patents in this field, and promote the high-quality development of the industry.

    The carrying capacity of resources and environment is an important criterion to study the development potential of regional human-land system and to evaluate the service function of natural ecosystem. Based on systematic combing of the related researches, the carrying capacity of resources and environment is re-recognized as follows: (1) The carrying capacity of resources and environment is the elastic threshold of the mathematical relationship between the supply side of resources and environment and the demand side of regional development in a certain space-time scale, which can be expressed as an equation of state. (2)Constraints such as resource utilization’s upper limit, environmental quality’s bottom line and ecological red line are the master controlling factors for building the comprehensive evaluation model of resources and environmental carrying capacity. (3) Identifying the main control factors, establishing the supply and demand list and defining the supply and demand network are the key links which need to be addressed in the application of the model. (4) The rapid development of modern geoscience technology, system structure modeling technology, geographic detector, system dynamics and other technical methods can provide key technical supports for the practical application of the model. Finally, according to the analysis, a comprehensive evaluation model of the carrying capacity of resources and environment based on the dynamic balance of supply and demand is constructed. Moreover, the model is applied to an empirical study of the typical area in the upper reaches of the Min River, and the elastic threshold of the land resources carrying capacity in the area is dynamically calculated and the carrying condition is evaluated. Based on the dynamic balance of supply and demand, research on the theory and method of comprehensive evaluation of resources and environment carrying capacity can provide a new measuring tool for carrying capacity of regional resources and environment.
