It is an inevitable choice and important way to realize the transformation from traditional agriculture to modern agriculture. This paper reviewed the construction background,functional characteristics and development history of agricultural science and technology parks. It analyzed the current development situations of the provincial agricultural science and technology parks in Jiangyang District,Luzhou City of Sichuan Province. Then,it summarized its experience in park construction and compared with surrounding national and provincial agricultural science and technology parks. It found existing problems including insufficient industry-university-research integration,low level of agricultural intensification,weak functions of public service platforms and brand effect,and insufficient exploration of tourism resources. In view of these problems,it came up with recommendations for development of agricultural Sci-Tech Park District of Luzhou City,including gathering scientific and technological resources,enhancing scientific and technological support,strengthening the high-quality development of the park economy,and building a national 4 A-level excellent scenic spot.展开更多

In 2021, oil and gas fields were widely distributed, the number of non-producing oil and gas fields was large;the whole oil and gas remaining recoverable reserves declined slightly, unconventional oil and gas remaining recoverable reserves dropped significantly;the overall oil and gas production continuously increased, the outputs of key resource-host countries kept year-on-year growth;undeveloped oilfields had abundant reserves and great development potential. Combined with global oil and gas geopolitics, oil and gas industry development trends, oil and gas investment intensity, and the tracking and judgment of hotspot fields, the major trends of global oil and gas development in 2021 are summarized. On this basis, the four aspects of enlightenment and suggestions for international oil and gas cooperation and development strategies are put forward: attach great importance to the obligation of marine abandonment to ensure high-quality and long-term benefit development of offshore oil and gas;adhere to the principle of not going to dangerous and chaotic places, strengthen the concentration of oil and gas assets, and establish multi stable supply bases;based on the multi-scenario demand of natural gas, realize the transformation from integrated collaboration to full oil and gas industry chain development;increase the acquisition of high-quality large-scale assets, and pay attention to the continuous optimization of the shareholding ratio of projects at different stages.展开更多
