As the two largest “granaries” in China, the Northeast and Huang-Huai-Hai Plains are the main agricultural producing areas in North China, and the soil environmental risk management and control of these areas are vital to the national food security supply lifeline. This study analyzed the soil heavy metal pollution risks of main agricultural producing areas in North China by the potential ecological risk index method. The high-risk areas of Cd pollution are mainly distributed in Shenyang City in the east of Liaohe Plain, Jinzhou City and Huludao City in the south of Liaohe Plain, Shuangyashan in the Sanjiang Plain, Tianjin City in the Haihe Plain, and Xinxiang City in the southwest of the yellow river flood plain; Hg pollution high-risk areas are mainly distributed in Beijing and Tianjin of the Haihe Plain, and around the Shenyang City of the Liaohe Plain. The chemical industry, followed by the livestock and poultry industry, as well as the metal smelting and processing industry, is the major potential source of heavy metal pollution of soil in the Northeast and Huang-Huai-Hai Plains. This study proposed the “one area, one policy” pollution prevention strategy and key environmental protection projects from the aspects of environment monitoring and warning of agricultural products producing areas, clean production of industrial and mining enterprises, and comprehensive treatment of livestock and poultry pollution, which is based on local conditions and classification guidance. This study can provide important references for the strategic planning of sustainable development of the ecological environment of major agricultural producing areas in North China.

Special equipment are important for the economic and societal development of a country. Implementing intelligent manufacturing in the special equipment field could facilitate the transformation and upgrades of the special equipment manufacturing industry of China, and it is also an essential component for the China Manufacturing 2025 plan. In this article, we first analyze the characteristics and current status of special equipment in China and summarize the demand for intelligent manufacturing of special equipment. Then we propose some measures and development ideas for promoting the special equipment manufacturing industry from big to strong. We propose that the guiding ideology should be parallel development; the Industry 2.0, Industry 3.0, and Industry 4.0 should be promoted in parallel in the special equipment industry. The development of intelligent manufacturing of special equipment should focus on product traceability, intelligent quality management, and real-time monitoring of dynamic risks. Based on this, intelligent connection is introduced as a technology path for developing intelligent manufacturing of special equipment, and the concept of intelligent connection is further analyzed. Furthermore, the key tasks for future development are building an intelligent connection network of special equipment and developing intelligent applications.

The river networks in the plains of China are in low-lying terrain with mild bed slopes and weak hydrodynamics conditions. Filled with intense human activities, these areas are characterized by serious water security problems, e.g., frequent floods, poor water self-purification capabilities, and fragile water ecosystems. In this paper, it’s found that all these problems are related to hydrodynamics, and the spatiotemporal imbalance of river network hydrodynamics is identified as the common cause of these water-related problems. From this, a theory for the hydrodynamic reconstruction of plain river networks is proposed. In addition to the importance of the flow volume, this theory highlights the role of hydrodynamics and limited energy in improving the ecological water environment. The layout of water conservancy project systems (e.g., sluices and pumping stations) is optimized to fully tapping the potential integrative benefit of projects. The optimal temporal and spatial distributions of hydrodynamic patterns is reconstructed in order to meet the needs of the integrated management of complex water-related problems in river networks. On this basis, a complete theoretical method and technical system for multiscale hydrodynamic reconstruction and multi-objective hydraulic regulation in plain river networks with weak hydrodynamics is established. The principles of the integrated management of water problems in river network areas are put forward. The practical application and efficacy of the theory are demonstrated through a case study aiming to improve the water quality of the river network in the main urban area of Yangzhou City.

Comparing the total pollution load into rivers in 2005 with the one in 2000, the analysis suggests that the percentage of point sources in total kept reducing year by year, and the non-point sources increased significantly, especially total phosphorus (TP) whose amount of pollution from non-point sources have already exceeded that from point sources. The total amount of pollution from non-point sources was almost equal, but its composition changed. The pollution from rural domestic sewage ranks first and the pollution from aquaculture and fields ranks second in the total amount of pollution from non-point sources. Based on the analysis of causes of non-point sources pollution, this essay gives some suggestion on the control of non-point sources pollution in plain river network of Taihu Basin.

The spatial variability and distribution of NO3- N in shallow groundwater in Huang-Huai-Hai Plain were studied by means of GPS and GIS technology. The results indicated that it did not show a spatial structure at the sampling density of 35～50 km in shallow groundwater. The spatial variability of NO3-N content belonged to high intensity. The area of NO3—N concentration over 20 mg· L-1 was about 10% of the whole Huang-Huai-Hai Plain, and was mainly distributed in the zone from Tianjin to Jinan and Xincai, Fuyang and Bengbu in the Huaihe River Basin. The area of NO3-N content in the range of 10—20 mg·L-1 was distributed in the region from Xuzhou to Lianyungang in Jiangsu Province and Weifang,in Shandong Provence, which was about 11.5% of the Huang-Huai-Hai Plain. The NO3—N concentration in the shallow groundwater was related to the groundwater depth. The NO3-N concentration was usually over 20 mg·L-1 when the groundwater level was less 3 m, while the NO3—N content was less 10 mg·L-1 when the groundwater level was over 10 m. It implied that the affecting depth of the nitrate leaching on the groundwater was less than 10 m. These results were beneficial to making decision for increasing water and fertilizer utilization efficiency and to the sustaining agricultural development in Huang-Huai-Hai Plain.

An energy-water coupling model is established in this paper based on long-range energy alternatives planning (LEAP)
and water evaluation and planning (WEAP), scenarios are then designed to explore the energy- and water-saving effects of different
policies in Beijing in the future and their coupling effects, and sensitivity analysis of the results is also conducted. Results show that the total energy consumption in Beijing will grow gradually by year, while water shortage is unlikely to occur. During the 13th Five-Year Plan, the total energy-saving amount owing to water-saving policies is 1.003 million tonnes of standard coal, and the total water-saving amount owing to energy-saving policies has reached 276 million cubic meters. The energy demand and water demand by residents’living, the service industry, the construction industry, and the traditional manufacturing industry are correlated, as they are critical energy-water coupling sectors. In terms of energy- and water-saving effects in different scenarios and periods, the industrial structure optimization policy shows great energy-saving potentials in the short term, while irrigation technology innovation and planting structure optimization in the agricultural sector have both good energy- and water-saving effects in the short term. A coordinated energy- and water-saving effect can be found in energy-saving scenarios in the service industry and the industrial sector. As for policies in the same sector, regulation on energy use intensity can achieve an obvious coordinated energy- and water-saving effect.
